[T5] URL encoding maze : post to encoded URL (even in 5.0.9) ?
Hello, I'm still stick with some encoding issue for URL using UTF-8. I'm stick with Tapestry 5.0.6. I applied the patch for TAPESTRY- bug ( https://issues.apache.org/jira/secure/attachment/12371922/context_encode_decode_fix_to_5.0.6.patch), what solves a lot of problem. But it's not over, and that part applies even to Tapestry 5.0.9 : It seems that post are posted the the encoded URL. The following post is also done to the encoded URL, but that part is decoded by the servlet API call to getServletPath(). So, if (as it's in my case) you use onActivate(String name) in a page using a post, the name given to onActivate for the post action will receive a non decoded String. If some validation are done based on that encoded value, as a check in DB, they fail. So, as I figure I'm not the only one to do this kind of things, and that I'm doing something bad. Please, would somebody show me my error ? -- Francois Armand Etudes Développements J2EE Groupe Linagora - http://www.linagora.com Tél.: +33 (0)1 58 18 68 28 --- InterLDAP - http://interldap.org FederID - http://www.federid.org/ Open Source identities management and federation - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

You mean that using value=user.loginUser tapestry alway update the
same thing.
Thus if I change the method
User {
void setLoginUser(String loginUser){
this.loginUser = loginUser;
System.out.println(loginUser);
}
It should at least output the value I input in my textField ...
And that's right, it actually what's going on the input are correctly
output
But When I outout the user itself in the page
public void setUser(User user) {
this.user = user;
System.out.println(user);
}
the old value is kept
actually setUser is call before setLoginUser ...
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=markuprev=672
And here there is an example of use case (it really lacks a lot of doc) :
http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/trunk/src/main/resources/org/interldap/wui/t5lib/components/eschema/EditAttribute.tml?view=markuprev=568
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 !

addScript(), entities, CDATA...
Hello,
I'm running (again) in problems with entities filtering.
Since https://issues.apache.org/jira/browse/TAPESTRY-1818 is corrected,
now I can add JavaScript with '' in CDATA block but only if I set the
rendering type to text/xml (with
@Meta(tapestry.response-content-type=text/xml) so that the parser
understand them.
Now, I would like to also be able to use comparators in the addScript()
function of pageRenderSupport.
But it seems that :
- entities are filtered in addScript : if I write
pageRenderSupport.addScript(alert('');); in Java, the pop-up displays
gt; ;
- moreover, if I set @Meta(tapestry.response-content-type=text/xml),
scripts added by addScript() are no longer executed.
So... Well, what am I doing wrong ? And how can I correct it ? At least,
I need to be able to use , etc in addScript.
Chris, I know that you have a hard time with all these questions, have
you any advice ?
In a perfect world, I really like to be able to define block in the
template, with Javascript in them, and pass them to addScript... Or
perhaps Tapestry may have a javascriptblock component, with it's content
automagically added to Tapestry.onDOMLoaded...
Thank in advance,

[T5] Grid : how to overload a cell whose name is know at runtime ?
Hello,
I would like to overload a grid cell. It's easy if I know the name of
the cell, say mycell :
8---
t:grid t:source=mysource ...
t:parameter name=mycellCell
here goes the template for mycell
/t:parameter
/t:grid
8---
My problem is that I want to overload only some cells, based on their
name, but the name is only kown at runtime.
I thought that I could do something like that :
8---
t:grid t:source=mysource ...
t:parameter name=${theName}Cell
here goes the template for ${theName}
/t:parameter
/t:grid
8---
But it doesn't work. Somebody know how to achieve that ? And for my
culture, why it doesn't work ? (something to do with parameter binding
and evaluation order, I suppose)
Thanks in advance

Re: [T5] overriding persistence strategy of all fields to conversation strategy

But in library, components just use the default persistence strategy. If a strategy is specified, it should be for a meaningful reason. Perhaps they have define there own strategy. So I think that you should just give the possibility to change the default strategy, not impose it. Moreover, libraries may evolve to use your strategy with their constrains - nobody better that the dev of a component know what may break with a modification. making it easy to use for developers is also a goal.

