Custom field, fckEditor, rendering order
I'm having some trouble with the rendering of a custom field - I'm hoping
someone can give me a steer on the order of interpretation / execution during
rendering.
When I use the T5EasyFCKEditor in a .tml as follows:
textarea t:type=easyfck/fckeditor width=800px height=400px value=xyz
configuration=customConf/
... it works as expected and the textarea is decorated / enhanced. When I try
to use the easyFCK in a custom field however, it renders as a standard
textarea, albeit with the attribute t:type=easyfck/fckeditor.
In the custom field beginRender method I have:
boolean beginRender(MarkupWriter writer) {
.
.
.
} else if (useFCKEditor){
writer.element(textarea,
t:type, easyfck/fckeditor,
name, getControlName(),
id, getClientId(),
width, 800px,
height, 400px,
configuration, customConf);
writer.write(value == null ? null : value.getText());
.
.
.
}
Any ideas on why the second approach doesn't work?
Thanks,
Jim.

Popup PDF
I have a requirement to generate a PDF based on some submitted form data in a 'detail' page, and then pop up the PDF in a new tab/window while at the same time returning from the 'detail' page to a 'summary' page. I don't want to pollute the summary page with any code related to opening the PDF in a new tab/window. The actual PDF is being generated and I can return that as a stream successfully but I'm trying to find out how to return the summary page in the existing tab/window, and also trigger the PDF opening in another tab/window, as effectively I'm trying to generate two server responses for one server request. Can anyone suggest a good way of going about this? Should I put something in the detail page that triggers an actionLink with target=_blank before redirecting to the summary page? Thanks.

RE: Popup PDF
Thanks for the suggestion Richard. One thing I am having difficulty with (I couldn’t see this in your reply) is how to submit the form data required to generate the PDF to the server before launching the PDF using target=blank. Perhaps I am going about this in a wrong-headed way and need to rethink the requirement. I’d welcome any other suggestions if anyone has one. I suppose one approach could be to have a submit button that POSTs the form data, and then redisplay the same page with the submit button hidden and a new actionLink ‘View PDF’ now present but it seems a bit clunky. Regards, Jim. From: Richard Hill [mailto:r...@su3analytics.com] Sent: 08 April 2011 12:26 To: Tapestry users Subject: Re: Popup PDF The simplest way I'm guessing is to have your link that generates/returns the pdf to be a target=_blank as you say. Then in javascript change the window url from the detail url to the summary url. If adding your own js to an actionlink is tricky you could not use an action (or page) link, but do the whole thing in javascript - open a new window with the appropriate url for the pdf, and then load the summary page in the current window. Or maybe a mixin would work if you want to add your own js to an action or page link? Richard.

Hi David,
Apart from the lack of details in your question, this is also hardly a
Tapestry question. You should direct it to the Spring forums instead, but if
this reply helps so be it:
You will need in your applicationContext.xml to define a bean that will
automatically start receiving events (I assume you know how)... I am not
familiar with Spring security, but the API docs are quite clear:
http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframe
work/context/ApplicationListener.html
So code that might have looked something like this in the past:
public void onApplicationEvent(ApplicationEvent applicationEvent)
{
if (applicationEvent instanceof AuthenticationSuccessEvent)
{
AuthenticationSuccessEvent event = (AuthenticationSuccessEvent)
applicationEvent;
UserDetails userDetails = (UserDetails)
event.getAuthentication().getPrincipal();
//notify here now, etc.
}
}
'In theory' (untested of course) can now be replaced by:
public void onApplicationEvent(AuthenticationSuccessEvent successEvent)
{
UserDetails userDetails = (UserDetails)
successEvent.getAuthentication().getPrincipal();
//notify here etc.
}
And thats all?!
Cheers,
Peter

RE: [OT] encoding of properties files
2nd try to get through spam filter... Perhaps the text editor you are using for editing your property files and templates is not character code aware, for instance old versions of Notepad. If you are using Eclipse for editing these files it may be set to auto-detect the character encoding, and if one of the previous developers is using a clashing editor / character encoding, the meta tag in your property files and templates will be directing the browser to decode the characters using a character set that is different to the one actually used to save the content. You can check if the browser rendered content is actually ISO-8859-1 by changing the Firefox setting to the required encoding (View → Character Encoding → Western (ISO-8859-1)) instead of Auto-detect, to see if the relevant characters come out ok, if not, then I would check the editor you are using to edit the files (including history of check-ins by other developers) and make sure it is setting the encoding correctly. Another area that may be relevant is if you have contributed a Servlet Filter, and in its service method you have used setCharacterEncoding(UTF-8) or some other invalid encoding. I use UTF-8 project-wide, ensure my editors are character code aware, and have no problem with special characters.

