ApacheCon CFP closing soon (11 February)
Hello, fellow Apache enthusiast. Thanks for your participation, and interest in, the projects of the Apache Software Foundation. I wanted to remind you that the Call For Papers (CFP) for ApacheCon North America, and Apache: Big Data North America, closes in less than a month. If you've been putting it off because there was lots of time left, it's time to dig for that inspiration and get those talk proposals in. It's also time to discuss with your developer and user community whether there's a track of talks that you might want to propose, so that you have more complete coverage of your project than a talk or two. We're looking for talks directly, and indirectly, related to projects at the Apache Software Foundation. These can be anything from in-depth technical discussions of the projects you work with, to talks about community, documentation, legal issues, marketing, and so on. We're also very interested in talks about projects and services built on top of Apache projects, and case studies of how you use Apache projects to solve real-world problems. We are particularly interested in presentations from Apache projects either in the Incubator, or recently graduated. ApacheCon is where people come to find out what technology they'll be using this time next year. Important URLs are: To submit a talk for Apache: Big Data - http://events.linuxfoundation.org/events/apache-big-data-north-america/program/cfp To submit a talk for ApacheCon - http://events.linuxfoundation.org/events/apachecon-north-america/program/cfp To register for Apache: Big Data - http://events.linuxfoundation.org/events/apache-big-data-north-america/attend/register- To register for ApacheCon - http://events.linuxfoundation.org/events/apachecon-north-america/attend/register- Early Bird registration rates end March 12th, but if you're a committer on an Apache project, you get the low committer rate, which is less than half of the early bird rate! For further updated about ApacheCon, follow us on Twitter, @ApacheCon, or drop by our IRC channel, #apachecon on the Freenode IRC network. Or contact me - rbo...@apache.org - with any questions or concerns. Thanks!

Save the date: ApacheCon Miami, May 15-19, 2017
Dear Apache enthusiast, ApacheCon and Apache Big Data will be held at the Intercontinental in Miami, Florida, May 16-18, 2017. Submit your talks, and register, at http://apachecon.com/ Talks aimed at the Big Data section of the event should go to http://events.linuxfoundation.org/events/apache-big-data-north-america/program/cfp while other talks should go to http://events.linuxfoundation.org/events/apachecon-north-america/program/cfp ApacheCon is the best place to meet the people that develop the software that you use and rely on. It’s also a great opportunity to deepen your involvement in the project, and perhaps make the leap to contributing. And we find that user case studies, showcasing how you use Apache projects to solve real world problems, are very popular at this event. So, do consider whether you have a use case that might make a good presentation. ApacheCon will have many different ways that you can participate: Technical Content: We’ll have three days of technical sessions covering many of the projects at the ASF. We’ll be publishing a schedule of talks on March 9th, so that you can plan what you’ll be attending BarCamp: The Apache BarCamp is a standard feature of ApacheCon - an un-conference style event, where the schedule is determined on-site by the attendees, and anything is fair game. Lightning Talks: Even if you don’t give a full-length talk, the Lightning Talks are five minute presentations on any topic related to the ASF, and can be given by any attendee. If there’s something you’re passionate about, consider giving a Lightning Talk. Sponsor: It costs money to put on a conference, and this is a great opportunity for companies involved in Apache projects, or who benefit from Apache code - your employers - to get their name and products in front of the community. Sponsors can start any any monetary level, and can sponsor everything from the conference badge lanyard, through larger items such as video recordings and evening events. For more information on sponsoring ApacheCon, see http://apachecon.com/sponsor/ So, get your tickets today at http://apachecon.com/ and submit your talks. ApacheCon Miami is going to be our best ApacheCon yet, and you, and your project, can’t afford to miss it. -- Rich Bowen - rbo...@apache.org VP, Conferences http://apachecon.com @apachecon - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

ApacheCon Seville CFP closes September 9th
It's traditional. We wait for the last minute to get our talk proposals in for conferences. Well, the last minute has arrived. The CFP for ApacheCon Seville closes on September 9th, which is less than 2 weeks away. It's time to get your talks in, so that we can make this the best ApacheCon yet. It's also time to discuss with your developer and user community whether there's a track of talks that you might want to propose, so that you have more complete coverage of your project than a talk or two. For Apache Big Data, the relevant URLs are: Event details: http://events.linuxfoundation.org/events/apache-big-data-europe CFP: http://events.linuxfoundation.org/events/apache-big-data-europe/program/cfp For ApacheCon Europe, the relevant URLs are: Event details: http://events.linuxfoundation.org/events/apachecon-europe CFP: http://events.linuxfoundation.org/events/apachecon-europe/program/cfp This year, we'll be reviewing papers "blind" - that is, looking at the abstracts without knowing who the speaker is. This has been shown to eliminate the "me and my buddies" nature of many tech conferences, producing more diversity, and more new speakers.

ApacheCon Europe call for papers open
As you are no doubt already aware, we will be holding ApacheCon in Seville, Spain, the week of November 14th, 2016. The call for papers (CFP) for this event is now open, and will remain open until September 9th. The event is divided into two parts, each with its own CFP. The first part of the event, called Apache Big Data, focuses on Big Data projects and related technologies. Website: http://events.linuxfoundation.org/events/apache-big-data-europe CFP: http://events.linuxfoundation.org/events/apache-big-data-europe/program/cfp The second part, called ApacheCon Europe, focuses on the Apache Software Foundation as a whole, covering all projects, community issues, governance, and so on. Website: http://events.linuxfoundation.org/events/apachecon-europe CFP: http://events.linuxfoundation.org/events/apachecon-europe/program/cfp ApacheCon is the official conference of the Apache Software Foundation, and is the best place to meet members of your project and other ASF projects, and strengthen your project's community.

[ANNOUNCE] CFP open for ApacheCon North America 2016
Community growth starts by talking with those interested in your project. ApacheCon North America is coming, are you? We are delighted to announce that the Call For Presentations (CFP) is now open for ApacheCon North America. You can submit your proposed sessions at http://events.linuxfoundation.org/events/apache-big-data-north-america/program/cfp for big data talks and http://events.linuxfoundation.org/events/apachecon-north-america/program/cfp for all other topics. ApacheCon North America will be held in Vancouver, Canada, May 9-13th 2016. ApacheCon has been running every year since 2000, and is the place to build your project communities. While we will consider individual talks we prefer to see related sessions that are likely to draw users and community members. When submitting your talk work with your project community and with related communities to come up with a full program that will walk attendees through the basics and on into mastery of your project in example use cases. Content that introduces what's new in your latest release is also of particular interest, especially when it builds upon existing well know application models. The goal should be to showcase your project in ways that will attract participants and encourage engagement in your community, Please remember to involve your whole project community (user and dev lists) when building content. This is your chance to create a project specific event within the broader ApacheCon conference. Content at ApacheCon North America will be cross-promoted as mini-conferences, such as ApacheCon Big Data, and ApacheCon Mobile, so be sure to indicate which larger category your proposed sessions fit into. Finally, please plan to attend ApacheCon, even if you're not proposing a talk. The biggest value of the event is community building, and we count on you to make it a place where your project community is likely to congregate, not just for the technical content in sessions, but for hackathons, project summits, and good old fashioned face-to-face networking. -- rbo...@apache.org http://apache.org/ - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Some Tapestry infection questions

