Re: JumpStart 3.2 - for Tapestry 5.0.9
It's running ! Thanks a lot Geoff I always learn a lot from your Jumpstart Geoff Callender a écrit : Hi all, JumpStart 3.2 is now available for Tapestry 5.0.9. New features since 3.0 include: * Basic Ajax example * Joda Time example * Custom exception page example * Examples and discussion of render requests vs action requests * Best practice use of "persisting through the redirection" * Flatter structure, especially webapp (which is now more like T5's maven archetype) * More complete build files * Ant target to create a fresh project * Fixed some Firefox and IE7 formatting issues. You'll find it in the usual place: http://files.doublenegative.com.au/jumpstart Comments and suggestions are always welcome.

Very very nice.
There's a problem with absolute path for jboss.dir properties, you
should use directly ${jboss.dir} under you build.xml and not prefix
that with ${project.dir}.

Re: Editing a collection

Ok thanks I've to work on that.
If you want, I built a "ListEditor" to handle this kind of things.
It's part of my project, http://interldap.org
What you may looking for is here :
http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/trunk/src/main/java/org/interldap/wui/t5lib/components/ListEditor.java?view=markup&rev=672

That build a list of input fields, with a [delete] button next to
them, and [add new value] button at the end of the list.
Each button emits an events so that enclosing component can add or
delete matching value from list.
When you click on a button, updated values are set in the list at the
right place.
It may be use to construct simpler list editor.
Hope it may help !

I'm going through something similar right now. Looking at the docs:
http://tapestry.apache.org/tapestry5/tapestry-core/component-parameters.html#orgapachetapestrycorelibcomponentstextfield
it seems that your:
value="user.loginUser"
determines the field that gets updated when the form is submitted. So as
you've got 6x fields that point to the same field in your form, that's what
gets updated (take a peek at 'user' to confirm this).
I think you need to override the 'value' setting to point to your different
objects.

Editing a collection
Hi,
I make some nice night experience about editing a list in a form.
Here is my template
===
and here is my page
===
public class ListBean {
private List users = new ArrayList(0);
private User user;
@PageLoaded
public void initUsers(){
users.add(new User("mic1","pass1"));
users.add(new User("mic2","pass2"));
users.add(new User("mic3","pass3"));
users.add(new User("mic4","pass4"));
users.add(new User("mic5","pass5"));
users.add(new User("mic6","pass6"));
}
public void onValidate(){
System.out.println(users);
}
public List getUsers() {
return users;
}
public void setUsers(List users) {
this.users = users;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
I bump into really strange things ...
1) onValidate is called six time !! Probably as much as users.size() I
guess, is that expected ?
2) Debugging and logging show me that the list of users is never updated
whatever the input in the textfields
Is all that normal or did I miss a key concept

you can simplify the getLeftContent() method
if you use the value attribute of the Parameter

return left;

if no left parameter is passed to the layout

Re: [T5] Choosing components at runtime
John Owen Atala a écrit :
Thanks, that should be usefull, but doesn't help on the issue that to get an
instance of a component it must be injected somewhere, and that somewhere's
template must have every component that eventually you will use (because I
can't inject a component in a class whose template doesn't have it), so it
will always load every posible component...
And this is one main problem: i wanna use an injected component that it's
not on any template on a explicit way. Is there any way to get an instance
of a component that is not present on any template?
By the way, there says:
"The component may have been injected via the Component annotation, or may
have been passed to the as a parameter".
I don't know how to pass a Component as a parameter in a phase render
method, I tried:
Object beginRender(MyComponent myComponent) { ... }
I don't unsderstand the sentence this way, I woud think something like
that :
well, I may be completly wrong ... I'm gonna try it and comeback to you
to see if I find something interesting.
but myComponent variable is always null there...
What do you think?