Thanks for the feedback Donny. The code excerpts are a few taken from
various support classes (not page classes, though they are used throughout
the app including within page classes) with static members / methods grouped
under various contexts (date / number / string utils etc.) The logger is
slf4j (with log4j). The Money / Scalar classes are wrappers for BigDecimal,
to allow money / arithmetic ops with predictable precision. I found a few
instances of Matcher that I think I will bundle into a service. Thanks for

I glanced over it, it looks okay. A few notes:
You didn't give the package name for Logger, Money, or Scalar, so I can't
comment on them, although Log4j's Logger is thread safe, and I would guess
most loggers are.
Pattern is thread safe, but note that Matcher is not.
Yes, it is just a matter of looking through any objects that you initialize
in the Page class, outside of a method. An alternative is to create any
variables you need in setupRender() rather than when you declare them in the
class, only moving them out if they cause poor performance (and checking
that they're thread safe beforehand). My coding style normally is not to
have many objects like that in the page class, instead having them in
services.

RE: Grid with Scroll synchronization + Customization
Also, if your grid is displaying many entities and those entities contains
many eager-loaded relations, you are retrieving a lot of data that may not
be necessary. Perhaps you should consider a view-only entity that is
restricted to the actual displayed columns, and retrieve those entities with
some manual SQL. Other options include setting the result set size
(setMaxResults) and displaying an information message where the result set
is larger than the limit to prompt the user to be more specific in their
search criteria, or using a grid where the pages of results are loaded on
demand, rather than the entire list loaded upon initial display.

Jim.

You could probably remove the TimingFilter that is present in your
AppModule. This service is part of the app that is generated by the
quickstart archetype and serve as an example of how to build and contribute
services. Just comment out the methods buildTimingFilter() and
contributeRequestHandler() (if the timing filter is the only contribution)
and you have 2624 ms gain in you app. :-)

Thanks Thiago for pointing out logger issue. It was really very helpful.
Now, the application takes around 5-6 seconds instead of 12-13 seconds it
was taking before. But still have to figure out why it is taking 5-6
seconds
in Tapestry.
The log says:

I have below method in my AppModule which uses TiminigFilter:

// Each contribution to an ordered configuration has a name, When
necessary,
you may
// set constraints to precisely control the invocation order of the
contributed filter
// within the pipeline.
configuration.add(Timing, filter);
}
Please help me to find out the root cause so that I can resolve this
performance issue.

Can you wrap the grid in a div with fixed height / width and set its overflow css property to both?

RE: Memory creep

Thiago, your suggestion of using VisualVM was very helpful - a very good tool. It looks like Tapestry (at least 5.2.1) is very good at releasing resources - my heap size vs. used heap is consistently bouncing between predictable levels even after running tests 24 hours over a few days.

There are a few user coding errors that can trap objects that should be reclaimed, but you have to work a bit hard to hit those. The biggest memory issue is the heavy use of PermGen space, especially under development. Java is very reticent about GC'ing PermGen, even when you request a GC explicitly.

Memory creep
I'm testing a Tapestry app running under Jetty on Windows using multiple Selenium IDE sessions and have noticed a creep of about 130MB RAM per hour on my java exe when running through a test loop that logs in to the app, runs through some expected user behaviour (some search screens, detail screens, minor amounts of data entry / persistence) and then logs out. Each test loop iteration takes about 40 seconds. Upon log out, the http session is destroyed and I am running six concurrent sessions at the moment. The test script does not vary the entities retrieved from the database so beyond the initial entity caching I would not expect the memory usage to keep increasing, i.e. it should bottom out at some stage. I've found this with T.5.2.0 and also T.5.2.1, and the current JVM I'm using is from jdk1.6.0_21_x64 on Jetty 6.1.18. I'm working my way through different JVMs at the moment to see if there is much of a difference. Given that the entities loaded are the same during the test loops, the HTTP session is destroyed during each loop cycle, and the memory footprint appears to stay at the same level after the tests are stopped, could anyone give any pointers to Tapestry areas to look at to try to identify the cause of the memory creep? Or perhaps this is a JVM / Jetty issue? Having trawled through the list before on related GC issues, I'm using the following JVM settings: -server -Xms1408m -Xmx1536m -XX:MaxPermSize=256m -XX:NewSize=384m -XX:SurvivorRatio=2 With such a noticeable creep (initially approx 650MB with 6 sessions rising to 780MB after 1 hour) reproducible on a dev machine I'm concerned that this app won't make it out of dev unless I can get to the bottom of the problem.

RE: Objects session persistance and validation
I'm not sure if this is relevant to your current problem, but to tell
Tapestry which constructor to use for the bean editor, you should annotate
the default (no args) constructor with @Inject - this will allow the BEF to
create the relevant entity if none if present. Hope this helps.