I am on holidays, and trying to use some Tapestry awesome features, as the
inyection.
But I do not understand some issues, and cannot find the answer in the wiki or
somewhere, to the info is not enough clear for me, sorry.
This is very simple. In the Java part of a page I want to inject the DAO, so I
use this code:
@Inject
private IAplicacionesDAO appDAO;
To have this code running I need to add the service implementation via
AppModule and bind:
public static void bind(ServiceBinder binder)
{
binder.bind(IAplicacionesDAO.class,AplicacionesDAO.class);
Two questions:
a) if I add a constructor to the first class, I have an error:
Class com.earroyoron.pages.VerAplicaciones was not transformed for use as a
component; this can happen if it is an interface, or was not in a package
subject to component transformation
and in the documentation I read the constructor was needed! But without it
works and with it I have an error….
A constructor should not be used in a Page or Component class. Tapestry
does a lot of work behind the scenes when deployed to transform these
classes you write so they function nicely. Read up on the page
lifecycle: http://tapestry.apache.org/page-life-cycle.html
I assume there is some initialization you would like to do on your page
when it is rendered and displayed (which you may have thought belonged
in a constructor), for this you would implement one of the render
lifecycle methods. http://tapestry.apache.org/component-rendering.html
For example
@BeginRender
public void loadUser(){
userId = 1;
appDAO.loadUser(userId);
}
b) Cannot Tapestry find the service without the bind? The infection in the DAO
to use Hibernate does not need to say nothing to Tapestry, it works without any
extra configuration in module.
You will need to do the binding so it can auto-bind your service for
you. You could alternately write a build method to build the service
yourself, but that would be more work and I'm assuming is not what you
wanted. http://tapestry.apache.org/defining-tapestry-ioc-services.html
Thank you in advance, when I learn I promise to help the newbies!

Re: Conversion from 5.1 to 5.2
Just wanted to comment that I'm having very similar issues with an application that I upgraded the production version from 5.1 to 5.2. The 5.1 app ran fine indefinitely with no issues. After the upgrade it took about 1.5 days for the app to crash due to running out of PermGen space (at that point PermGen was not being tuned at all via JVM properties). After restarting it was stable for a few days, then another restart and it crashed in 1 day. This behavior was never observed on a demo machine running the same app with a very long uptime (months). The only differences between the apps are the database connected to and the number of users on the system over time. No real resolution to provide yet nor am I even sure whether this is inherently Tapestry or some private code issue, but I'll be watching this thread and comment if I find anything out related. -Rich On 06/28/2011 12:16 PM, Norman Franke wrote: On Jun 24, 2011, at 7:28 PM, Kalle Korhonen wrote: On Fri, Jun 24, 2011 at 3:33 PM, Norman Franke wrote: After I had everything working pretty well, I put it onto the production server where it ran for a few hours and then died with a PermGen exception. Previously, my app would run for months with the 64 MB of PermGen allocated to servers by default. Now, after upgrading to 5.2.5 it wouldn't run for more than a few hours at 128 MB. I ended up setting it to 512 MB, but that just seems outrageous. Is this normal to require 8x PermGen? I haven't made any other change to my app, just those required to upgrade. Good post, thanks for insights. As for the permgen usage, perhaps it's not normal, but expected and even documented. At 250 pages, your web application is likely bigger than a typical Tapestry app and permgen consumption correlates with the size of the web app. However, in return for higher permgen usage you'll have lower heap consumption, so you'll get better scalability. What's the max you are allocating to the JVM (the -Xmx) and have you tried finding a lower setting that would still work? Permgen usage is for the whole JVM and no more will be required even if you see increase in traffic, unlike in T5.1 case with page pool. Since you have an internal app with fairly predictable traffic pattern and scalability requirements it may not matter for you, but for the common case it's a win with only minor disadvantages (memory is cheap). I'm allocating 768MB for the heap. I haven't tried lower, but jconsole indicates I'm using no more than 80 MB. So I'm a but puzzled at how it exceeded 128 MB. Perhaps when it threw an exception while I was getting some of the conversion issues resolved?

Re: Tapestry Remembers which page to navigate after User Logs in ?
It might help to know the structure by which you control login and
navigation inside the authorized portion of your application.
In my case, all the login forms explicitly return the Overview page :
public onSuccessFromForm(){
// Login validation
return overview;
}
@InjectPage
private Overview overview;
Is there some structure to your application that prevents this from
being a usable pattern?

Re: Safari , DOM 12 Exception, core.js
On 06/14/2011 02:33 PM, Howard Lewis Ship wrote: Is is just one specific field that fails? Perhaps there's something odd about the field's name (the way naming a Form field "submit" can cause grief ... something Tapestry won't even try to do now). This code has changed in 5.3 recently, to defer the lookup until an error actually needs to be displayed. Hmm, interesting point. The first times it was failing on a field named 'name'. That went away when I overrode the property block of the name field in the BeanEditForm (which had been implicit due to t:include directive) to explicitly declare the label and textfield, even though they were still set to 'name'. That behavior was what set off a '!' in my head about the whole thing, followed by the error jumping to a different field. The new field it moved to was 'id', which already had a property block override written. When I renamed the t:id for the textfield for the id field to 'tid', this error went away. So in this case, it did seem to be a result of a name causing grief. What worries me is that these are field names used conventionally across my entity objects. I'd not expect an entity field's name to trigger browser side effects. The workaround seems to be writing property overrides for every form related to an entity object with these names, or refactoring all the entity objects. I suppose I can do one of the two for the time being, but I am curious as to some kind of resolution. It's hard from a developer's standpoint to infer that an entity field's name is going to circumstantially break an internal Component's behavior.

Safari , DOM 12 Exception, core.js
Hi,
an issue has recently been brought to my attention by QA, and I'm trying
to unravel what is at play here.
The core of the problem is that I have a form with validation on a page,
and when this page is loaded in Safari (5.0.2), the error console
appears at the top saying that the TapestryInitializer.validate method
failed due to DOM Exception 12 syntax error on the validation hash built
by Tapestry.
After thorough debugging, I isolated the issue to a section of code from
core.js, the code on line 7723 is failing with the DOM Exception 12
error. More specifically, it is the down method that fails when it calls
findElements and the line 3301 fails in that, when calling the
root.querySelectorAll(e) method. The value of e here is the same as
selector variable except there is '#[object HTMLInputElement] ' appended
to the front
An example of the selector passed into the down method when it fails.
selector = "label[for='name']"
e = "#[object HTMLInputElement] label[for='name']"
Has anyone encountered something similar before and found a way to deal
with it? I've gotten pretty far in uncovering the issue, but I'm running
out of ideas as to a remedy. The validation fails on the page as a
result, which QA is deeming unacceptable. Strangely enough, I never
reproduced this bug in FireFox, Chrome, or IE at any point.
Below is the Associated Javascript.

