Patching Tapestry for IE9 Prototype Bug
Hi Folks, We're on T 5.2.4.

Re: Patching Tapestry for IE9 Prototype Bug
rant It's pretty frustrating there there is no procedure on the Tap website for patching 5.2.X for the prototype IE9 bug. And any links in the mailing list archive that point to git have expired. I'd have thought this was a pretty serious bug. Unfortunately for us we've only just realised it's affecting our users (our bad for not testing IE9 properly). In frustration I'm now downloading the 5.3 alpha - with all the headaches a version upgrade entails (breaking changes / testing etc...) But it seems there are only source files available for 5.3, which is fine but ant now seems to insist on various maven artefacts, or it barfs. Why does everything need to go through maven/gradle/yet-another-random-build-system ? What's wrong with a simple ant build? /rant Anyway, are there a) any binaries for 5.3 or a simple ant build target ? b) a comprehensive patch with instructions for the IE9 zone/prototype bug ?

Ajax callback for checkbox component?
Hi Folks,
You can register for an ajax callback from select components like so:
page.tml:
t:select t:id=name value=name model=nameModel blankOption=NEVER
t:zone=buttonZone /
Page.java:
Object onValueChangedFromName(String name) {
// update zone
}
Is there an equivalent callback for a checkbox?
Thanks!

Access component via http request
Hi,
Is it possible to invoke a component directly via HTTP?
E.g given a Tapestry Page:
public class MyPage {
Object onMyRequest() {
return something;
}
}
I can call http://myapp/mypage:myrequest/ to return something.
Can I do the same for a component?
Cheers,
Joel

Can I access a component out of the context of a page?
i.e. does a component have to be bound to a Page to be rendered?
I'm trying render a simple html template and fetch it from my JS.

It's not recommended to access components directly, but you can @Inject
ComponentResources and use its createEventLink() method.

Re: Access component via http request
hmm, how about using the tapx TemplateAPI and TemplateRenderer within a
tapestry app?
I don't need to do anything fancy like Page rendering, and infact am
just using a Page instance as useful hook for ajax methods.
From this method I just want to return some html rendered with tml,
using tap's templating expression language.
I've used tapx TemplateRenderer before with success, for sending HTML
emails. Was hoping to do something similar now, although having tried it
I get the following error:
TemplateAPI templateAPI = new TemplateAPI(mypackage.web, new
File(/web/components));
TemplateRenderer renderer = templateAPI.createRenderer(Tiles, en,
default);
RenderedStream renderedStream = renderer.render();
throws:
Caused by: java.lang.IllegalArgumentException: Location 'default' is not
defined. Defined location names: (none).
Any clues as to how to fix that error?

You can ask any component to generate an event request Link using its
component resources. In Tapestry, you don't try to second guess, on
the client side, what links will look like ... you ask the server side
to generate a link, and then your JavaScript code can send Ajax
requests to that component.
In terms of what you are trying to do ... Tapestry assumes most
requests from the client will generate a partial page render response
... a particular format JSON response that contains HTML plus details
about JavaScript libraries and initializations. In any case, that's
what a Zone (or anything Zone-like) needs. If you can, use Zone.
Alternately, a component may send a response directly back to the
client, which it be text, HTML, JSON, or something binary.

Re: Access component via http request
Good question, my rational was that I *might want need to re-use the
template I'm creating inside a Tap Page soon, so I thought I would start
off by making the html I need to render a Component (as I could access
and render a component directly via an http request).
I could always embed the Component within an empty wrapper Page and
access that via http, but I was hoping this wouldn't be necessary.

Re: Method arguments in template expansions

I had tried it, but forgotten that method names are not shortened, so as
Robert suggested you have to use the full method name:
${getFoo('bar')}
works.
${foo('bar')}
does not.