Subject: Objects session persistance and validation
Hi all,
I'm trying to write simple registration form using beaneditor component.
If I fullfill all reqired fields in the form and submit it - everything
works fine, but if server validation occurs (for example passwords don't
match), then all data is lost and Registration page renders with validation
errors, but without user data (input values).
I think the reason for this behaviour is the initializeNewUser() method,
wich rewrites all data if user field is null. But if I delete this method
from code, tapestry throws exception - User can't be instantiated (tapestry
tries to use constructor with most parameters, which has custom objects, not
only String, Integer, etc). So how can resolve this problem?
Thanks in advance.
My code (some code is token from Tapestry5 Hotel Booking example):
-Registration.java:-
---
public class Registration {
@Property
@Persist(PersistenceConstants.FLASH)
private User user;
@OnEvent(value = EventConstants.PREPARE, component = registerForm)

if (this.user == null) {
this.user = new User();
this.user.setCustomer(new Customer());
} else {
if (this.user.getCustomer() == null) {
this.user.setCustomer(new Customer());
}
}
}

RE: T5 Customize Returned List.
I'm surprised Tapestry didn't complain when you have an annotation @Property
on the item and also a matching explicit getter. In the .tml I think you
should use distinct naming for the source and value arguments as the
behavior might not be what you expect otherwise (T5 is case insensitive in
this area?). Why don't you try:
.java
@Property
private TableSource source;
@Property
private ListTableSource sources;
**no explicit get methods**
.tml
t:loop source=Sources value=source
{source.attribute}
/t:loop
...where attribute is a property with a public getter on the TableSource
class.

Jim.

RE: [T5] Complexity for simple things, where is the documentation?
For your specific use case, displaying the server time on the page, would you not be better off to initialize a value to the current server time upon initial page display, and then use a JS widget to increment/refresh the time field on the client side? This would save a lot of unnecessary network traffic, unless there is a compelling reason to have absolute synchronization between what is displayed and the actual time on the server. The variance would be sub one second with this approach, and you would not require zone updating etc. Regards, Jim. -Original Message- From: iberck [mailto:ibe...@gmail.com] Sent: 16 October 2010 22:30 To: users@tapestry.apache.org Subject: Re: [T5] Complexity for simple things, where is the documentation?

While preparing small showcase app, odd problem came out. When I created domain object with two constructors (first was default NOOP, second one had two parameters string and enum, it was meant for manual initialization only) and tried to use it with beaneditform I received exception that tapestry cannot handle my object creation. After removing parametrized constructor, error disappeared. It's bit odd IMHO. Tapestry should be capable to instantiate objects that have more than one constructor. Also @SessionState behaved weirdly. I was annotating java.util.Date. Error came up if I haven't instantiate object manually. Date has default constructor so Tapestry should be fine with constructing new Date on it's own. Maybe there are some reasons for that kind of behavior, but as I see it those are bugs. Should I create jira ticket for that? Tested on tapestry 5.2.1-snapshot.

RE: PropertyEditContext not available from Environment
Thiago,
Are you saying the I can use t:grid ... overrides=prop:xyz to get around
the problem? Do I just build a list of PropertyOverrides in the page class for
that, and does it override all other overrides that the grid normally provides
by itself - I'm guessing this behavior is not what I want as I just want to
affect rendering for this specific field, t:myCustomComponent
value=bom.property/?
I had started creating my own PropertyEditContext in the component used for my
custom type just in the scenario where it's used in a grid, but was running
into issues with an internal null pointer when I got to validate.render() in my
component's beginRender method.
What I was trying to do was something along the lines of:
boolean pECForGridRequired =
(environment.peek(PropertyEditContext.class) == null);
PropertyEditContext pECForGrid = null;
if (pECForGridRequired){
pECForGrid = createPECForGrid();
environment.push(PropertyEditContext.class, pECForGrid);
}
... and mimicking the way the PEC is created when the component is used in a
beanEditForm. Is this approach wrong-headed?
Regards,
Jim.

I was talking about creating a component that does that, not using this
functionality. :)
By the way, I just remembered about the overrides parameter in Grid.
You'll probably don't need to create another component, just make sure the
overrides provide the edition block instead of the viewing one. Maybe we
could even add a PropertyOverrides implementation that implements that to
Tapestry . . .

RE: PropertyEditContext not available from Environment
Thanks for all your help Thiago. I'm not trying to render all fields in the grid as form fields, just the one from my custom component X that's a property of bom Y, and a selection of other properties of bom Y that are plain Strings, Integers etc., which the grid handles perfectly just using t:param and input fields. I have what I need working by creating a PropertyEditContext in the beginRender method of the custom component whenever it is being rendered as part of a grid, pushing it to the environment, and popping it in the afterRender method. Hopefully this doesn't set off any alarm bells. I like the idea of being able to use the overrides to achieve something similar, though it does put the onus on the developer to make the override available as a property in every page where a relevant grid occurs I think. I'll have a look into it when I'm not so stretched for time. Thanks again.

PropertyEditContext not available from Environment
I have a custom data type that I am displaying / updating successfully in beanDisplays and beanEditForms, after making BeanBlockContributions for edit and display, and also using a CustomPropertyEditor that defers environment.pop(PropertyEditContext.class) until after rendering is complete.