In any case, returning a component will queue that component to be

The component to render may even be from a completely different page of

Recursive rendering of components is not allowed.
This technique allows the rendering of Tapestry pages to be /highly/

Returning a component instance does *not* short circuit method

multiple methods may return components (this is not advised -- insanity

Re: T5: Encoder and Loop
Howard Lewis Ship a écrit : That's the intent of the PrimaryKeyEncoder: to provide client/server synchronization so that TextFields inside Loops inside a Form can connect, when the client-side form is submitted, to equivalent server-side objects. ok The TextField components (and other form control element components) understand how to operate inside a loop correctly. On each pass through the loop, they render again, with a unique @name and @id attribute. There are some examples for this inside the Tapestry integration suite. I'm afraid real documentation isn't ready yet. ok, but now the intent is confirmed and I can do my search on my own. when I'll better understand it, I'll make a wiki page with an example.

T5: Encoder and Loop
Hi, Reading the doc on the loop component http://tapestry.apache.org/tapestry5/tapestry-core/component-parameters.html#orgapachetapestrycorelibcomponentsloop I can see that one of the parameter is encoder (PrymaryKeyEncoder) and this one should be used for a loop inside a form. I don't really grasp it, but does it mean that with an encoder it's possible to generate loop of textFields with validation for instance, or make me able to edit a whole collection inside a form ? If yes, someone could point examples or give hints ? Thanks a lot. -- Michael Courcy http://courcy.blogspot.com

thanks evrybody for attempting to help me with that problem. I tried every suggest you gave, with no positve result. Now I think this is a Tapetry internal problem.
Any idea for an alternative solution method?
Meanwhile I have to be happy without the regexp check.
Well you could do that inside the onValidate method of your form ...
No ?

Re: What's heartbeat ?
Hi Chris,
Chris Lewis a écrit :
I'm not an expert on this, but I can offer you a real need for
defer(). Suppose you have a mixin that attaches some trivial piece of
JavaScript to components that use it; for example, a key logger. As
far as the JS, what you need to do is register a few DOM event
handlers on an element - probably onkeypress or onkeyup, etc. Let's
suppose you wrote a class that creates such objects, and all you need
to instantiate them is the DOM id of the element.
In a simple case all you'd need to do is have your mixin include the
javascript and provide a line (like support.addScript()) to
instantiate the object in JS code - providing the component id, which
I think you can get through something like ComponentResources. Now, if
in your template code you have one component for which you explicitly
provide the DOM id, then your mixin will end up with this id. However
there are situations where you simply can't know the id before hand,
and in such cases you must rely on Tapestry to provide it.
A classic example is looping. If you have a loop that for some reason
creates a variable number of components, to which you'd like to attach
instances of your JS key logger, then you need to get the ids (created
on the fly) from Tapestry. What's more, you can't assk a component for
its id until it has already been assigned one, and the only way to be
sure that your code executes after the assignment happen is to use
Heartbeat#defer.
Now as far as when a heartbeat is created, and when/who must call
start() and end(), I'm not entirely sure. I think that a component
whose behavior interacts with/depends on that of other
components/mixins must use heartbeats to coordinate.
I understand this concept my question is how can they cooperate, It
would be really nice to have a live example involving the use of
heartbeat to get Ids of "only known at runtime component".
The only example I could find about heartbeat is to defer the firing of
an event :
Taken from http://wiki.apache.org/tapestry/Tapestry5SubmitContextComponent
Runnable sendNotification = new Runnable()
{
public void run()
{
_resources.triggerEvent(SELECTED_EVENT, new Object[] {context},
null);
}
};
// When not deferred, don't wait, fire the event now (actually, at the
end of the current
// heartbeat). This is most likely because the Submit is inside a Loop
and some contextual
// information will change if we defer. Another option might be to wait
until the next
// heartbeak?
if (_defer)
_formSupport.defer(sendNotification);
else
_heartbeat.defer(sendNotification);
But If you read the rest of this exemple, _heartbeat.begin,
_heartbeat.end are never called ... Who call them ? What means calling
them ?
I hope this helps. I'd suggest looking into the source for heartbeat's
implementation as well as what really happens inside form support's
defer method. You're not alone in your questions and expanded docs on
this would be helpful.
You're right I think a little dive in the source code would be
refreshing :-)
sincerely,
chris