Re: Live class reloading very slow
Hi Davor, Have you tried running Jetty standalone, out of eclipse? This is what we do. I'm not sure it has anything to do with your problem but it might be worth a try. It's only a few lines of code to write a simple Jetty server launcher as you can see http://pastebin.com/WsEFi2yh Just write a simple script to run for this class and even though you'll be using Jetty outside of eclipse you can still make code changes in eclipse and it will reload them dynamically (as long as you set your classpath for the jetty startup script correctly). - J On Wed, 2011-05-25 at 10:17 +0200, Davor Hrg wrote: Hi, your suggestion did improve reload when only template is changed.

Re: The right way to manually update a zone in tapestry
OK figured it out...
Trick is to use the ZoneManager for the zone id (see Tapestry.js) :
So this ajax request, to update a zone, works, and all the tap js
callbacks on components are registered correctly
var zoneManager = Tapestry.findZoneManagerForZone('my-zone-id');
$.get(/home.alerts:blockPath, {url:ignore_url, fullurl:fullurl,
ccid:ccid, area:ignore_isarea, title:title,block:block},
function(responseJSON) {
zoneManager.processReply(responseJSON);
});

Hi,
I am calling a Tapestry action link manually from js, it's an ajax call
that returns a zone. I then swap out the old zone for the new zone html.
This all works well, except for that fact that any Tapestry js callbacks
that would normally be triggered when the zone loads on the page (i.e.
if this was all done Tap via an action link zone update) are not called,
resulting in actionlinks within the zone that do not work as expected.
Is there a correct way to swap out a zone on a page manually using js,
possibly calling one of the Tapestry.js functions?

Re: dynamically changing event link context on client side using js
Hi Thiago, Using this approach, if I was to invoke this ajax URL I'd have to process the zone response myself manually. What I'd like to be able to do is update the context or params on an event link so that when the clicks on it the response and corresponding zone update is automatically taken care of. Now, I can update the context or request params on the client side, but it seems like these updates are ignored For example: If I have an tapestry event link on the page which generates the following html: a id=ignore2 onclick=javascript:return Tapestry.waitForPage(event); href=/home.alerts:ignore2mylink/a I can update the href using js to add a request parameter: a id=ignore2 onclick=javascript:return Tapestry.waitForPage(event); href=/home.alerts:ignore2?param=valuemylink/a or add a context: a id=ignore2 onclick=javascript:return Tapestry.waitForPage(event); href=/home.alerts:ignore2/valuemylink/a but what is submitted to the server when the link is selected is always the original url: /home.alerts:ignore2 there seems to be no simple way around this?! - Joel On Mon, 2011-03-28 at 19:30 -0300, Thiago H. de Paula Figueiredo wrote: On Mon, 28 Mar 2011 19:10:00 -0300, Joel Halbert j...@su3analytics.com wrote: I need a way of submitting the dynamic content back to the server as part of an ajax request I'm not clear how I would be able to do this in the manner you suggest.

This is funny because I thought that is exactly what you are trying to do. If you are going to exclude modules from a deployment but don't want to do it from system properties, then you must be creating an app module that uses your multi-module jar? If that's the case then you can define your dependencies using the @SubModule annotation on your deployed AppModule. If all of your included modules also define their dependencies this way then you don't have to worry about extra's getting loaded, just don't use the Manifest auto-loading.

Re: No service implements the interface org.springframework.context.ApplicationContext.
OK, figured it out. I didn't realise that TapIOC loads ANY modules that
it finds (in the classpath).
Removing the tapestry-spring.jar fixed the problem.
Is there a way to explicitly prevent TapIOC loading a module, so that I
can continue to have SpringModule on the classpath, but without it being
loaded?

That can take many forms; one opportunity is right here on JavaLobby in a thread discussing the new 5.2 release: http://java.dzone.com/articles/announcing-tapestry-52 If you value Tapestry and the vast amount of time and effort the Tapestry team has provided to you, then you should take a few minutes to write a short comment in the discussion thread about why you like Tapestry. Please try to do so briefly, concretely, and without bashing other frameworks.

encoding, so thanks for the explanation.
I'll use Nicolas's solution to override this behaviour.