Re: T5: @OnEvent and onActivate
Angelo Chen wrote:
Hi,
Can we use @OnEvent to annotate a onActivate method, say:
@OnEvent(???)
void myActivate() {
}
I'm not sure I understand what you want to do.
The @OnEvent tag signal a handler for an Event. The method annotated may
have any name you want, but you SHOULD avoid Tapestry reserved name (I
think it was said that an exception should be raised if a conventional
method name is annotated).
. Event handlers can be used in page or components,
The onActivate method represent the method(s) called at the page
activation. Page activation is a special phase before page rendering
which deals with the context of the page (for example get parameters).
It's an important phase because it is the last in the response process
where you can send a redirect or a non HTML response (see the PDF
tutorial for example).
The activation phase is *always* done in a page, even if no onActivate
method deals with it.
So,
- you can use @onEvent on any method you want but you SHOULD avoid
reserved name ;
- onActivate is not an event handler.
What do you want to do ?

Let's say a ListPerson in a situation where we want the user to be able to edit the name and surname of all in a single request. What could be the more elegant solution ? 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] remove [red] remove add 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).

error image near fields and text browser : remove it ?
Hello, Near each fields in a form, there is an error image with css classes t-error-icon and t-invisible. The t-invisible class is removed if the field is in error, to signal what field is faulty. This behaviour is problematic with text browser. Well, you will say that nobody use them anymore, but in the case of blinded people, they use an equivalent that read pages for them, and don't care of the CSS. The problem is that for this kind of browser, all fields seems to be on fault since the first access to the form. So it would be great if there were a way to remove this image, and add it *only* when there is actually an error. And javascript validate can add the img node if needed.

[T5] Re-inject or inherit services in children ?
Hello ! My project is a little more advanced, so I spent some time refactoring the code. Along this refactoring, I saw that I have a lot if component and class that inherit a base page (yes, that's why I have a base page ;). I inject on this page some quite common services (for example, an authorization service). So, what is the best pattern, in regard of Tapestry 5, for a page or component that extends my page base : inject (again) the services, or get it from the parent (what suppose that these services have matching getter in the base page).

But as you said, it should be better suited to create new services than a base page for that, and only use them where they are needed. I kind of like the list of injections in my components ... it's kind of like a cast of characters in a play. And I completely agree with that. In each component, I use a really visible comment to hilight the injected services : just with that, I can (almost) know what the component is going to do, or at least what may be its side effects. So, it's a really good reason to inject services every time they are really need. Ok, so I should build more unit services, make some facade for logically linked services...

Re: Caching: dependency on session data [OT?]
Kaspar Fischer wrote: Dear All, Helllo, If so, my next question is slightly off-topic: How can I implement caching?

Are there any caching libraries out there that accomplish this? I haven't any experience in caching a webapp, but perhaps that you can have another solution that is : * cache the object pulled from the DB. For that, you can rely upon the caching system of your ORM, or use a caching library (for instance EhCache : http://ehcache.sourceforge.net).