I'm have a NumberFormatBinding service as outlined on this list previously ,to mask numeric fields for display with a format mask ex. t:textField t:id=amount value=amount translate=numberFormat:#,##0.00 / I noticed in T5.2.0 there is an @Translate annotation - rather than using specifying the translator repeatedly in various tml files, is there some way I can name the translator on a bean property, and also pass in the mask to be used? The @Translate annotation appears to just take a 'value' parameter that is the name of the translator. Thanks, Jim.
Enum mask
Tapestry provides a very handy facility for presenting enums as drop down lists for display - is there anything built-in that allows certain values for the enum to be hidden from the generated drop down list? Ex. where a status transition follows a strict order where A can be progressed to B and then to C, but B cannot got back to A, so in the case where an entity is already at status B, I only want to display B and C as options for selection. Similarly if A needs to go to B before C, when an entity has status A, I only want to display A, B rather than A, B, C. Regards, Jim.
RE: Enum mask
Thanks Howard. Is there an easier way, just using a mixin that takes another parameter (ex. a comma separated list of include / exclude list index entries) from the template and in the mixin beginRender etc. performs an op on the model created from the Enum? I was hoping to not have to duplicate the creation of the model from the enum, camel casing it etc. that the existing SelectModel does.

Unfortunately we've got another T5.2 migration issue that I can't figure
out. I wonder if this is to do with the service class reloading added in 5.2
- is there a way of disabling it to check?
I've posted the error trace below, basically a service
(ScholarUniverseSearchEngine) is trying to create a class
(ScholarUniverseResultsList) and failing because there seems to be 2
different versions of the service in different classloaders. It's really
puzzling because this service and class is copied from another that does the
exact same thing and still works okay. I tried running it by deploying a war
to a standalone tomcat, and it's fine. It just seems to be a problem when
running from within Eclipse using runjettyrun. We'll try some more
combinations out, but if anyone can help with this it would be great.

General debugging query
I'm using Eclipse 3.4.1 and debugging with a variety of JVMs from late 1.4s to 1.6+ -I'm finding that the mouseover popups or watch variables frequently evaluate variables as null in, say, some page method, but then if I follow the debugger through to the service / DAO layer I can get a correct value for the variable in a popup / watch - this is ex. a parameter that may be assigned in a page method and then passed to the service layer, and so has not been reassigned between the page and the service method. This is becoming a real PITA - I wasted about 2 hours yesterday scratching my head about why some entity wasn't being set in a page by a BEF as the debugger displayed it as null, when in fact the real problem was down to a database issue, and BEF was setting the value as expected. Does this debugging issue ring a bell with anyone? Any workarounds? Is it down to using T5 annotations on methods and them being instrumented? Regards, Jim.

RE: OT: Web Services
Martin,
Thanks for all the details. I hadn't considered the client generation at this
stage, and was planning on just relying on the published wsdl for business
consumers to use whatever package they wanted to generate a client from the
public wsdl - perhaps this is not a realistic expectation. None the less
thanks for the pom excludes / targets. They should prove useful if I go down
that route. I'm leaning toward CXF at the moment as I think it won't be a huge
step from XFire

Jim.

I've been using axis2 for several years to generate clients for a few 3rd
party web services (I presume you're talking about client code)
Can't really say I would *recommend* it because it was a pain to get it
working with Maven and I haven't even bothered to go through that again
with 1.4.x or 1.5.x so I'm still using 1.3.
But, it's very simple once you set up the build - Maven will generate
POJOs in target/generated-sources/... and when you invoke methods on those
POJOs everything just works.
The axis2 1.3 POMs are a mess though so there are lots of excludes here to
get rid of unnecessary dependencies:

Both support maven and are very complete in terms of how much of the web service set of standards they support. Metro implements JAXWS 2.1 and JAXB2.2, so if the marketing babble is to be trusted its 'meant' to be higher performing and more extensible, but I haven't tested that claim yet. In any event it has an impressive array of security features. It also ships with the standard glassfish installation, which means no server configuration is needed if you go that route, I installed it though with Tomcat, it was as easy as executing a script... not too hard at all. Depending how you wish to approach you applications, you can use annotations for the meta programming, and avoid a lot of the messy xml. I found it to be really clean and the closest to Microsofts .Net platform implementation which is IMHO a very good implementation of Web Services ...at least more impressive than anything I have seen in the Java community, but I feel the gap is closing slowly.

Good point Peter. I'll see if I can fit this in, though my work will be more migration from XFire to CXF, and using another filter to intercept ws calls, rather than the Tapestry filter, so not sure if it really counts as integrating with Tap.

Both support maven and are very complete in terms of how much of the web service set of standards they support. Metro implements JAXWS 2.1 and JAXB2.2, so if the marketing babble is to be trusted its 'meant' to be higher performing and more extensible, but I haven't tested that claim yet. In any event it has an impressive array of security features. It also ships with the standard glassfish installation, which means no server configuration is needed if you go that route, I installed it though with Tomcat, it was as easy as executing a script... not too hard at all. Depending how you wish to approach you applications, you can use annotations for the meta programming, and avoid a lot of the messy xml. I found it to be really clean and the closest to Microsofts .Net platform implementation which is IMHO a very good implementation of Web Services ...at least more impressive than anything I have seen in the Java community, but I feel the gap is closing slowly. To integrate with Tapestry I simply overrode Tapestry filter... I am not aware of any more elegant approach, although I made a few inquiries on this list in the past.