Rich

I'm sorry, I overlooked the only place user is set. Having been using
Tapestry since 5.0.5, almost four years ago, I'd say @SessionState
works as it should. Your code uses too much side-effects for my taste.
And I can't see the declarations of the username and password variables.
I'd have to say there is too much going on as well as omitted for an
outside observer to really help much more than the suggestions that have
been made by several of us to follow Tapestry standard practices
The best recommendation I could make it to make a much more simplified
version, in separate pages perhaps, where all that happens is a login
page -> authenticate user and establish session state -> display links
depending on user type -> provide log out
Strip out any other logic like the fixtures, etc.
Here's how I might approach it (TML pages left out)
Login page class:
public class Login {
@InjectPage
private userIndex index;
@Inject
private UserDAO udao;
@Component
private Form login;
@Component
private TextField uname;
@Component
private PasswordField pw;
@Property
private String username;
@Property
private String password;
public onSuccessFromLogin(){
if(udao.validateUser( username, password )){
return index.initialize( username );
}else{
login.recordError(uname, "User failed to validate!");
return null;
}
}
}
UserIndex page class:
public class UserIndex {
@SessionState(create=false)
private User user;
public Object initialize(String username){
user = udao.read(username);
return this;
}
@Persist @Property
private Boolean adminUser;
@SetupRender
public void verifyPermissions(){
if(adminUser == null && user != null &&
"Admin".equalsIgnoreCase( user.getUserType() )){
adminUser = true;
}
adminUser = false;
}
@Component
private EventLink logout;
@Inject
private Request req;
@InjectPage
private Login login;
public Object onLogout(){
user = null;
Session session = req.getSession(false);
if(session != null)
session.invalidate();
return login;
}
}
UserDAO interface class:
public interface UserDAO {
public User read(String username);
public boolean validate(String username, String password);
}
UserDAOImpl service class:
public class UserDAOImpl implements UserDAO {
public User read(String username){
User user = null;
Handler handler = new Handler();
Connection conn = handler.getConnection();
PreparedStatement prep;
String read = "Select * from users WHERE username = ?";
prep = conn.prepareStatement( read );

Re: how can I clear the page context?
You can use the public String onPassivate() function in a Page class to
alter the context URL posted to the client browser.
For example, I like to use it to beautify the URL so its not the more
code-y page name it normally would be, and also to mask page names from
the user so they cannot violate permissions (I do keep track of their
current page somehow so a refresh doesn't break things for them).
String onPassivate(){
//strip the package prefix and the page class suffix
return selectedComponent.replaceFirst("admin/",
"").replaceFirst("Tab", "");
}
Hope that helps,
Rich

Re: how to make tapestry ignore processing some paths
Contributions and such should be in the Module class, typically
AppModule. I believe that was omitted from that code excerpt because the
rest of the page was in the context of the Module class.

X-UA-Compatible & IE 9
Hi, has anyone else had trouble with getting the X-UA-Compatible meta tag working in IE9 with Tapestry? I have verified that my rendered HTML page has the tag in the element, but going into Developer Tools it says the Document Mode for the page is not the one I set it to. The reason I mention it on the list is the following from http://msdn.microsoft.com/library/cc288325%28VS.85%29.aspx#SetMode : The |X-UA-Compatible| header is not case sensitive; however, it must appear in the header of the webpage (the HEAD section <http://msdn.microsoft.com/en-us/library/ms535252%28v=VS.85%29.aspx>) before all other elements except for the title <http://msdn.microsoft.com/en-us/library/ms535910%28v=VS.85%29.aspx> element and other *meta* elements. In the rendered HTML, it seems Tapestry places all of the script and stylesheet link tags ahead of the meta and title tags I have defined in my Layout.tml file. Following the above excerpt, this seems to break the rule mentioned about X-UA-Compatible needing to be before all other elements except for the title and other meta elements. I'm trying to force IE8 Document Mode so the Scriptaculous Drag-Drop library will work (does not seem to in IE9). http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> http://www.w3.org/1999/xhtml";> http://localhost:8080/mparking/assets/1.0/stack/en/core.js</a>>"type="text/javascript"> http://localhost:8080/mparking/assets/1.0/core/scriptaculous_1_8_2/dragdrop.js</a>>"type="text/javascript"> http://localhost:8080/mparking/assets/1.0/ctx/scripts/droppableContent.js</a>>"type="text/javascript"> http://localhost:8080/mparking/assets/1.0/chenillekit/components/datetimefield/datepicker.js</a>>"type="text/javascript"> http://localhost:8080/mparking/assets/1.0/chenillekit/components/datetimefield/datepicker_lang.js</a>>"type="text/javascript"> http://localhost:8080/mparking/assets/1.0/chenillekit/prototype-base-extensions.js</a>>"type="text/javascript"> http://localhost:8080/mparking/assets/1.0/chenillekit/prototype-date-extensions.js</a>>"type="text/javascript"> http://localhost:8080/mparking/assets/1.0/core/default.css>"> http://localhost:8080/mparking/assets/1.0/core/tapestry-console.css>"> http://localhost:8080/mparking/assets/1.0/ctx/layout/main.css>"> http://localhost:8080/mparking/assets/1.0/chenillekit/components/datetimefield/datepicker.css>"> Application Thanks, Rich - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Updating only specific divs in Zone update
Thanks, I suppose I should have responded after Thiago mentioned the
MultiZoneUpdate a few days back, which did solve the problem for me.
In my case, I have each Component using the triggerEvent method of
Component Resources with a Callback to return the proper
MultiZoneUpdate. I guess it was hard for me to conceptually understand
why I'd need a MultiZoneUpdate to update just a single Zone in the way I
wanted, but it works.
Component
public Object returnZone(){
final Object[] returnObject = new Object[]{null};
Object[] context = new Object[]{zone};
cr.triggerEvent("TriggerZoneUpdate",
context,
new ComponentEventCallback() {
public boolean handleResult(final Object result) {
if (result != null) {
returnObject[0] = result;
}
return result != null;
}
});
return returnObject[0];
}
Containing Page
public Object onTriggerZoneUpdate(Zone zoneForUpdate){
return new MultiZoneUpdate(zoneForUpdate.getClientId(),
zoneForUpdate);
}

Re: Hyperlink not becoming hyperlink
If I understand you correctly, you have some information stored in a field of your entity that is HTML mark-up for a hyperlink. For example, a beanedit for the entity class Reference which has a field String website which for this entry has an html link like "href="somesite.com">Some Site". If you want that to display as markup and not text, you would use the t:value="entity.website" /> which will output it as HTML for you. You may need to override the column to insert this into the TML, the documentation for beanedit should make it clear how to do that if you don't know how.