Re: What's heartbeat ?
Yes thanks, I've done this first of course. It's a start but it does not bring so much light in my point of view. For instance : it does not say what's the difference between calling formSupport.defer or heartbeat.defer, do you see the difference and the conscequences on request treatment or event treatment ? If you look at this exemple : TreeGridComponent http://tapestry5-treegrid.googlecode.com/svn/trunk/tapestry5-treegrid/src/main/java/org/codelutin/tapestry/components/TreeGrid.java a hearbeat.begin is called in beginRender and heartbeat.end is called in afterRender but you can never read a call to defer, so can you explain why the author of this component call begin and end ? I really can't explain myself. What's going on if many components on a page use heartbeat, each component have its own heartbeat system, or is there a general heartbeat rythm, and each component register to it through the call to begin, end and defer ? Can two different heartbeat join and in which circumstances? Especially if a componnent contains another component ? Mybe heartbeat is something very simple and the word "heartbeat" make me think it's bigger but I don't find that so clear when I start to read it in real components.

I have a listEditor that build a list of property editor with the possibility to add/remove/update properties. I built it to handle simple properties (String, Enum, date...), but it seems to work as long as you have an editor associated with the property type : I use it to handle a list of criterion, which are a complex object (well, complex...). In your case, you would have to define a personEditor (surely just a beanEditor). It should (at least :) need a lot more of polish, but it work rather nicely. For example, if you want to edit a list of string, say "bleue", "red" and that the editor for String is "text", the rendered template is : [blue] [red] The "[]" are text input fields, "<>" are buttons. The component generate event on button selection so that the parent element can handle matching action (add or remove element, with perhaps other business logic).

Re: [T5] 5.0.7 ajax update
Hi
i used this example for tapestry 5.0.6 to update some components:
Where did you read this example ? On the wiki ?
Thanks.

hi,
i used this example for tapestry 5.0.6 to update some components:
public Object onMyAction()

MarkupWriter markupWriter =

markupWriter.element("component");
_pageRenderInitializer.setup(markupWriter);
Page page =

ComponentPageElement element =

markupWriter.end();
_pageRenderInitializer.cleanup(markupWriter);
return new TextStreamResponse("text/html",
markupWriter.toString());
}
but for 5.0.7 this code doesnt work.
How partial page rendering should be done using 5.0.7??
thanks for any help

Re: Get application context from within a BasePage subclass
If you are working on Tapestry 5 you can read this wiki : http://wiki.apache.org/tapestry/Tapstry5First_project_with_Tapestry5,_Spring_and_Hibernate Kaspar Fischer a écrit : Hi, The Tapestry reference, http://static.springframework.org/spring/docs/2.0.x/reference/webintegration.html#webintegration-common says that "[...] one can use the following code snippet to get access to this 'business context' ApplicationContext created by the ContextLoaderListener": WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext); How would I do this from within a page (i.e., a subclass of BasePage)? IIUC, a page need not have an associated servletContext. So what sort of indirection would I use? I am trying to get the Spring WebApplicationContext service that (apparently) the tapestry-spring.jar, http://tapestry.apache.org/tapestry5/tapestry-spring/ adds.

Re: How to initialize a session variable in a page render request?
I may be wrong as I'm a tapestry newbie, but pageAttached is something
related to the compilation and pooling of the page template. Thus it
should not deal with session buisness.
jeffrey ai a écrit :
Hi Folks,
I am looking for the best way to initialize a session variable(@Persist) in
a page render request once, so I could access it in the next action request.
I tried to put the logic into "pageAttached" method like below:
@Persist
private xxx myVar;
@SuppressWarnings(value = "unused")
private void pageAttached()
{
if (myVar == null) initializeVar();
}
It doesn't work as I expected. myVar is always null in "pageAttached"
method. It seems the "pageAttached" method is not supposed to mutate a
persistent variable.
However, if I put this logic into some other place like below, it works
fine.
@Persist
private xxx myVar;
public String getSomeOtherVar()
{
if (myVar == null) initializeVar();
return someOtherVar;
}
Although it works, apparently, this is not a good place.
Is there a better place to do session variable initialization?
I believe it should not be put into constructor too because it will be
viewable to other sessions.
Thanks,
Jeffrey Ai