Re: BeanEditForm and collections
Kevin Menard wrote: Does anyone have any hints on getting BeanEditForm to play nicely with collections? For now, BeanEditor (or BeanEditForm) is not really aware of collection as a property. I think it's in the todo list (T5 still alpha, etc ;) So, for now I think that the only solution is to code the matching property editor model or bean model (dependanding of what you want) In my case, when I have a bean with both simple properties and collection properties, I decompose its form with several beaneditor : - one for all the simple properties ; - one for each property witch is a collection. For the second case, I generate a beanmodel for a fake bean in witch each entity of the collection is a property of the fake bean (in my case, I deal only with List, it would be easy to do the same for Map, harder to deal with unordered collection). So, I have a ListStringEditor that permits to edit, add and remove the strings in a list. The properties editor for these string are the standard one. Exemple : I have a bean named Eschema attributes that is composed with several simple properties and a list of possible values. According to the explained decomposition, the EschemaAttributeEditor template looks like : 8-- t:container class=attribute_details xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd; t:beaneditor object=attributeDefinition model=model/ t:wui-commons.eschema.listeditor object=attributeDefinition.possibleValues elementClass=literal:org.interldap.ldap.objects.IByteString/ /t:container 8-- The generated html looks like : 8-- [[propertyX]] [[propertyY]] [[propertyZ]] [[possibleValue1]] [delete] [[possibleValue2]] [delete] [add] 8-- (delete and add are buttons, [[..]] are text fields or whatever the propertyeditor say it is). You can look at the Java code her : http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/trunk wui-common/src/main/java/org/interldap/wui/t5lib/components/eschema Hum. It seems that the browseCVS is again broken, so you should have to checkout the code : # svn checkout svn://svn.forge.objectweb.org/svnroot/interldap/interldap-wui-common/trunk wui-common and look at : The code that generates a BeanModel given a list : - wui-common/src/main/java/org/interldap/wui/t5lib/data/ListObjectBeanModelSource.java - wui-common/src/main/java/org/interldap/wui/t5lib/data/ListObjectPropertyConduit.java The use case example : * the BeanEditor for the list, with the add/delete buttons and logic : - wui-common/src/main/java/org/interldap/wui/t5lib/components/eschema/ListEditor.java - wui-common/src/main/resources/org/interldap/wui/t5lib/components/eschema/ListEditor.tml * the eschema attribute editor that uses the ListEditor : - wui-common/src/main/java/org/interldap/wui/t5lib/components/eschema/ListEditor.java - wui-common/src/main/resources/org/interldap/wui/t5lib/components/eschema/EditAttribute.tml And yes, I agree that it is over complicated for a simple need, but I couldn't wait for a tapestry 5 native implementation.

Re: [T5] BeanEditForm validations
Kevin Menard wrote: Hi, Hello, Is there anyway to configure validation for a BeanEditForm other than with the Validate annotation? I'd like to have validation, but really can't apply the annotations because I'm working with classes coming out of a library. I see at least two other way, one simple and one other a little more complicate. The first one is to use the validate parameter in a property editor override in the BeanEditForm template. See Property Editor Overrides in http://tapestry.apache.org/tapestry5/tapestry-core/guide/beaneditform.html You might also add your custom property editors with their template (and so their fields with validate parameter). The other one is the programmatic way, but you should not need it for common use of BeanEditForm. If you want to customize globaly the validation proces, you may extend the PropertyEditor component and play with FieldValidator and fieldValidatorSource service. You also will have to extend the BeanEditor component template to use you new property editor, and the beanEditForm so that it uses the new BeanEditor. If you want, I have an example of such a thing here : http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/trunk/src/main/java/org/interldap/wui/t5lib/components/ldapentry/ A brief description : * MyPropertyEditor is just a copypast of T5 PropretyEditor, with some visibility change on methods, you may forget it ; * ** AttributeEditor ** is a special editor for the kind of attribute I have to deal with in my app. It extends MyPropertyEditor (read PropertyEditor) and It is the intersting component in which my personal validation process is done. Basically, I want to add a required validator if the attribute has a mandatory parameter set to true. * AttributeBeanEditor EntryBeanEditor. I think they are not to interesting for what you want to do, but if you look to their template, you will see that AttributeBeanEditor calls AttributeEditor and that EntryBeanEditor calls AttributeBeanEditor.

More component / event oriented : * JSF : after EJB 2, the new over-engineered Sun tech ... Well, Seam seems to be the best approach to JSF.