Updating only specific divs in Zone update
Hi, I'm trying to put together an interactive page with multiple components, where each component can go through event/actions. For example, two components might be account details and reports. In account details the initial view is a display of your basic fields and their values, but if you select an Edit button, the component will change to display a bean edit form. The challenge I am facing is, when the Edit button is selected, to only update the display of the account details component and not alter the display of the rest of the page. At the moment, I have all of the components contained on the page in a single Zone. From each component I use event callbacks to call a method on the containing Page that will return the zone for the component to update in events/actions. This does not accomplish what I want, as each update call to the zone.getBody() will re-render all of the components at once, not just the account details. Alternately, I tried writing a self-contained zone within each component, but when I return that on event/action methods from a component, it then replaces the rendering of the page with an updated rendering of just that component. I have read about the 't-zone-update' css-class that can be used on a DIV within a Zone to isolate the content that actually gets updated, but I can't see how that will get me to where I want. Any guidance would be much appreciated. Thanks, Rich - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Using JavascriptSupport addInitializerCall
Hi,
I'm trying to leverage some of scriptaculous in a new application I'm
working on. I've got the @Import worked out for including the modules of
scriptaculous I want, but I'm having a hard time grasping how to create
and use some Javascript libraries I create in my pages.
The first simple step I wanted to take was to make a standard
always a Droppable using my Layout page. I made a JS file that has a
basic function to add this div to the Droppables, but I'm not sure how
to get it to run when the page initializes, Firebug debugging is
verifying it does not get called, but I cannot figure it out beyond that.
I tried the following:
@Import(stylesheet="context:layout/main.css",library={"${tapestry.scriptaculous}/dragdrop.js","${tapestry.scriptaculous}/effects.js","context:scripts/droppableContent.js"})
public class Layout {
@Inject
private JavaScriptSupport jsl;
public void setupRender(){
jsl.addInitializerCall("createDroppable()",""); //Make the
Right Content area always droppable
}
}
droppableContent.js:
function createDroppable() {
Droppables.add('rightContent');
alert('added RightContent to droppables');
}

Re: Absolute Paths in Tapestry 5.2.5
We faced problems with the root and app contexts using HTTPD/Apache in
front of a Servlet Container as well at my company. Our solution was as
follows, all in HTTPD. I thought I'd post this in case you find it
useful. You will probably be interested in the lines from ssl.conf (if
you don't use HTTPS then put in the httpd.conf). If you run more than
just the myApp on the server, you'd need a RewriteCond(s) to exempt your
other apps/pages from the rewrite:
httpd.conf (forces HTTPS and maps to the servlet port on requests to the
app context):
RewriteEngine On
RewriteCond %{HTTPS} "off"
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
ProxyRequests Off
Order deny,allow
Allow from all
ProxyPass /myApp http://localhost:8080/myApp
ProxyPassReverse /myApp http://localhost:8080/myApp
ssl.conf (maps requests not to the app, such as root, to the app context):
RewriteEngine On
RewriteRule !^/myApp https://%{HTTP_HOST}/myApp%{REQUEST_URI}

solved the problem (as it does include that header) and is easier to use
anyway. Thanks for the tip.

Sounds like tapestry isn't detecting that you are doing XHR. It's
detected based on an HTTP header "X-Requested-With" set to
"XMLHttpRequest". I believe this is supplied by jquery and prototype,
not the base object provided by the browser.

Generating popup window after form success
Hi, I'm wondering if there is a good strategy to create a popup window after a successful form submit. The concept here is to popup a Voucher/Coupon window for the user if they complete a successful purchase. I've researched the basics of the concept in terms of HTML forms. You can run some Javascript to open a new window on submission of an HTML form. I'd like to be able to limit this functionality to only occur if the transaction is successful, in other words after the onSuccess method has run. Is there any means to fire javascript at this stage before a page refresh, or should I be looking rather at persisted fields and conditionally executing the javascript on page rending after the onSuccess method invokes a re-render of the page? Looking at the Event constants in the tapestry.js, I didn't immediately see an event beyond prepare/validate for forms that I might observe.

Why don't you use onPrepare() instead of onPrepareForRender()?
Same result, unfortunately. I switched to onPrepareForRender eventually
because onPrepare gets called 2-3 times during the page lifecycle while
onPrepareForRender only once. It didn't break anything back in 5.1.0.15
so it seemed like a good idea. I wanted to avoid extra DB calls and
array/String parsing. On another note, I'm not sure whether this problem
even relates to the @Environmental object at all, but I did figure I'd
mention it before just in case.
Anyway, here is what is happening:
@Property @Persist

@Persist @Property
private ThirdParty tp2;
@Persist
private ThirdParty tp3;
public void onPrepare(){
ThirdParty tp = tpdao.read( id.getId() );
// perform field parsing for overridden BeanEditForm blocks
ThirdParty tp2 = tp.clone();
ThirdParty tp3 = tp.clone();
log.debug("In onPrepare: tp = " + tp);
}
public void afterRender(){
log.debug("tp: " + tp + "\n tp2: " + tp2 + "\n tp3: " + tp3);

TML:
Results:
In onPrepare: tp = person; name = person
In onPrepare: tp = person; name = person
tp: id = person; name = person
tp2: id = null; name = null
tp3: id = person; name = person