How to make a basic crud; feedback wanted
Hi, This is the second edition of "how to make a basic crud with tapestry5" ;-) http://wiki.apache.org/tapestry/Tapestry5How_to_make_a_basic_crud I did it because as a newbie I really needed one. If you think there could be much better way to do it, or tapestry is not used as it should be, please let me know. -- Michael Courcy http://courcy.blogspot.com
Re: How to make a basic crud : Feedback wanted
Vjeran Marcinko a écrit : Hi. Although your example is very simple in code as such, it suffers from some drawbacks, mainly because you don't have activation context for Save page. 1. Your create and edit actions on Start page use ActionLinks which make 2 HTTP requests (action + render Save page), whereas PageLinks with "myBeanId" context value would execute just one HTTP request which will just render Save page, and that is all you actually need Did you mean that instead of You'd rather see 2. Its always good practice to pass only necessary activation context values (in this case myBeanId), and let page itself be responsible to reconstructing all that is necessary, meaning, it is not good to instantiate new MyBean or fetch it from database outside of Save page as in your case, but to do it inside it, in onPrepare event method. This way if you have some additions to save page which maybe lead to another page and get back to it, all you need to do when getting back to Save page is to make certain this entity ID is present there, and page will know how to reconstruct itself. You are right 3. If you keep only "myBeanId" inside Save as Session persistent value, your Session has much less overhead in cluster recplication then when holding whole instances. Though I guess this is just small gain, often dismissable. ok Of course, all the written above depends on situation and your needs.

Re: T5 Newbie : populate the value of a form in a bean
In my case I think I was running in confusion, the MyObject was already
initialized from a previous page and injected in the page that hold the
form.
Thus initialising it from onPrepareFromForm or setupRender is useless in
this particular case.
Things are working fine now, I really don't see what was wrong before as
I can't see what's better now ...
Newbie bad time. Josh send me good vibes ;-)
I'm going to produce a little wiki tutorial on Basic Crud this weekend
because that really miss me.
Thanks for your help and your explainations.
Howard Lewis Ship a écrit :
Generally, what you want to do is replace setupRender() with
onPrepareFromForm().
void onPrepareFromForm()
{
if (_myObject == null) _myObject = new MyObject();
}
"Prepare" means the prepare event, fired from your Form component.
Prepare event is triggered when the form starts to render AND when it
starts to process a submission. Instantiating and object is exactly
what prepare is intended for.
Tapestry will supply an id of "form" for the component. If
you have multiple forms, they may end up being "form", "form_0",
"form_1". I tend to give an explicit id.
You test page is a little different, in that it displays the contents
of the myObject property as well, so your setupRender() should do the
job (because the _myObject field is persistent).

Re: T5 Newbie : populate the value of a form in a bean
The t:id attribute is not meant as a way to tell Tapestry what are you
editing: it's just an id that you can use to refer to it in another
component (Label, for example) or in your page class.
Ok you're right but if I try this
I get a failure because tapestry expect an id
Then if I do this
I have to provide the setter and the getter for name and I still get an
error when I submit.
The only thing that work properly is this
But I comeback to my initial question : I just can't populate the value
to the bean directly from the form
The best thing I can do is this
public String getName(){
return user.getName();
}
public void setName(String name){
user.setName(name);
}