Some friends of mine love it, but something with the statefull by default behaviour dislike me (I never did Swing development, perhaps it's a reason) * Tapestry 5 : really simple and nice, I like the IoC (but I was doing Spring/Guice development for almost 6 month before discovering T5), the ease of doing new component. The big minus are : it's still alpha (and so it lacks polish, AJAX, basic components, etc), it lacks a big community/visibility, the migration path between major version is quite frightening (but it should be better from now).

form.recordError(fieldWitchCauseTheError, a text);
}

But I don't understand how I can find fieldWitchCauseTheError, I don't
see any method to access the list of field of the form (and I can't
inject fields because they are generated at runtime, or enclosed in
other components).
anybody know how can I access the fields of a form ?

Re: Recursion of components
Hello Todd, Todd Orr wrote: I'm also trying to perform this type of recursive structure. I don't agree that this makes anything simpler. Recursion is a powerful and concise tool for these situations. I will say that it is often abused, but this is a perfect use case. A recursive solution to this problem is far simpler and maybe more correct than this iterative approach. I read again my post and saw that I didn't express myself properly (put it on my low level in English). I should have write :The non-support of recursive structure seems to bring a lots of simplification with it _for Tapestry internal, replication and performance problematics_. It seems to be a design choice, and as I'm not a Tapestry developer, I can't explain exactly why it was done, even if replication/pool of pages seems to be around. I came from functional programming projects where this kind of structure is quite common, so personaly, I find that it's a real lake. First off, the proposed solution requires complicated logic. Fine, it's not rocket science, but the recursive alternative (if there was one in tap) is far easier to read and understand. From a tech-management point of view the simplicity of the code is a major factor in its long term maintainability as well as its bugginess. Secondly, the proposed solution requires adding raw HTML output to code. This may be a more esoteric and arguable point, but Tapestry excels in having a clear and easy to use separation between the view/presentation and the logic components of the application's construction. Again, with regards to maintainability, it is twice as hard to maintain code if the concerns are spread throughout conceptually separate pieces of code. If you look at the source code for for component, you will see that it is far from being trivial. It also deals with raw output, and different case are need if the loop is in a form or not... But the use of for component is quite simple. You could design a Tree component that handle this stuff and just use it elsewhere in a simple way. with a clear separation between template using this component and the component. It's what I did in a tree component : http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-t5/trunk/src/main/java/org/interldap/wui/tapestry/components/Tree.java?view=markuprev=97 Third, this approach makes it impossible for any node in the tree to contain any non-trivial nested components. I see that you can create links...wow. Kinda limiting if you ask me. This limits the usefulness and extendability of the code. If more complex functionality is required (lets say by a major client or some other critical business need) within this pseudo-recursive implementation it might force the developers to completely switch out frameworks to one more suitable for the job. This is a huge risk from a business perspective. Ok, so here, the problem is that the tree component is not well designed (or not as much generic as it should be). Perhaps a real tree component in standard lib would be good. But it has little to do with the lack of recursion structure, that is painful. A tree structure would be (at best) a bypass for this lack. -- Francois Armand Etudes Développements J2EE LINAGORA SA - http://www.linagora.com Tél.: +33 (0)1 58 18 68 28 --- InterLDAP - http://interldap.org FederID - http://www.federid.org/ Open Source identities management and federation - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I don't know how T4 works, but if it's like in T5, their is no support

So, for tree structure, you have to use a non-recursive algorithm (I
think that in your example, you wish to use a non-recursive preorder
traversal).
It's not really natural, but the non-support of recursive structure