RE: [5.2.0] all our apps completly broken in IE8 (numerous javascript errors)
Andy, Not posting a fix unfortunately but we too are using the X-UA-Compatible meta tag for IE 8 - the problems we were having were related to the pager on inplace grids not working without a manual refresh, though we don't have too much custom JS so no other show stoppers so far. We also have some jQuery use in noconflict mode but I haven't tested whether that required X-UA-Compatible - once we hit the pager bug that was enough to necessitate setting compatibility mode. I will be following this thread with interest. I think a kind of interface layer to allow pluggable third party js libs is in the pipeline ...

Dmitry, From an example in an earlier post on this list, I use the approach of having: configuration.add(SymbolConstants.PRODUCTION_MODE, true); in my AppModule, so that by default production mode is always set to true for deployments, and then for any run/debug configurations in the developer's IDE, just override that setting with the VM argument: -Dtapestry.production-mode=false This means you will never need to set it for a release as the default is true.

OT: Debugging Tapestry Apps using Eclipse
I'm facing an issue with my Eclipse IDE (3.4.1) and thought I would check if anyone has faced the same issue / has a possible solution. I'm not sure when this started (last few weeks) but I'm seeing a difference in performance of over 10x between 'Run' and 'Debug' targets under Eclipse - getting to the stage that dev is unworkable. I've used a variety of JDKs from 1.5 up to 1.6u19, and have cycled the initial mem and max mem from 512m up to 2048m, with a permgen between 256 - 512m. I'm using the eclipse jetty plugin and running on a fast pc with plenty of RAM / disk space etc. When I run this app as a 'Run' target under Eclipse, or from the command line the response time is almost instant. Ring any bells with anyone? I'm trying using one of the T 5.2.0 snapshot from a few months back (5.2.0-20100603.111954-89) and also the current alpha. Startup / avg page reponse is 50s / 30s with 'Debug' targets vs. 8s / almost instant with 'Run' targets. Would be grateful for any advice. Regards, Jim.

RE: button for IE
Andreas,
The behavior I was finding was as follows:
- in FF and Chrome a href=http://asd;buttonlabelText/button/a
would render the anchor as a button (my desired outcome), and when the
button was clicked the form was NOT submitted, and the browser navigated to
http://asd
- in IE a href=http://asd;buttonlabelText/button/a would render
the anchor as a button, and when the button was clicked the form was
submitted - I think but haven't checked the value labelText was submitted.
Perhaps FF and Chrome are not behaving as the W3C spec mandates though it
would have suited my purpose. I was basing the approach on a post on the
list that I can't find at the moment.
I think other posts came up with the same conclusion I have - leave the
anchor as is and use CSS to style it.

Nine times out of ten IE is the offender and that's true in this case
as well. If the button is on a form IE submits the form which is
incorrect according to the spec. IE8 may have this right. Need to do
what Roland says and stop the event.

You're saying that if you have
a ...button .../a and you click on the button
that both the form is submitted AND the browser is navigated to the href
??

you can use the onAction(possible_context) to catch any action made by
any

I was using:

Public Link getReturnPage(){.}
. in my associated java class until I found IE doesn't behave the same
way
as Chrome / FF. I am trying to avoid having to provide an

The POI one is clearly a dependency problem and I stated as much, since it uses outdated versions of JasperReports.

Anyway, after much trial and error it turns out that Apache POI 3.2 and JasperReports 3.5.0 will get XLS working. Older JasperReport versions call deprecated POI methods, newer JasperReport versions break the Hibernate module, older POI versions have bugs that break runtime execution, and newer POI versions also break!

RE: non thread safe access to session
I do get direct access to the session from the under a very specific circumstance to allow me to commit a separate transaction unconditionally, to facilitate keeping a pre-allocated batch of keys in memory - I can't have this transaction rolled back due to a problem somewhere else, or I am left with keys that the application thinks are available, but in reality the sequence hasn't been updated in the database due to a rollback. The new session is created using session.getSessionFactory().openSession() within a single method invocation, which I'm guessing leaves me open to thread safety issues. I'm going to rearrange it to make it more service based. I think this is just down to bad coding practice.

RE: blackbird.js and IE breaking fixed CSS background image
Rich,
I'm on T5.2.0 so the code has been updated accordingly - looking through my
file history, I have:
public static MyClientInfrastructure
buildMyClientInfrastructure(@InjectService(ClientInfrastructure)
ClientInfrastructure original, @InjectService(AssetSource) AssetSource
assetSource)
{
return new MyClientInfrastructure(original,
assetSource);
}
public static void contributeAlias(
@InjectService(MyClientInfrastructure)
ClientInfrastructure cInfraService,
org.apache.tapestry5.ioc.ConfigurationAliasContribution configuration) {
configuration.add(AliasContribution.create(ClientInfrastructure.class,
cInfraService));
}
... in my AppModule. It's been a while since I looked at it so can't say
for sure but perhaps this is more in line with what is required for
T5.1.0.x. I think ClientInfrastructure is deprecated in T5.2.0. Hope this
is of use.