When I see the Snapshot for the typicall project, there is something
else as

Re: Feedback wanted on IoC documentation
Ok I think I have understood your explainations (actually I'm not pretty
sure)
The component is totally managed by tapestry and by injecting services
through @Inject annotation you get more control on its fields.
While in the other hand you encourage proper storage of service by
making injection only available through constructor.
Well, honestly I don't have enough experiences to assess that, it's
doing the job properly anyway, I was a bit curious that's all.
I agree on the fact that making those two ways dependencies injection
available in both context won't bring that much compare to the
expectation of the community : Ajax and the next tutorial on form ;-).
Thanks for your answer.
Michael
Howard Lewis Ship a écrit :
Services are loaded by the normal class loader without any special
trickery. We create classes (proxies and such), but don't modify
existing classes for Tapestry IoC. This is necessary to ensure that
services code inter-operates properly with all kinds of third party,
legacy and other code that is far, far beyond the scope of Tapestry
IoC.
To encourage service implementations to properly store service
depenencies as final instance variables, such dependencies are passed
only into the constructor.
So for services, injection is assumed, for the constructor parameters
(as if an @Inject annotation was present).
Now for components, it's a different story. The component classes are
very specific to Tapestry, not intended for reuse elsewhere, and are
modified at runtime to work properly and efficiently within the
constraints of Tapestry's multi-threaded runtime environment.
Tapestry components are quite a bit different from service, in terms
of lifecycle, and in terms of the what can be injected (all sorts of
resources besides services) and in the fact that they quite often have
considerable (if largely temporary)
internal state, while services most often have no internal state at all.
Constructor injection is insufficient for components, because Tapestry
needs to really know about the individual fields. For example, if
you:
@Inject
private MyService _service;
... and then in some code:
void onActionFromNotAGoodIdea()
{
_service = new MyOtherImpl();
}
You'll actually get a runtime error explaining that the field is read only.
So field injection is both necessary and requires far less typing ...
you don't have to write a constructor and assigning all the fields
from it. On the other hand, the fields aren't final (though they often
act final).
The real downside is that you have a similar concept, injection, with
two very different expressions.
It would be interesting if Tapestry IoC could support injection on
fields, and "backtrack" from the field to the constructor parameter.
It might also be interesting if components could define a constructor
and Tapestry could work forwards from the parameter annotations
forwards to the fields. I think both approaches would require a large
amount of effort and may not actually add any value.
Certainly in the short term, people would be much happier if we got
the Ajax support going.
Of course, I'm writing this on my PC while I get Leopard installed
onto my Mac (my main development machine).

How to contribute a new Request Handler
Hi
I'm really new to tapestry, and I was trying to contribute a new
request Handler
So I follow the documentation and the example provided by the archetype
first I provide a builder for my RequestHandlerService :
public RequestFilter buildMichaelFilter(final Logger log){
return new RequestFilter(){
public boolean service(Request request, Response response,
RequestHandler requestHandler) throws IOException {
try{
log.info("Mic before");
return requestHandler.service(request, response);
}finally{
log.info("Mic after");
}
}
};
}
And then I contribute it :
public void contributeRequestHandler(OrderedConfiguration
configuration,
@InjectService("MichaelFilter")
RequestFilter michaelFilter,
@InjectService("TimingFilter")
RequestFilter timingFilter
)
{
// 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("Michael", michaelFilter);
configuration.add("Timing", timingFilter);
}
And nothing is logged from the michaelFilter ... while the timingFilter
keep on working like before.
I probably misunderstood something.
Any idea ?

Re: T5: Property binding

Hi,
Tapestry seems to only accept properties with getXxx() and setXxx()
accessor methods, or isXxx() for boolean values. This is ok when using
your own bean classes, but I just tried to output the number of entries
in a java.util.List using
${list.size}
in my .tml file (with a "public List getList()" method in the
corresponding java class), and I get an exception page with the
following error message:
Class java.util.List does not contain a property named 'size' (within
property expression 'list.size'). Available properties: empty.
This is because java.util.List does not provide a getSize() method, only
a size() method.
Is it a design decision to only go for getXxx() accessor methods, or
would you think about trying xxx() if getXxx() can not be found?

typo in the documentation
Hi
I think there's a small typo in the documentation in
http://tapestry.apache.org/tapestry5/tapestry-ioc/service.html
In the section : Injecting dependencies
==
For example, let's say the Indexer needs a JobScheduler to control when
it executes, and a FileSystem to access files and store indexes.
public static Indexer build(JobScheduler scheduler, FileSystem fileSystem)
{
IndexerImpl indexer = new IndexerImpl(fileSystem);
scheduler.scheduleDailyJob(indexer);
return indexer;
}
Here we've annotated the parameters of the service builder method to
identify what service to inject for that parameter.
But there's no anotation at all so I think the author meant