In trying to mentally recall the justification, I believe the intent is that there is a two-way relationship on the @Environmental PageId id between the container page and the 'subpage'. The subpage term here means that there is the container page with the Grid, and then the subordinate page (loaded via Delegate in container) with the BeanEditForm. By two-way relationship, I mean that the GridPage can manipulate the PageId so that a SubPage can load the correct Entity, and going the other way, the SubPage can reset the PageId in the environment in the event that the user deletes the Entity so the GridPage is aware. Maybe I just need to completely re-evaluate my approach here, perhaps my prior implementation worked by miracle rather than design (I've been forced to learn and seriously develop Tapestry concurrently. Component-driven design over Page-driven design wasn't quite in my repertoire back in August). Before I invest time into that though, I want to verify that there isn't some easy adjustment to my existing code to restore functionality. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
BeanEditForm: What's happening to my object parameter?
Hi,
I upgraded my application to 5.2.4 and everything seemed great, but I
eventually noticed some weird behavior regarding some functionality that
previously worked in my application.
I have a page that displays Entities in a Grid. Each row has a link that
triggers an event with the context of the given entity ID. At this
point, the page stores the id in a persisted Object called PageId, and
sets a boolean to conditionally delegate/render a sub-page in the
template. In @BeginRender, the PageId is pushed into the environment.
The sub-page provides a BeanEditForm for the given Entity object so a
user can update information.
The sub-page uses @Environmental on a PageId object to grab the one
pushed on the stack from the Grid page. In onPrepareForRender, an Entity
object is loaded from the DB based on the value in the PageId.
Everything is good so far. The Entity object is @Property and @Persist
annotated. At the end of the onPrepareForRender method, the Entity is
set properly. However, it seems to get de-referenced at some point
between that method and AfterRender. I put a debug message in
AfterRender and the entity object is no longer referencing the expected
values. Strangely enough, if I define @Persist Entity entity2 and write
entity2 = entity.clone() in the onPrepareForRender method, in
AfterRender, entity2 is still the expected Entity object...
After some further prodding, I found out that whichever entity object is
set as the object parameter of the BeanEditForm is being re-initialized
as if it was assigned = new Entity(). This is breaking my page because I
have been using the entity object to 'initialize' the BeanEditForm
fields to the stored values of the entity. Since the entity ends up
re-initialized during rendering, none of the previously stored fields
are available for a user to see and edit.
What is happening to the entity object, I thought BeanEditForm was
supposed to use it if it was an initialized property (enforced in the
container in a "prepare" event)? The first time the Entity link is
clicked on the GridPage, the entity object ends up null. The second time
as well. The third time, it displays whatever the previous link should
have displayed and continues in this fashion indefinitely. I'd assume I
must have some flawed logic here somewhere, but it is a bit baffling
that it used to work in 5.1.
Simplified code example:
GridPage.java
@Inject
private Environment env;
@Persist
private String subPage;
@Persist @Property
private PageId id;
@Persist @Property
private boolean subtabSelect;
public Object onActionFromDetailsLink(String cid){
subtabSelect = true;
this.subPage = DETAILS_TAB;
id = new PageId(cid);
debug("DetailsLink clicked. SubPageId set to " + this.subPage);
...
}
@BeginRender
public void pushPageId(){
debug("Loaded ViewTPTab and SubPageId = " + this.id);
env.push(PageId.class, id);
}
@AfterRender
public void popPageId(){
this.id = env.pop(PageId.class);
}
DetailsTab.java:
@Environmental
private PageId id;
@Inject
private Environment env;
@Property @Persist
private ThirdParty tp;
@Persist
private ThirdParty tp2;
@Inject
private TPDAO tpdao;
public void onPrepareForRender(){
tp = (ThirdParty) tpdao.read(id.getId());
/* pull some info from the tp object, parse and place
into Persisted fields. These fields are the only ones displayed properly
in the BeanEditForm. BeanEditForm is referencing the tp object. */
tp2 = tp.clone();
debug("In onPrepareForRender of DetailsTab. Loaded ::"+tp+"::
from DB");
}
public void afterRender(){
debug("In afterRender... the TP object is : " + tp ); //tp is null
debug("... tp2 : " + tp2); //tp2 = tpdao.read(id.getId())
}
void onPrepareForSubmit(){
env.push(PageId.class, heldId); //push back into environment on
submit from BeanEditForm
}

Re: 5.1 : Available pages downgrade
Thanks for the replies so far, they have been helpful. I will be looking into both the application server's maintenance of the /tmp folder - where it does seem Jetty is unpacking the WAR - as well as the memory usage of the application and optimizations for that. The production version is frozen at 5.1.0.15 unfortunately, but I recently begun development on the next release version. That, coinciding with the release of ChenilleKit for 5.2.4, has allowed me to successfully upgrade the next version to 5.2.4, which I'm very excited about.

Apparently Jetty in some cases shuts down the application in order to keep the container running, after which you'd see the behavior you described. Adjust jvm settings and allocate more memory to your process. Allocate enough until the whole process dies (if you are on Linux platform - especially virtualized with no swap space, the OOM killer will shut down the JVM way before your process consumes all of the available RAM). Then investigate if any of your forms are reserving a high amount of memory, possibly play with other JVM settings and *if* you are sending a lot of gzipped data, turn gzipping off and see if it makes a difference.

Hi Rich
Thanks. I understood the implementation of listener but i was looking at a
way to integrate it so that all URL's in app gets modified. I understand
that in app module we can plugin any service. Assume i have a impl class
implementing the listener interface, how will i integrate it into existing
application so that all URL's have a dynamic parameter, say system time in
milliseconds appended to the url.
Referencing these lines from ClientPersistentFieldStorageImpl.java:
135 public void updateLink(Link link)
136 {
137 refreshClientData();
138
139 if (clientData != null) link.addParameter(PARAMETER_NAME, clientData);
140 }
You can see that the Link object has an addParameter function. You
should be able to use this to add the system time to the URL as a
parameter, from my understanding. Since you understand the
implementation of listener, then that should be pretty simple.
It seems the last challenge you are facing is how you should setup your
implementation of the listener in the Module so it will be used on link
creation. That is a little bit beyond my scope of knowledge here, so
I'll defer that answer to someone else.
The reason am trying to add the system time is to ensure that everytime a
dynamic value is appended to url and hence proxy server wont cache and show
me stale data which is currently happening.
Thanks

Re: Grid Header Override and Sorting
Apologies for the rambling here. It occurred to me that I could
implement the Link class to return in the event handler. So, I made an
implementation that will return a URI to the grid.columns:sort event as
stated, and everything works nicely.
It still feels like a dirty approach though, if anyone agrees and can
point me towards a more conceptually sound implementation strategy, I'm
all ears.

Object[] ctx = new Object[]{ property };
cr.triggerEvent("sort",

new ComponentEventCallback() {

result) {
if (result != null) {
returnObject[0] = result;
}
return result != null;

//Changes a @Persist enum that controls a switch for returning

getNextSortState();
return returnObject[0];

Alternately, I'm looking at GridColumns and wonder if it is possible
to extend that Component. I'm unsure of how I would use it with a
grid though.
Worst-case scenario I'm imagining is writing an EventLink per Header

messy and like a lot of work, though. I can't think of how that could

Re: tapestry-upload and zones?
Looking through it seems like some browsers (Firefox 3 at the least)
have started working file uploads into their APIs so they can be used in
AJAX, but I don't believe the cross-browser coverage for that is good
enough yet.
I was reading into the IFrame solution when I happened upon a comment
from someone saying you can return a 204 No Content HTTP Response to
prevent a page refresh. Preventing a page refresh would be good enough
for my page to continue otherwise functioning asynchronously while still
allowing for file uploads.
I was able to implement this. I took the upload component out of the
AJAX form and created a separate form for it in the block. This form
calls an onSuccess method that handles the UploadedFile and then returns
a NoContentStreamResponse I wrote up:
public class NoContentStreamResponse implements StreamResponse {
@Override
public String getContentType() {
return "text/plain";
}
@Override
public InputStream getStream() throws IOException {
return new ByteArrayInputStream(new byte[]{});
}
@Override
public void prepareResponse(Response resp) {
resp.setStatus(204);
resp.setContentLength(0);
}
}
So while it is not exactly asynchronous, it does prevent page refresh
(which for me was the main point anyway, avoiding the page render
life-cycle), avoids using an i-frame and the extra code wiring to make
that work, and more importantly it works. Thought I'd share it in case
anyone else comes across a situation similar to mine.