Yep same guy, guilty as charged. This may not be the best solution, you

get some better advice from some of the more experienced Tapestry people

indeed about just ensuring a specific order was enforced in the js
includes
for the ClientInfrastructure, but I have used a variation on it to include
my local version of blackbird.js, rather than the one that comes with
T5.1.0.5. The code is as follows:
AppModule.java:
public ClientInfrastructure
decorateClientInfrastructure(ClientInfrastructure original,
@InjectService(AssetSource) AssetSource assetSource) {
return new MyClientInfrastructure(original, assetSource);
}
MyClientInfrastructure.java:
public class MyClientInfrastructure implements ClientInfrastructure {
@Inject
AssetSource assetSource;
ClientInfrastructure clientInfrastructure;
List javascriptStack = new ArrayList();
@SuppressWarnings(unchecked)
public MyClientInfrastructure(ClientInfrastructure
clientInfrastructure, AssetSource assetSource) {
this.assetSource = assetSource;
this.clientInfrastructure = clientInfrastructure;
// Add jQuery assets in ahead of Prototype - IE8 was burping
otherwise, despite jQuery.noConflict being set
javascriptStack.add(assetSource.getAsset(null,
context:/scripts/jquery-1.4.2.min.js, null));
javascriptStack.add(assetSource.getAsset(null,

List assets = this.clientInfrastructure.getJavascriptStack();
for (Iterator i = assets.iterator(); i.hasNext();) {
Asset asset = (Asset) i.next();
if (!asset.toString().contains(blackbird.js)) {
javascriptStack.add(asset);
} else {
javascriptStack.add(assetSource.getAsset(null,
context:/scripts/blackbird_1_0/blackbird.js, null));
}
}
}
public ListAsset getJavascriptStack() {
//return clientInfrastructure.getJavascriptStack();
return javascriptStack;
}
public ListAsset getStylesheetStack() {
return clientInfrastructure.getStylesheetStack();
}
}
I have my local blackbird.js physically located in the project under
src\main\webapp\scripts\blackbird_1_0\blackbird.js.
Obviously the jQuery ordering is not relevant to your specific problem,
just
the replacement of blackbird.js is. Probably could be more
elegant/efficient, but it's just called once at startup so I wasn't too
concerned about it.
Hope this get things working for you and I don't get chewed by the more
enlightened forum members!.

I'm aware blackbird.js is not directly Tapestry code, but I'm looking
for advice on how to handle an issue with the blackbird.js file. I had

RE: blackbird.js and IE breaking fixed CSS background image
Sorry I can't be of more help Rich - we've migrated over to T5.2.0 so I
don't have a pre T5.2.0 environment I can test this under at the moment.
You're right though it shouldn't be difficult at all - I've found a lot of
these minor things have me banging my head on the desk until someone chips
in with the solution, before having the 'ahhh' moment. Hopefully someone
here can steer you straight - what exact version of Tapestry are you using?

RE: redirecting from an ajax event listener
As an alternative I think you contribute your own access control dispatcher:
AppModule.java
.
.
.
public void contributeMasterDispatcher(
OrderedConfigurationDispatcher configuration,
@InjectService(AccessControlDispatcher) Dispatcher
accessController)
{
configuration.add(AccessControlDispatcher,
accessController,
before:ComponentEvent);
}
... and just have:

.
if (request.isXHR()) {
boolean noSession = (request.getSession(false)) ==

if (noSession){
OutputStream os =
response.getOutputStream(application/json;charset=UTF-8);
os.write({\script\:\window.location.reload();\}.getBytes());
os.flush();
return true;
}
... in its dispatch method, so the timeout scenario is checked when AJAX
methods trigger a request, and redirect to your standard timeout page? This
was a solution suggested previously on this list.

non thread safe access to session
I have a service (service A) that creates some sample data, consisting of a reasonably detailed object graph where all the relations are cascaded. This service makes use of another service (service B) which manages the save of the parent entity. Service B has the hibernate session injected at bind time. I have service A called in a finite loop in the setup (@SetupRender) method of a scratch page I use for some dev testing. To cut a long story short, when playing around with the sample data creation, I found I was getting some non thread safe access to session type messages when I launched a second user session and hit the same scratch page. This doesn't happen if I mark the relevant method in service A as synchronized, but this brings with it a significant performance penalty. I'm a little concerned I may have a situation where in a high traffic scenario multiple users hitting the same service methods may get the same error. Can anyone reiterate the best practise approach for marking member fields / injected parameters as final or point me to a relevant posting on it around here - I'm sure something about marking things as final was brought up on the list not so long ago but for the life of me I can't find it. I'm not sure if it's relevant but I'm using T5.2.0-SNAPSHOT. Perhaps this isn't Tapestry relevant at all and is down to my use of Hibernate. Thanks. Regards, Jim.