How to add a List support for BeanEditor?
Dear list, It would be great if BeanEditor support collection and map properties, or at least List. Functionally, for this kink of properties, one wants to be able to add/remove elements from the collection and edit them. Programatically, it seems to be an hard problem... I would like to explore with you how to bring this support to bean editor, because I think that the need is real. For my personal example, I had to do that for a CRUD application on LDAP entries. LDAP entries are lists of attributes, and attributes are lists of values... To achieve my goal, I had to develop a complete specific component (base on the model of BeanEditor) which handle a specific entryBean. But the result seems to be quite specific and tricky (the code is available at http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-t5/trunk/src/main/java/org/interldap/wui/tapestry/components/ldapentry/EditForm.java?view=logrev=120 for the edit component, and http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-t5/trunk/src/main/java/org/interldap/wui/model/EntryBean.java?view=logrev=120 for the special bean, but this code is completely out of date in the _viewSVN_, the forge (ObjectWeb) is in migration and it seems to no go too smoothly... Thought, the svn is up to date.) Ok, so if you are interested, we may see what we want to do, and how we can help implement it. - Functionnaly, I wish to have that : I have a bean with a list of SomeType (say String) : ListString fruits; (for instance [apple, lemon]) I want that the beaneditor construct this interface ( where [...] is the editor matching String type) : 8--- [ apple ] _remove_this_fruit_ [ lemon ] _remove_this_fruit_ _Add_a_fruit_ 8--- so, the question are What are the major difficulties, and how can we implement that ? Perhaps it just a special editor, which handle list type, but I don't see how to coerce objects in the list, and how to get/set/add/delete them... any ideas would be appreciated :) Francois - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

When you have a component with parameter, you have two way to specify it

You can use list in context. For example, if you have a

list.add(plop);
list.add(new Integer(guess).toString());
return list;

In your :

Nick,
there is no difference whether your event method gets triggered upon
clicking a link or a button. Except that you can pass parameters like
an index when using actionlink. And that's exactly what you want.
Ok, but if the data are not transmitted to the server, we are not going
anywhere.
My use case was : I have a form with a list of text field, for each
field a delete (link|button), and a submit button.
I want that if an user modify some fields and then click to delete
(without submitting the form), the matching value is deleted _and_ other
modification are kept.
To achieve that, the field values have to be transmitted to the server,
what is not done with an action link.
So, Nick Westgate point out the good solution (I think), I just need to
be done ;)
Just to be sure : there is no other solution than to use javascipt to do
that ? I was thinking that as Tapestry handle the form action link, it
would be possible to add a context to submit button, as example :
:tform
t: submit t:id=context context=value
t: submit t:id=submit
/t:form
With submit from submit button mapped to action link
myformcomponent.form and context button mapped to
myformcomponent.form/value, and in Java code, context available as now
for action link : onSelectedFromContext(String value) {...}
But I have absolutely no idea on the feasibility of that.

Yeah, this is exactly what I have implemented. Eventually a shared hidden

support for this yet. Also a context that is a list of objects was my
plan,
but the context passivation is all internal and relies on the
TypeCoercer
stuff which is a bit involved. This should do for a first cut.
Well, I need at least to deals with ListString argument, even if it is
as a (two) simple way, so a change your code as wrote at the end of the

an action link (ex: value0/value1/value2) so that in the event

robust, it would be better to use TypeCoercer and some other remarks,

Thank you François,

Oups ^^
I think a listener concept is missing !
Another example :

t:actionlink t:id=want2beRich context=falseYES/t:actionlink

Ok, now I better understand your concern. You would have a kind of group
notion for action event ?
Somethink like that :

t:actionlink t:gid=want2beRich t:id=foo
context=trueYES/t:actionlink
t:actionlink t:gid=want2beRich t:id=bar
context=falseYES/t:actionlink
8--
And the event handler onActionFromFoo match first link,
onActionFromBar match second link, and onActionFromWant2beRich match
both.
I don't think this kink of feature exists for now, but you can take
advantage of event bubbling to achieve your need : just create a
trivial component Want2beRich :
8--
java:
public class Want2beRich {}
html:
div xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd;
t:actionlink context=trueYES/t:actionlink
t:actionlink context=falseNO/t:actionlink
/div
8--
and use it on your parent component/page : t:want2berich/, with the
corresponding event handler onActionFromWant2berich.
Well, it seems that the risk is to have a batch of component with this
solution...
Nonetheless, I hope it will help you.