Re: [Tapestry Central] Why chose Tapestry?
and Julie to share knowledge so that they can understand each other's code. Even if pairing occurs only part time, it's very effective at knowledge transfer as well as ordinary coding. The idea that mediocre developers should use JSF as it is more tolerant of errors is absurd! Tapestry 5 is designed to improve productivity for all developers, by streamlining, simplifying, being smart and being concise ... not to mention live class reloading and best-of-breed exception reporting, which makes it fast to identify and fix those errors. If your doctor tells you to eat less red meat, that doesn't mean you should switch to a diet of fried chicken three meals a day! Likewise, if you have concerns with code quality from your developers, you should not switch to a less agile, more code-intensive, less supportive development model and hope to catch all the bugs in QA. Sweeping problems under the rug is never a winning strategy. Coming down off my soap box, I should also add that Tapestry 5.1 works a little bit differently than 5.0 in this respect, so it does (in fact) defer more of the page loading and validation until a link is actually clicked. This is more for performance reasons than to shield developers from application problems. Even in 5.0, the loading and validation was the reach from page A to pages explicitly referenced (usually via PageLink during the rendering of page A), so it's a highly unlikely case that a single error in a 1000 page application will keep the application from starting up, unless the start page of the application links to all 999 other pages. Re-reading the above post I can't emphasize enough: you can't ignore quality problems. Quality problems lead to development failures, schedule slips, missing functionality, low morale and high turnover. Saying we don't have time to fix the quality problem first is to ignore the the second law of Thermodynamics. You are expecting a miracle, literally writing it into your project plan. Formos addresses this issue two ways: First, we use Scrum and deliver on (typically) 4 week cycles. Thus we set real deadlines and have a constant check on quality (we're providing working code constantly). We don't even try to predict what we'll be doing six months or two years from now, we just deliver a steady, manageable stream of software. Secondly, Formos uses Tapestry because of all the reasons that the anonymous developer's organization rejected it, and for many, many more reasons besides. -- Posted By Howard to Tapestry Central at 6/16/2009 03:45:00 PM - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org -- Joel Halbert 020 3051 8637 075 2501 0825 j...@su3analytics.com www.su3analytics.com www.storequery.com SU3 Analytics Ltd, The Print House, 18 Ashwin St, London E8 3DL. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

I have a desire to use a context where the delimeter for one of the values is itself a '/'. For example: /docs/my/path/to/doc/document1/param1/param2 I can do this by hand in a page by having onActivate(EventContext ctx) and iterating the elements of the path. However, what if param2 is optional? Also, it means I have to do this work manually on every page. I realise that to make this work more generally I'd need to have another kind of separator in there, eg: /docs/my/path/to/doc/document1/-/param1/param2 I'd might then have a signature like: void onActivate(DocPath path, Object param1, Object param2) and have the T5 machinery encode/decode urls accordingly. Is this possible or am I asking too much? This is all in a drive to having nice looking URLs... A simpler alternative might be to simply use a different context value separater, eg. '-' for apps where the context values are themselves meaningful paths. Is this possible? This would lead to a url like: /docs/my/path/to/doc/document1-param1-param2 Which kind of works for me.

Re: T5: Passing named/structured-type params in URLs?
Hi Andy,
The same Encoder could indeed be used across multiple pages.
Some pointers:
You need to create one of these:
http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/ValueEncoder.html
Look at the source for one of the existing implementation for ideas,
e.g. StringEncoder
I've attached an example implementation of a MapValueEncoder.java
You will then need to configure your Tap App to use your encoder e.g.
public static void
contributeValueEncoderSource(MappedConfigurationClass,
ValueEncoderFactory configuration) {
configuration.add(Map.class, new
GenericValueEncoderFactoryMap(new
MapValueEncoder()));
}
You can then have activation context's that take a Map e.g.
protected boolean onActivate(Map params) {
id = params.get(id);
}
I'm sure there is a doc page for encoders, although I cann't seem to dig
it out.