RE: blackbird.js and IE breaking fixed CSS background image
Hi Rich,
Yep same guy, guilty as charged. This may not be the best solution, you may
get some better advice from some of the more experienced Tapestry people on
the forum, but it's the approach I used. The post I included earlier was
indeed about just ensuring a specific order was enforced in the js includes
for the ClientInfrastructure, but I have used a variation on it to include
my local version of blackbird.js, rather than the one that comes with
T5.1.0.5. The code is as follows:
AppModule.java:
public ClientInfrastructure
decorateClientInfrastructure(ClientInfrastructure original,
@InjectService(AssetSource) AssetSource assetSource) {
return new MyClientInfrastructure(original, assetSource);
}
MyClientInfrastructure.java:
public class MyClientInfrastructure implements ClientInfrastructure {
@Inject
AssetSource assetSource;
ClientInfrastructure clientInfrastructure;
List javascriptStack = new ArrayList();
@SuppressWarnings(unchecked)
public MyClientInfrastructure(ClientInfrastructure
clientInfrastructure, AssetSource assetSource) {
this.assetSource = assetSource;
this.clientInfrastructure = clientInfrastructure;
// Add jQuery assets in ahead of Prototype - IE8 was burping
otherwise, despite jQuery.noConflict being set
javascriptStack.add(assetSource.getAsset(null,
context:/scripts/jquery-1.4.2.min.js, null));
javascriptStack.add(assetSource.getAsset(null,
context:/scripts/jquery-ui-1.8.1.custom.min.js, null));
List assets = this.clientInfrastructure.getJavascriptStack();
for (Iterator i = assets.iterator(); i.hasNext();) {
Asset asset = (Asset) i.next();
if (!asset.toString().contains(blackbird.js)) {
javascriptStack.add(asset);
} else {
javascriptStack.add(assetSource.getAsset(null,
context:/scripts/blackbird_1_0/blackbird.js, null));
}
}
}
public ListAsset getJavascriptStack() {
//return clientInfrastructure.getJavascriptStack();
return javascriptStack;
}
public ListAsset getStylesheetStack() {
return clientInfrastructure.getStylesheetStack();
}
}
I have my local blackbird.js physically located in the project under
src\main\webapp\scripts\blackbird_1_0\blackbird.js.
Obviously the jQuery ordering is not relevant to your specific problem, just
the replacement of blackbird.js is. Probably could be more
elegant/efficient, but it's just called once at startup so I wasn't too
concerned about it.
Hope this get things working for you and I don't get chewed by the more
enlightened forum members!.
Regards,
Jim.

Ah, thanks that seems like a start, but I'm having some issues with it.
The call to the constructor in the decorator method throws a
NullPointerException, it seems because there is an issue with the
ClientInfrastructure passed into the decorator method. Also, the logic
in your example seems to be based around having one javascript library
file supersede another in the stack order. How will this apply to
getting my CSS to work? Should I pass in a second, fixed version of the
blackbird.js to the javascriptStack after the original is contributed?
Also, how exactly is an asset referenced when adding to the
javascriptStack list, as a path like generic
assets/package/name/asset.filetype ?
I'm guessing you were the guy who mentioned the blackbird issue in the
first place since your name is also Jim. Thanks for the help so far.

RE: t:grid, inPlace and rowIndex
Thanks Ville, that's very helpful. I think I'll just stick with my known object ref as the key and do a match on the list through iteration - saves some messing about. Ideally what I wanted from the grid is an index / ref that survives sorting (though has predictable behavior for additions / deletions) so it can be used for a get(index) on the source list - something like an originalIndex as opposed to a currentDisplayContextIndex - I'm would guess augmenting the model with that would be trivial but I'm aware these are general purpose components and can't really be expected to fit every specific requirement. In my case the object refs are a compound key, and when passed through an activation context require coercion, and then a check using key.equals(otherKey) per list entry until matched, which is just a few extra cpu cycles I could ideally get rid of. As you say the cost shouldn't be too much. The map backed grid seems too much square peg round hole for me. Thanks for the suggestions all the same.