There's an existing bug for this. I'm not sure how fixable it's going
to be; welcome to the implementation nitty gritty of generic types and
type erasure. Just cause you don't see the typecasts doesn't mean the
compiler has put them there.
Here's a challenge: what if there was a createWidget() method on your
class. How would you implement it, to create an instance of the
correct class? You can't do a new T() (the compiler won't let you,
since it doesn't know what T is).
As you say, the wonderful type erasure feature implies that you have
to have more information about your type. For instance, you need to pass
a ClassT type to your create() method. Actually, it's not really an
acceptable solution, but the sole workaround I know (if somebody as
another idea, I would be glad to use it).
After that, you can use reflection :
8-
public class EditWidgetPageT extends Widget {
T widget;
T create(ClassT type) {
widget = type..newInstance();
}
}

A bunch of infos are available at www.angelikalanger.com FAQs, and more
precisely about your concern :

Well, this sentence is not true.
You may ask users to implement a factory interface for Class they
intend to use as parameter type for the bean component source object.
The interface should be like that :
8--
interface FactoryT {
T create();
}
8--
And then you just call the create() implementation.
The problem is that that solution is very error prone : the interface
base implementation has to be overridden by each subclass or you will
end with the same type problem.
So, it seems to be a wore solution than the other one...

[T5] How to retrieve the id of an event emitter in handler method ?
Hello, I would like to know how I can retrieve the ID of the component which triggered an even when I'm in an event handler method ? Well, perhaps that my problem is not this problem, so there is a little background to help you to decide... In my application, I have to create a component to manage an editable list of string. The available (functional) actions are add a string, remove a string, edit string. I need to present the edit form so that all action can be done in the same page : 8--- (note: string? are input text field) | string1 | _delete_ | string2 | _delete_ | string3 | _delete_ _add_a_value _submit_change_ _reset_ 8--- So, there's no real problem to do this : in the html template, I used a form component, with a loop component which goes through the list. I want that if an user edit some field and then want to add/delete a value, his modification are kept, so _add_a_value_ and _delete_ are submit button. The template looks like : 8--- t:loop t:source=range t:value=index p input t:type=TextField/ t:submit t:id=remove value=Remove/ /p /t:loop t:submit t:id=add value=Add/ ... 8--- In the Java code, I have two event handler : onSelectedFromAdd() and onSelectedFromRemove(), and they are called when matching button are submitted. But for the delete button, I don't know which one was really submitted. I would be happy if I can retrieve the id of the submitted remove: I can generate it so that I can retrieve the matching value to remove. An other option would be to pass a context to the submit event, but I don't think it's possible... So, if you have any idea to help me, they will be well-appreciated...

T5 : wiki howto contribute custom propertyeditblock for beaneditform
Hello guys, I have implemented an example of a custom propertyEditBlock for the bean component, to see how it could work. As I think that I'm not the only one in that need, I contribute an how-to to explain what I understand : http://wiki.apache.org/tapestry/Tapestry5HowToCreateAPropertyEditBlock In fact, that block editor is quite simple (it's a kind of toy example for a component which have to work with beanPropertyEditor), but perhaps it may help other user to begin with BeanPropertyEditor implementation. Its goal is to generate a drop down list from a list of strings (it should be easy to generalize to type T, as explain in another wiki how to). The list of options is encapsulated in an object whose type is used in contributeDefaultDataTypeAnalyzer. String of the list are used as option for the select. The links to the complete code seem to be broken for know because the viewcvs of the Object Web forge hosting the code is not up to date with the last commits, but it should be resolve as soon as batch runs. Don't hesitate to ask me if you want some precisions or if you don't even understand a single word of what I wrote, my English is quite rough...