I did actually try writing something like this a while ago. The problem
is that you need to specify more than just the name of the parameter,
you need to know which component it's part of.
I ended up with urls like:
/page?component1.component2.param=somevaluecomponent1.component3.param2=somevalue
So as you can see, they quickly become very large.
You could mandate that only top-level components (ie, pages) can use
that persistence strategy, but that seems to be counter-intuitive.
I toyed with the idea of mapping those names to some smaller IDs - a
service which simply converts p1 to component1.component2.param so
you could have urls looking like:
/page?p1=somevaluep2=somevalue
The problem then is it's hard to work out what the params actually are
for the user/developer. Also, how do you populate that map to start
with? You'd have to load each page and component class at startup.
I didn't ever finish this code as I worked out how to do what I wanted
with vanilla PageActicationContext in the end.
Robert Zeigler wrote:
That should work.
I think it could be interesting, though, if tapestry provided an
additional persistence mechanism, ala:
@Persist(PersistenceConstants.QUERY_PARAMETER)
private String p;
@Persist(PersistenceConstants.QUERY_PARAMETR)
private Integer irn;
which would then take the values in p and irn and stash them in the url,
like:
p=valueEncodedValueirn=valueEncodedValue
Obviously this wouldn't be appropriate to use everywhere; if you're
concerned about users tampering with URLs, you'd want to avoid it.
But in cases like that presented below, where you expressly want users
to be able to muck about with parameters, it would be useful.
Note that this is similar to the current client-side persistence
mechanism, except that mechanism a) rolls all persisted values into a
single parameter and b) base64 encodes the parameter.
As long as you've got the basic mechanism for doing the above, you could
translate it into a pretty url via url rewriting without too much
trouble.
Thoughts?

know where to start looking! Help, please!? ;)
Just use a List as the activation context value. For each named
parameter one want, add the name first, the value second.
The above URL would be constructed by Tapestry if you returned a List
populated like this:
List list = new ArrayList();
list.add(irn);
list.add(1245569);
list.add(d);
list.add(1,2,4);
Then, declare a onActivate(EventContext context) method and
reconstruct the pairs:
for (int i = 0; i context.getCount() / 2; i++) {
String name = context.get(String.class, i * 2);
String value = context.get(String.class, i * 2 + 1) // instead of
String, you could use any type here
}
I have not tested this code, but I guess you get the idea. ;)

Re: Solving the T5 Documentation Dilemma
The primary concern, at the moment, seems to be encouraging people to contribute documentation, tutorials and examples. Making the adding, updating and extension of docs as open (so anyone can do it) and simple (so it is not an arduous task) is the key to this. Howard's suggestion of using the confluence Wiki - and taking snapshots of docs whenever a new release is done makes sense. I would encourage anyone to contribute, and I'm sure that the regular reviewers will compensate for occasional inaccuracies. Anything more cumbersome will put people off. I don't like the idea of tying it into Maven. I for one don't use Maven, and the perceived additional complexity may put others off experimenting using Tap. -Original Message- From: Otho taa...@googlemail.com Reply-To: Tapestry users users@tapestry.apache.org To: Tapestry users users@tapestry.apache.org Subject: Re: Solving the T5 Documentation Dilemma Date: Fri, 1 May 2009 08:43:30 +0200 I would suggest splitting the documentation. There should be the reference documentation by the creators/commiters of the project, whis is organized like a book covering all the different aspects of tapestry 5 in a reference manner eg like spring or hibernate docs. These are tied to the release version, too. And then there should be the community docs with tutorials, howto's, recipes and so on on a wiki. There should be a pattern in the templates which requires or at least pushes you, to mention the version of Tapestry you are using. And lastly I would suggest setting up a forum. Information is more easily organized there and searching is more convenient than wíth a mailing list alone. I would think that the barrier of contributing to a forum is lower than that of contributing to / asking on a mailinglist. Well, the latter can also be seen as a feature in a way, but publicity and visibility never really hurt IMO. 2009/4/30 Piero Sartini p...@sartini-its.com I don't think Tapestry's wiki, http://wiki.apache.org/tapestry, is up to the task. Confluence is available with apache as well. There is already a space available at http://cwiki.apache.org/TAPESTRY/ ... maybe its just a matter of adding content to it?

damn, my last email was sent before i'd finished...