Re: JasperReports integration
How are you running your webapp. Maven and mvn jetty:run, deployed into some servlet, something else? The answer most likely depends on your answer here. If using Maven, you add the jars as a dependency in the pom.xml like: jasperreports-local jasperreports-local 3.5.0 Otherwise, look up how to add dependencies to your classpath for your servlet container.

Re: Uploading then displaying Images
Thanks everyone for the responses so far, conceptually I think this is
coming together for me.
So, I'm glad the context path was not a good idea, it felt dirty from
the beginning. Avoiding that, there are two main options: use the
database to store/retrieve the images, or use a configured system folder
from where I can load/save files with Java IO.
Regardless of the option chosen there, the image file will be captured
as an InputStream and returned as a StreamResponse in some form to a
page/component.
As far as linking the StreamResponse to an HTML IMG tag, I believe I
understand the various options presented here.
LLTYK suggests using an EventLink. I was looking through my code and
found a Captcha implementation I have using a propertyExpression in the
TML on the src attribute of to reference a getImageLink function
that returns ComponentResources.createActionLink("image",null). Then
there is an onImage() action handler method that returns a
StreamResponse. I understand this is ActionLink and not EventLink, but I
think the concept must be nearly identical.
Alternately, Thiago is suggesting that instead of using
ComponentResources to generate an ActionLink or EventLink, it may be
easier to create a seperate Page that handles returning just a
StreamResponse. In that case the EventLink can be replaced with a
PageLink and using an activation context the ID for the Image can be
passed to the Page so it can load the Image, build the StreamResponse,
and return it.
<30 minutes later> Okay, the PageLink works out, great! I can see the
biggest issue I was having was setting up the src attribute for IMG
correctly. I was stuck thinking it was either the URL to the context
path or the StreamResponse itself, rather than a link to an event or
page that returns the StreamResponse.
Thanks,
Rich

I haven't mentioned it because my preferred approach is to create a
page just for returning StreamResponses. It's more reusable, as it can
be used to serve images for any page, while an event must be only used
inside a give page.

Uploading then displaying Images
Hi, I think I've run into a conceptual understanding roadblock in trying to setup uploading then displaying of images in my application. I've got the uploading part working so far, although since my application is deployed as a WAR, the files upload to a system folder. That works alright, but might be a concern regarding the subsequent displaying. I wrote up a service that can manage these images as Image or File object, and I wrote up an ImageStreamResponse class with its inputStream coming from the Image's outputStream. The service can generate the ImageStreamResponse from a filename, which I store in the database. I had read this thread http://tapestry.1045711.n5.nabble.com/How-to-display-Blob-byte-array-image-td2436148.html along with other information regarding uploading/displaying images.

Re: Label not displaying it's body
Are you decorating the label or otherwise making use of it as a
component, or just using it to display? If you want to give your own
value for the label text disaply, why not just use an HTML label like
${myValueHere}.
I'm not sure what is going on with your code example because it has a
lot of typos, if that was because your email sent in HTML the first
time, send it in plain text. I'd at least expect the for=userName to be
for="userName" and t:type="TextField" instead of t:type="TextFieldd" for
it to be valid XHTML and a valid invisibly instrumented component.

Re: org.apache.tapestry5.runtime.ComponentEventException
If you want it to return a String, do something like this. Also,
@SessionState would not be necessary in a class like this. The
@SessionState in your page class(es) will maintain the object for you.
public class User {
private String user_id;
public User getUser_id() { return user_id; }
public void setUser_id(String user_id){ this.user_id = user_id; }
public void setUser(User user){ this.user_id = user.getUser_id; }
}
If you haven't already done so at login or something along those lines
before a user gets to the page in question, you'll want to do something
like the following (maybe in onActivate rather, but I don't know your
application) otherwise it would make sense that the @SessionState User
user_id is null.
@SetupRender
void initUser(){
if(user_id == null || user_id.getUser_id() == null){
user_id = new User();
user_id.setUser_id( /* whatever the user_id String would be
that you need to set */ );
}
}
Yes I have a method like that but it keep's returning null, my user class:
//These were originally strings but changed in an effort to get
working
@SessionState
private User user_id;
public User getUser_id() {
return user_id;
}
public void setUser_id(User user_id) {
this.user_id = user_id;
}
then the in my page:
@SessionState
private User user;
@Property
private String user_id;
public User getUser() {

}

Me neither, I suppose I expected that simply using the recordError would
have my page functioning the same way the POST would without AJAX, but
that's a bit naive
I added a handler for failure and returned the same block back
and it seems to do the right thing. Is the form supposed to just send
back the errors if it fails?
Block onFailure() {
log.debug("Failed form post");
return resources.findBlock("triggerPrice");
}
Yes, the form is supposed to send back just errors if it fails. I think
using onFailure is my best solution at this point, I didn't realize I
could catch onFailure and return a Block/Page/etc, I think I had become
reliant on using onValidate and recordError to do as much for me in the
rest of the pages I wrote.
I tried the onFailure returning the findBlock("triggerPrice") from
ComponentResources as well as using blockZone.getBody(). In both of
those cases, the page re-rendered with the Tapestry red X beside the
form input field in error, but the Validation Bubbles did not appear.
I've decided to save myself some trouble and use onFailure to return the
page by String name so the full reload occurs and the Validation Bubbles
show.
Thanks for the help,

Re: [5.1] recordError for Forms in Blocks
Hmm, no luck. I checked the error console and nothing came up. Looked at
the Request and Response sent in Firebug console, the Response is 200 OK
and the response body is {}. Threw in a handful of breakpoints in
Tapestry.js in places that seemed relevant to the Validation Bubbles but
never saw anything too interesting come up. I'd willingly look deeper,
but I'm not too sure what I'm looking for at this point.