Re: T5 class reloading
Le mercredi 30 mai 2007 à 07:28 +, Martin Grotzke a écrit : For me changed classes are not picked up automatically, when running mvn jetty6:run... If it's working for you, what's your setup, or did you do anything special to support class reloading? Is it connected with a context reload of your servlet container (what AFAICS should not be necessary)? Well... I encounter some strange behaviour with mvn jetty:run and class reloading. It works perfectly at my work, and jetty fire some exception about unimplemented class reloading functionality in fresh install of eclipse 3.2 at home. So, the way that seems to just work is to use jetty 5 + jetty launcher plugin, as show in the tutorial ( http://tapestry.apache.org/tapestry5/t5-tutorial.pdf ), and let mvn apart for that task. If some one has a procedure to have mvn jetty:run + jetty 6 (0 or 1) + class/template reloading work, or just can explain what factors make it work or not, I will be glad to know them.

[T5] xforms component ?
Hello, I continue my investigation with Tapestry 5 and enjoy it. My targeted application will have to use a lot of XForms forms and I wonder if an Xforms support is envisaged in Tapestry 5, perhaps as a kind of BeanEditor component. Well, perhaps that an XForms integration with T5 is a whole project, and quite a huge task. Moreover, all that's XML is not too in the Tapestry 5 way... Nevertheless I would be very interested with any information on how XForms and Tapestry 5 could cohabited.

Re: [T5] Tree component and recursive component ?

I was just thinking about some of this on the way in.
If you @Inject the ServiceResources into your Tree component, you can ask it
to generate action links for you. Handy!
Well, I succeeded in doing something... And Tapestry 5 is just amazing !
Now, I have a Tree component witch take a DefaultMutableTreeNode as
parameter and walk trough it in pre-order order, adding element at each
level swich, and write what I want for each node.
For exemple, if myTree has this structure :
8-
root
|- node1
||- node11
|`- node12
|- node2
`- node3
8-
and it is passed to my component in a template such as this :
8-
t:tree source=mytree currentnode=node levelelement=ul
li
t:actionlink context=node.toString()
${node.toString()}
/t:actionlink
/li
/t:tree
8-
The rendered html will be :
8-
ul
lia..root/ali
ul
lia..node1/ali
ul
lia..node11/ali
lia..node12/ali
/ul
lia..node2/ali
lia..node3/ali
/ul

I'm a total beginner to T5 but that took me not a full day to understand
T5 base principles and code it... Wow. Really, Tapestry 5 is exiting.
Thanks for it, and I can't wait for the final version :)

[T5] Tree component and recursive component ?
Hello everybody, I'm a beginner with Tapestry (and T5), and test it as a possible framework for a futur application. I have tested T5 for 3 days and for now, I'm really impressed by it. But I came to my first real problem (all others are related with the lack of documentation, which is quite normal for an alpha release). My application deals with LDAP directories, so I need to managed tree structures all the time. But I saw that recursive component are not allowed in T5, I think it is due to the Principal 1 -- Static Structure of T5. So, my question is : is there a way of implementing recursive component ? If not, is there an existing component implementing a non-recursive tree walk ? And if not, have you some advices about doing such a component in T5 (say I know an algorithm for non-recursive tree walk, what are the best practice in T5 ?) Thanks you for your work, it's already quite impressive, and I hope it will continue in this path. A last remark from a new tapestry(ies ?) user : it's a bit disturbing to have 3 or 4 version of tapestry cohabiting, compatible or perhaps not... It's a pain to find valid information, or just to find where to look. Ok, Tapestry already has a (great) history, but T5 is something really new, different and exiting. I think it would be great that T5 will be clearly presented as that, with its own user list, community, wiki, etc, and not as just a new version of an old framework (even if this old framework was a breakthrough one, because t5 is a new breakthrough, isn't it ?) But well, it's just my user point of view ;) Francois - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Ok, I found that : http://tapestry.apache.org/tapestry5/tapestry-core/guide/dom.html and I can render my tree with ul/li tags thanks to MarkupWriter. But now, I want to add actionlink around each node content (the string enclosed by li tags). How can I do that ? I think I can copy the code from ActionLink, but perhaps there is a better method (well... Now that I begin to play with MarkupWriter, I certainly have to use it for everything...).