For the time being I'm going to solve the problem by hardwiring the
charset
public static void contributeAlias(
ConfigurationAliasContributionMarkupWriterFactory
configuration
) {
configuration.add(AliasContribution.create(MarkupWriterFactory.class,
new XhtmlMarkupWriterFactoryImpl(UTF-8)));
}
I should not imaging that injecting services into the alias contribution
is something that will be required much anyway

when this is commented out it no longer throws the error, I guess the
double dependency on SymbolSource is causing the problem...?

Re: [T5] Persistent fields may not be updated until after the page has finished loading
in relation to this thread - and specifically in relation to using
pageAttached() to initialise p[age fields - I raised the following
possible bug the other day,
https://issues.apache.org/jira/browse/TAP5-374
I was wondering if this was something anyone else had
noticed/reproduced?
On Fri, 2008-11-21 at 12:32 -0800, Eric Ma wrote:
Thanks for your reply. I have a follow up question:
For @Persist field, when and how does variable binding (from HTTP
session-cached value) happen?
Let me explain:
Previously, when I use inline (or constructor-based) variable
initialization, although I don't know how the magic works, I am guaranteed
that only the first time a component/page object is instantiated, the
@Persist field is populated with the initial value. Subsequently when the
component/page object is retrieved from the object pool and re-used, it is
not the initial value, but the session-cached value, that is associated with
the variable. This is important because the field value might have changed
due to user action between the object instantiation and re-use.
If I have to assign value explicitly in @SetupRender, since that method is
always called by Tapestry whether this is a new or re-used object instance,
to ensure the session-cached value is bound to the filed, do I have to do
(can we assume this is how T5 actually work behind the scene)?
@SetupRender () {
void initializeField() {
if(session.getAttribute(persistedFieldName) == null) {
myPersistedField = some initial value;
}
}
, which has 2 major problems:
1. I have to touch HttpSession, something that T5 makes every effort to hide
from me.
2. Can I assume the session key is actually the session key. What if the T5
internal implementation changes tomorrow?
Marcel Sammut wrote:
I had the same problem when moving to 5.0.16. It was pretty simple for
me, since what I was doing was initializing my persistant variables in the
declaration. What I did was move the initialization to the SetupRender
phase of the cycle.
For example:
@Persist
private int count = 0;
became:
@Persist
private int count;
@SetupRender
void setupRender() {
count = 0;
}
Hope that works for you too.
Cheers,
Marcel

T5: Page instance variable default values
Hi, With reference to: http://tapestry.apache.org/tapestry5/guide/lifecycle.html Tapestry takes special care to purge all instance variables back to their default value at the end of each request. How is the default value determined? I have noticed that if I declare a class variable on my page, like so: private HashSetString myVar = new HashSetString(); It's state will persist across requests i.e. if on one page request I populate it, the populated state will be visible to the next request, whereas I was expecting an empty Set. Is this expected, I can initialise my variable within onActivate or a @SetupRender method instead, but I want to check in to see what the documented behaviour should be.

Hi, Is it possible to use an annotation to define which method should be used to set the page activation context? i.e. I would like to define an onActivate() method, but have it called something else, e.g. onActivateX(). A reason for wanting to do so is to ensure that i may have a single onActivate method in a base class which is always called regardless of wether there are onActivate methods in subclasses (that might otherwise override it and not call super.onActivate()).