Re: Select with zone failing intermittently
I can't say with any certainty this is your problem, but the one time I
was having issues with an AJAX request being dumped and never showing up
server side there was a race condition. I had it listening to the click
event of a submit button, and on slower connections the form submit
would beat out the AJAX request to the server. In your case I could see
the Periodic update (assuming its on the same page) creating some sort
of race condition. Worth considering if so.
Here is the link to the thread on this list so you can compare and see
if your code is similar:

I finally avoided the problem by getting rid of the chained selects. I went
back to our older component that does the chaining with simple javascript
(stuffing all the possible selection lists into the html which works okay if
they're not huge), so there's no ajax request on the first select. The
second select does an onchange form submit. Crude and a bit slower but it
works.
In other words it stumped me. Maybe some day someone else will see this

I've been trying to figure out a weird bug today, and before I lose the
night over it I thought I'd ask the list. I'm using the cool new
"chained
select" feature. One Select has a zone, and triggers an
onValueChanged()
method that affects another Select. It works fine on my machine and
when
most users try it. When the first selection changes the server gets the
method call and the zone updates, no problem.
We have a few users in a remote office who access the application
through a
slightly slow connection to a Citrix server. That is, the browser is
actually running here (in the same network as the app server) and the
user
receives only screen updates. Occasionally these users will see that
the
chained selects don't work at all. I've debugged it a little (kinda
difficult since I can't make it happen locally) and the first Select's
method call doesn't happen. I don't think it's only a case of slowness
-- I
waited about ten seconds.
Does this ring any bells? I can't see how the Citrix factor or the
connection speed would have any effect. The app server and browser are
in
the same network. Other requests are working fine; the app has been
running
almost a year. I have a periodic-update ajax request that successfully
makes it to the server for the same user.
So maybe I'm using the new feature incorrectly.
.tml:
Recipients
.java:
private final SelectModel carrierModel = new AbstractSelectModel()
{
// Omitting null-returning getOptionGroups() for simplicity
public List getOptions()
{
List carriers = getModel().getCarriers(); //
sorted by
name
List options =
CollFactory.newList(carriers.size());
for (Company carrier : carriers) {
options.add(new
OptionModelImpl(carrier.getCarrierShortName(), carrier));
}
return options;
}
};
public SelectModel getCarrierModel()
{
return carrierModel;
}
public Object onValueChangedFromCarrierSelect(Company carrier)
{
debug("-- onValueChangedFromCarrierSelect " +
carrier.getCarrierShortName());
selectedCarrier = carrier;
return recipientZone.getBody();
}
To be clear: In the real app, the recipientSelect also has a zone
parameter
to update a third list. I omitted it here because the bug happens
before
that.
The only thing I can see that I'm doing different from the documented
example is, my selects are in the same zone. I'll try splitting them up
and
using a MultiZoneUpdate or some such.
Thanks for any ideas.

I think the issue here is forgetting the event instance and relying only on passing information to the event handler method (in this case, using the context). I fully agree, my answer was convoluted in attempts to reference the broader scope of challenges faced when dealing with the static structure of a component enclosed within a loop. The concept of static structure, given a full understanding, makes the proper use of components in a Loop clear. However, I still think for someone coming to Tapestry it is likely to think of loops in the Java sense where each iteration is fresh (loop-declared objects/variables are unique between iterations, etc). It would be worthwhile to clarify the implications of static structure in loops where users are most likely to confuse a need for dynamic behavior with dynamic structure based on prior experiences with loops. Perhaps I haven't found the right documentation page, but I can't readily find much explanation of static structure and its implications in the Tapestry site documentation on pages where I might expect it.

Re: EventLink URI and loop component
Hi, I believe this is a common stumbling point with Loops in Tapestry and the relation to static structure. Tapestry is able to set distinct component IDs in the first case because there is a definition for each facetbox component in your TML. However, in the version with the loop, there is only one facetbox statically defined in the TML, so it is given one component ID by Tapestry (as it seems one is not explicitly being provided). Think about it from the aspect of connecting to the component(s) from your Page/Component class. If you used @InjectComponent, what would be the difference in referencing your facetbox(es) between using the loop and not? In many cases, people want distinct attributes for a given component defined within a Loop. There is a recent thread ( http://markmail.org/message/uwcpkn5s6k2azrpw ) in the list about making the Zone ID attribute distinct between the actual instances of a component declared within a Loop. I've also seen similar solutions in the list for Client ID and so on. The challenge in your case is I don't believe you can dynamically assign a component ID. I double checked myself just now, and t:id only took a discrete ID (in 5.1.0.5), and was not happy pulling it from a property or other dynamic means. Therefore, the solutions for Zone ID and Client ID being dynamically assigned from a getXXX() property method does not seem viable to port over to Component ID. This leads to Thiago's example of using the EventLink's context parameter. I believe in order to make use of the context parameter here, the concept of the FacetBox will need to change from being the Box of a unique Facet to being a Box that will handle any Facet that is passed in to its context. As a result, instead of the method your EventLink triggers implicitly understanding the Facet it should work with, it will need to explicitly load the Facet from the information in the context parameter. *Aside: I referenced the FAQ page, as well as the Component Reference pages for Loop and AjaxFormLoop on the Tapestry site, but couldn't find any direct mentions of enabling controlled, dynamic attributes for a looped component. It seems this question gets asked enough in one form or another in this list to warrant some attention on one or all of those pages. Specifically in regards to the best practices for giving dynamic values to some attributes, clarifying that the component ID/component itself is going to be static, and detailing the implications of static structure and Loops.

As I have several facets, I need several FacetBoxes: In each facetbox there exists at least one EventLink component which triggers an event in the corresponding facetbox. So far so good, everything works. But know I'd like to make things more generic. I would like to be able to change my facets easily e.g. by defining a list containing all currently available facets. I use a loop component to create just the facets available: I did not change anything else. Now, my EventLink components inside of the facets won't work correctly anymore. The EventLinks created in the _first_ example looked like this: /hits.tabs.facetbox:termselect/ /hits.tabs.facetbox_0:termselect/ /hits.tabs.facetbox_1:termselect/ ... In the _second_ example, the links look like this: /hits.tabs.facetbox:termselect/ /hits.tabs.facetbox:termselect/ /hits.tabs.facetbox:termselect/ ... You will notice that the internal ID identifying the component is gone. As a consequence, the event "termselect" is always triggered in the first facetbox instead of the one defining the EventLink.

Re: Regarding overlay image in tapestry
Hi, still trying to clarify in my head what you are trying to do, but almost all of that functionality would still be HTML using CSS. I'm guessing you are laying a link element over the image element you have (or making the img the CSS background-image of a link element). The only difference with plain old HTML and Tapestry then would be to consider using a pagelink component to build a link to your next Tapestry page. Alternately, if you are going to be making a whole lot of these playbutton image links, you can make your own component that does all the above on its own, and then just include that component as an element in your TML file for the page. -Rich On 02/09/2011 05:13 PM, sarov saravanan wrote: Hi, I am just trying to display a playbutton image over a list of main images, That is you see list of images on a page and each will have a playbutton image over it which on clicking leads to another page.