Subject: [Tapestry Central] Everyone out of the Pool! Tapestry goes
singleton!
Tapestry applications are inherently stateful: during and between
requests, information in Tapestry components, value stored in fields,
stick around. This is a great thing: it lets you program a web
application in a sensible way, using stateful objects full of mutable
properties and methods to operate on those properties.
It also has its downside: Tapestry has to maintain a pool of page
instances. And in Tapestry, page instances are big: a tree of hundreds
or perhaps thousands of interrelated objects: the tree of Tapestry
structural objects that forms the basic page structure, the component
and mixin objects hanging off that tree, the binding objects that
connect parameters of components to properties of their containing
component, the template objects that represents elements and content
from component templates, and many, many more that most Tapestry
developers are kept unawares of.
This has proven to be a problem with biggest and busiest sites
constructed using Tapestry. Keeping a pool of those objects, checking
them in and out, and discarded them when no longer needed is draining
needed resources, especially heap space.
So that seems like an irreconcilable problem eh? Removing mutable state
from pages and components would turn Tapestry into something else
entirely. On the other hand, allowing mutable state means that
applications, especially big complex applications with many pages,
become memory hogs.
I suppose one approach would be to simply create a page instance for
the duration of a request, and discard it at the end. However, page
construction in Tapestry is very complicated and although some effort
was expended in Tapestry 5.1 to reduce the cost of page construction,
it is still present. Additionally, Tapestry is full of small
optimizations that improve performance ... assuming a page is reused
over time. Throwing away pages is a non-starter.
So we're back to square one ... we can't eliminate mutable state, but
(for large applications) we can't live with it either.
Tapestry has already been down this route: the way persistent fields
are handled gives the illusion that the page is kept around between
requests. You might think that Tapestry serializes the page and stores
the whole thing in the session. In reality, Tapestry is shuffling just
the individual persistent field values in to and out of the HttpSessio.
To both the end user and the Tapestry developer, it feels like the
entire page is live between requests, but it's a bit of a shell game,
providing an equivalent page instance that has the same values in its
fields.
What's going on in trunk right now is extrapolating that concept from
persistent fields to all mutable fields. Every access to every mutable
field in a Tapestry page is converted, as part of the class
transformation process, into an access against a per-thread Map of keys
and values. The end result is that a single page instance can be used
across threads without any synchronization issues and without any
conflicts. Each thread has its own per-thread Map.
This idea was suggested in years past, but the APIs to accomplish it
(as well as the necessary meta-programming savvy) just wasn't
available. However, as a side effect of rewriting and simplifying the
class transformation APIs in 5.2, it became very reasonable to do this.
Let's take an important example: handling typical, mutable fields. This
is the responsibility of the UnclaimedFieldWorker class, part of
Tapestry component class transformation pipeline. UnclaimedFieldWorker
finds fields that have not be claimed by some other part of the
pipeline and converts them to read and write their values to the
per-thread Map. A claimed field may store an injected service, asset or
component, or be a component parameter.
public class UnclaimedFieldWorker implements
ComponentClassTransformWorker { private final PerthreadManager
perThreadManager; private final ComponentClassCache classCache; static
class UnclaimedFieldConduit implements FieldValueConduit { private
final InternalComponentResources resources; private final
PerThreadValueObject fieldValue; // Set prior to the
containingPageDidLoad lifecycle event private Object fieldDefaultValue;
private UnclaimedFieldConduit(InternalComponentResources resources,
PerThreadValueObject fieldValue, Object fieldDefaultValue) {
this.resources = resources; this.fieldValue = fieldValue;
this.fieldDefaultValue = fieldDefaultValue; } public Object get() {
return fieldValue.exists() ? fieldValue.get() : fieldDefaultValue; }
public void set(Object newValue) { fieldValue.set(newValue); // This
catches the case where the instance initializer method sets a value for
the
t:grid, inPlace and rowIndex
Is there an in-built solution for a row index in the t:grid that survives sorting and works with inPlace=true - I'm currently getting the error Component X/Y/Zs is not rendering, so render variable 'rowIndex' may not be updated upon sorting. I'm trying to get something that tells me the current index of the item in a list the grid is displaying, and need the index to *not* be updated during sorting. Is this only possible with a representation on the entity the grid is displaying? Thanks, Jim.
RE: t:grid, inPlace and rowIndex
I'm using the grid to display a selection where one of the cells is an
ActionLink that currently passes the entity key for use in a detail screen
for via the context, but I want to be able to pass the entry's list index
instead of the key, to avoid a second iteration through the list (doing a
match on the key equality), ex. To be able to do list.get(n) rather than for
(Iterator iter = list.iterator(); iter.hasnext();){if x.key.equals(y.key)
then ...
I previously had an index on the persisted object the list contains, but
this is messy for inserts / deletes ...
I can work around it but if there was something built-in it would be handy.
Regards,
Jim.

What is it you're trying to accomplish, specifically? Ie, why do you need
the row index when you're not rendering?

RE: Conditional class for body
Thiago, Pablo, Thanks for the replies. I'll try one of those methods.

Conditional class for body
I've run in to a situation where the CSS class used for the body of my layout.tml varies depending on certain conditions. I've tried using variously: body t:class=t:if test=xyzTest negate=true'xyzClass'/t:if Or: t:if test= xyzTest body class='xyzClass' p:else body / p:else /t:if . and several other permutations without success - I am getting variations on parse errors with the general theme that class parameters cannot contain quotes, or that body tag must be accompanied by closing body tag etc. Can anyone suggest a working approach to this simple use case? It's important to be able to have the CSS class explicitly in the tml, and not buried in a java property. Thanks, Jim.

Hi Jim,
I've used class=${xyzClass} before in the past. Then implemented
getXyzClass() in my .java. You said it was important to not be in the
Java for you and had to be in the TML? Why is it that important when
both would require a WAR redeploy in a real production environment?

RE: chenillekit on T5.2.0
Thanks Sven. Is there any snapshot release planned soon? Or will this coincide with a T5.2.0 snapshot?