Re: T5: Using an annotation to define which is the page activation context / onActivate method ?
just realised that the order of invocation of onActivate methods is the other way around to that which i thought it was: http://markmail.org/message/7o52hrmcvli3jsje This does pose the question though: how can I invoke base functionality after subclasses have been initialised, but before PageRender? hmmm (being Saturday I've very likely missed something here) On Sat, 2008-11-08 at 14:40 +, Joel Halbert wrote: Hi, Is it possible to use an annotation to define which method should be used to set the page activation context? i.e. I would like to define an onActivate() method, but have it called something else, e.g. onActivateX().

Rationale behind all possible onActivate methods invoked when context is supplied
Hi,
I've been thinking about how onActivate methods are called...
If i have a page with two onActivate methods:
MyPage.onActivate(int modelId1, int modelId2);
MyPage.onActivate(int modelId1, int modelId2, int modelId3);
and if i have a link to this page which supplies the full 3 argument
context, (e.g. http://bla.com/MyPage/1/2/3) then T5 will invoke the
second method and then the first.
What is the rational behind thiinvoking both onActivate methods for the
same context?
If onActivate methods are an opportunity to intialise models (in this
case by looking up the model based on the supplied id) then having both
methods invoked requires us to be defensive about initialisation, if we
want to avoid unecessary model intialisation and data access:
e.g. i need to write something like this in the first of the above two
methods:
onActivate(int modelId1, int modelId2){
if (model1 != null) {
model1 = model1Dao.getById(model1Id);
}
if (model2 != null) {
model2 = model2Dao.getById(model1Id);
}
}
(I'm not presuming to have model caching, which i do, but this is incidental to
the problem illustrated)
I'd be interested to hear how others handle this, and what the merit of having
all available onActivate methods
invoked is when the full context is supplied.
Rgs,
Joel

Access to T5 Services - how to get a handle on to Registry?

How can you access a T5 Service within a class that is not managed by Tap IoC (thus the dependency can not be injected) and does not have access to the ServletContext (thus the dependency can not be looked up manually from the Registry (the registry is set as a servlet context parameter)) ?

Re: Access to T5 Services - how to get a handle on to Registry?
OK, i figured it out, I didn;t realise you can inject services into the
contribute methods:
something like...
public static void contributeBindingSource(
MappedConfigurationString, BindingFactory
configuration,
BindingSource bindingSource,
@InjectService(SymbolSource)
SymbolSource symbolSource
) {
configuration.add(list, new ListBindingFactory(bindingSource));
configuration.add(symb, new SymbolBindingFactory(symbolSource));
}
(IoC on steroids !!)

Re: T5 arguments to methods in expressions
Sounds good.
With respect to expressions, although having a lot of logic in the page
can quickly become unwieldy, the ability to use simple ternaries and
evaluate functions with arguments is certainly appealing and allow for
more concise code.

I expect to revamp the property expression language in 5.1 (or perhaps
5.2, depending on priorities) to support this, almost. Unless I get
very clever, I don't think we'll see ${var:index} allowed ... you'll
have to use a real property, not a var: psuedo-property, but then it
will look lke:
t:source=promotedCols(index)
I also expect to add some ternary operator (test ? expr1 : expr2), a
smart dereference ([ expr ] that can be applied to arrays, Lists
and Maps), and maybe some simple filtering / projection operators,
along with method invocation.
/tr
Is this allowed? I ask because the above code does not throw an exception,
however the promotedCols(int) method is NEVER invoked although the inner
loop iterates exactly ONCE (although it should be more times).
Is this behaviour is a bug?

i.e. I would like to be able to reference a page like this:

I don't think so. Other option would be the page paramameter from
PageLink to also accept Class instances. We would have
refactoring-proof PageLink usage. It would be something like this:
t:page=prop:nextPage
public Class getNextPage() {
return NextPage.class;
}
You can easily add a new name parameter binding to do what you want.
You can follow this example from the Tapestry wiki:
http://wiki.apache.org/tapestry/Tapestry5HowToAddMapBindingPrefix and
use a properties file to store the name/page mappings.
Hurray for Tapestry flexibility! :)