I have it bind via Prototype to the mouseup event to fire a method that returns via AJAX back to the Page class. I just re-read your original post. Are you canceling the form submit when you handle the mouseup? Ah, no, that seems like the exceedingly logical thing to do though. I had basically set it so the mixin would set the Page variable, so although the form always submitted, it had a line of logic to read the page variable and know when to stop itself and return out before processing DB entities and such. I inserted some simple JS after the ZoneManager call that wastes half a second of time. That seemed to be ample time to allow the ZoneManager update to trigger the event before the form submission. Do you think 500 ms is excessive waiting time here? I'm not sure how you're code works, but instead I'd fix the issue by preventing the form from being submitted when you capture the mouseup, and then do the re-post the form in Javascript when you know it's what needs to get done. Putting in pauses is the kind of workaround that's likely to bite you later when the timing changes again. I seem to recall something like this coming up on the list before, there might be existing code for an ajax enabled confirmation dialog. A quick google didn't find it, but you might have more luck if you're more persistent. Josh Gotcha. I do like the sound of that solution better, albeit it is more complicated (in terms of what I know how to do and don't know how to do). I'm a bit lost as to what I'd need to do to make this happen. I suppose it won't require a ZoneManager update for one thing, since this solution avoids interacting back with the server. Is there a way to hook up the mixin to the Submit so that it can return false for the onsubmit event of the Submit element? That seems like probably the most straightforward solution I can think of to stop the form, unless there's a Tapestry way of canceling the event that calls back to the Page class onPrepare/onSuccess methods. I found this thread ( http://tapestry.1045711.n5.nabble.com/quot-Confirm-quot-mixin-won-t-cancel-when-in-zone-td2436465.html ) which seems similar, but wasn't quite able to parse out the necessary javascript concepts I'd need to get what I'm looking for.

Re: [5.1] Confusing ZoneUpdater behavior
Oh wow, I never thought of that.. so it was racing between triggering the zone event and the form submission then I'm guessing? I tried moving a single breakpoint to the ZoneManager call and then resuming the JS again. That wasn't working in Firebug, the only way was if I stepped past the ZoneManager call before resuming. That was enough for me to believe it was some timing problem. I inserted some simple JS after the ZoneManager call that wastes half a second of time. That seemed to be ample time to allow the ZoneManager update to trigger the event before the form submission. Do you think 500 ms is excessive waiting time here?

Re: Tapestry 5 and W3C HTML Validation
I see some of your points. The W3C one is supposed to be an XHTML validator.. I've run both XHTML 1.0 Strict and XHTML 1.0 Transitional, but I think you're right in saying it doesn't pick up the Tapestry XML namespace. I am, however, validating the final HTML output. I point the url to the page and it loads the page and runs on the generated HTML. The nesting of the tags still seems a valid point, unless I'm still missing something here or writing the tags wrong. If you are interested in seeing what I'm talking about, here is a link to the validation I see: http://validator.w3.org/check?uri=https%3A%2F%2Fwww.moremagicpoints.com%2Fmloyalty%2Findex&charset=%28detect+automatically%29&doctype=Inline&ss=1&outline=1&group=0&user-agent=W3C_Validator%2F1.1 -Rich On 01/04/2011 12:51 PM, Thiago H. de Paula Figueiredo wrote: On Tue, 04 Jan 2011 15:14:00 -0200, Rich M wrote: Hi, Hi!

MarkupWriter element and IE8
Hi,
I noticed strange behavior with Internet Explorer 8 and some
MarkupWriter output into HTML using the element method.
I have the following in my page class:
writer.element("a","href",formEvent,"id","submitPrefs","onclick",
"javascript:setupSubmit(this,'"+(overrideParentPage==null?"":overrideParentPage)+"');");
in FireFox this renders as (when overrideParentPage = OverviewTab):
Save Preferences
This was what I expected.
However, in IE 8 it renders as this:
http://localhost/mloyalty/cai/index/catchoose:savepreferences";>Save Preferences
The issue here being that in IE8 the ' characters got written out as
&'
The setupSubmit script is vital to functionality, anyone have any
insight into this issue?
Thanks,
Rich

Re: MarkupWriter and TML together?
Oh, okay, that works great. Guess I got my mindset too narrow to see that, thanks. One more thing, the FormEventLink that is generated doesn't always play nice. Two scenarios (the Component with the FormEventLink will be called EventComponent): 1. A Page class contains reference to the EventComponent in the TML. The EventLink generated in the HTML builds a proper URI for this page class and everything works. 2. A main Page class delegates a section of its TML to another Page class, which is dynamic. This delegated Page class contains reference to the EventComponent in the TML. The EventLink generated in the HTML builds an incorrect URI for this page class. It builds one referencing the Main Page, while the EventComponent is only known to and a part of the Delegate Page. To solve #2 temporarily, I was able to re-write the URI from the generated EventLink to reference the correct component. First I got it working using new LinkImpl, but since that is an internal class, I opted for a Javascript rewrite instead. I couldn't find any other way of regenerating the link though... Not sure if there is one? Thanks, Rich On 12/22/2010 02:42 PM, Thiago H. de Paula Figueiredo wrote: On Wed, 22 Dec 2010 17:05:22 -0200, Rich M wrote: I suppose this is where I am confused.

The query parameter is pulled from the hidden input field in the enclosing form. The javascript method setupSubmit takes care of converting the value of the hidden input field into the activation context of the URL for the EventLink.

Hmm, I'd tried that several ways, every time the ParameterNames() list
was empty and I couldn't fetch the parameter I was looking for. I tried

There was an additional complication with submitting the HTML form and
the EventLink at the same time. I had thought wrapping the HTML form
submit inside the EventLink might work, but this submits the event twice
it seems.
Here's some code relating to the form and EventLink that might
illuminate things:
w.element("form", "id", "prefForm", "method", "post");
w.element("center");
w.element("input", "type", "hidden", "id", "productsList", "value",
""); //This is the field to pass to Event Handler
w.end();
Link formEvent = cr.createFormEventLink("SavePreferences", new
Object[]{});
w.element("a","href",formEvent,"id","submitPrefs","onclick","javascript:setupSubmit(this);");
w.element("input", "type", "submit", "value",
ms.get("save-rewards-preferences"));
w.end(); //submit
w.end(); //formEventLink

Re: MarkupWriter and TML together?
Whoops, spoke to soon on that Element / Persist strategy. Didn't stop to think that the Element object was completely class side and only would be as up-to-date as it was at declaration. Any changes in the DOM by Javascript don't translate so that doesn't quite work. Wanted to make sure no one ended up trying the same and failing. I don't have the option of using 5.2 at this point, so that seems to leave out @RequestParameter and @ActivationRequestParameter. What might my other options be for passing back the value attribute from an HTML tag to the Component Event method? I've tried using Javascript to manipulate the EventLink's context, but this is really messy. My input value is a comma-separated list and the context complains on nearly any special character I'd like to separate the values with. I ended up getting working functionality by replacing spaces with 'BlAnK' and separating the list with 'SePaRaToR' instead of ','. These two strings look so weird as to avoid any chance someone might actually match them. Feels like a terrible hack to me though, but deadlines are deadlines and it works. Is there anything more elegant that this? I'd surely want to refactor this code ASAP after my deadline. Would an upgrade to 5.2 and using @RequestParameter be the best refactor I could do, or is there another solution, possibly 5.1 compatible?
