T5 / Ajax / What controls XHR ?
Hi! We have trouble with zone updates via an ActionLink in Internet Explorer (7 8). And right now this is stopping is from launchin our new site For some reason the request.isXHR() is fasle when the request comes from IE. A newbie question what so ever. What controls the XHR flag? It must be something in .. javascript:Tapestry.waitForPage(event); Right? Another strange thing is that an actionlink within a zone does not have a onClick attribute after a zone update (according to firebug) but works anyway! When page is first rendeerd === a id=forgotPassword2 href=sv/register.telllayout.forgotpassword2 onclick=javascript:Tapestry.waitForPage(event);Glömt lösenordet?/a After the zone has been updated (according to firebug) === a id=forgotPassword2-12596c1dd00 href= /sv/register.telllayout.forgotpassword2Glömt lösenordet?/a Thanks in advance!

Re: T5 / Ajax / What controls XHR ?
Try analyzing the real request serverside. See RequestImpl.isXHR(). Check out which headers are set. On Wed, Dec 16, 2009 at 10:19 AM, Gunnar Eketrapp gunnar.eketr...@gmail.com wrote: Hi!

Re: T5 / Ajax / ID generation
Already had this problem and I'm still asking myself if it is a good thing to not let the developper controls the clientId. I tend to think it should be the matter of the developper, not of the framework.

T5 / Ajax / ID generation
Hi! We have a login form within a div that is initially hided and slided out by javascript when clicking on a login button. Within this div we use aja to replace the login form with a request forgotton password etc etc. My problem now is when going back from the request forgotton password look an regenerating the login fields T5 creates id's like ... id=password-837654873 ... which we need T5 not to since we have jaavascript that dependes on knowing the ids of these fields. Is there any way to prevent T5 from adding these numbers. The initally fields have been replaced so it should be safe to reuse the id names !!! (?). Thanks in advance, Gunnar Eketrapp

T5: Ajax response content-tpye
Hi All! I would like to change the content-type of the ajax response, when rendering a component from an ajax request. The content-type is 'application/json' and it need to be 'plain/text'. We develop an ip-tv middleware and the setTopBox's browser (Opera gogi) can not understand the application/json content-type (I think it treats the response as binary data). I handle the ajax response with my own javascript code, so 'plain/text' would be fine. I see from the source code that the mime-type's hard coded at the InternalConstants.JSON_MIME_TYPE variable, so i don't know how to change it. Anyone has idea how to accomplish this?

T5 AJAX
Hi I'm considering to move to T5 for a major new project. I evaluated T4 at some length a couple of years ago but went a different way for my needs at the time. We have experience with JQuery. I understand that T5 comes with prototype and scriptaculous support. How easy is it to replace those with Jquery? Or is it possible for them to 'coexist'? Does anyone have any specific experience of using Jquery and T5?

Re: T5: AJAX ActionLink exception if clicked as page loads
I ran into this problem myself. Is it possible to listen for an event that says Tapestry javascript has finished initializing the page? The scenario of users clicking links before they are decorated with ajax javascript is very common, so there should be a built-in best-practice solution for this. I know I could solve it server side by checking for isXHR, but I don't think the case of users being faster thinkers than the CPU should be a natural part of my graceful degredation. Users without proper XHR support should. I would like to be able to hide my links until they are ajax-enabled. Or implement some other trick to prevent this bug from happening. But I guess this would be pretty hard if I'm not able to track the status of the Tapestry init script? I could just use the Prototype dom loaded event, and add a 2 second timeout to be relatively sure, but it ain't exactly pretty :) Regards Inge On Mon, Sep 8, 2008 at 2:58 PM, luna_guo [EMAIL PROTECTED] wrote: Geoff It's ok to return a block object in a action handler method,but you can't use the type Block,it will throw exceptions.You should use Object instead. /luna -- View this message in context: http://www.nabble.com/T5%3A-AJAX-ActionLink-exception-if-clicked-as-page-loads-tp19346336p19372125.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [T5] Ajax And Zones
So am I dead in the water here? Sounds like this functionality isn't supported in T5? Seems strange that Tapestry 5 requires an INPUT field to be contained within a Form, and AJAX uses Zones, and you can not combine the two. So basically, AJAX functionality in T5 should only be used with straight text and HTML, no input fields. In my situation, the AJAX component doesn't contain a Form, but the components container may, so how do you use AJAX Zones with forms...for example, dynamic content.

[T5] Ajax And Zones
Greetings,
I have a component which displays a header and body contents, where the
contents are collapsed via AJAX support. The component is a DIV which wraps
a table that contains the header, AJAX block and Zone. There is an
ActionLink which is used to invoke the AJAX method that returns the AJAX
block to be rendered in the Zone via a delegate component. The basic AJAX
concept was derived from the following example:
http://202.177.217.122:8080/jumpstart/examples/javascript/ajax
Everything is ok and the contents are not rendered when the AJAX ActionLink
is invoked. That is done by returning null from the event handler. The
problem occurs when the event handler returns the AJAX block to be rendered
again (i.e.: expand the contents). Note, that the component itself is
wrapped within a form on the page. I recieve the following error after the
AJAX method exists and returns a valid Block component:
No object of type org.apache.tapestry5.services.FormSupport is available
from the Environment. Available types are
org.apache.tapestry5.RenderSupport,

[T5] AJAX and partial updates of forms ? [Zone AjaxFormLoop FormInjector FormFragment and the like]
Hello guys, I think I really need some clarification on all the things around partial update of a form. To begin, I read a lot of topic on this subject on the ml, all the doc available on the site and the example for T5 test suite, but I just don't get it, and I believe I'm not the only one in this case. My need is quite simple : I want to know how to update a full zone (that contains fields) inside a form given some field's value or action in the same form. Typical example are a select that update other fields availability, a radio button that enable some some more datas, etc. I'm aware of some workaround or specific case (a select can update an other select thanks to the onEvent mixin of t5-component lib), as am I of some related bug as https://issues.apache.org/jira/browse/TAP5-138 (add a zone parameter in select), but I really need a more general solution. What I have tried first is to simply add a zone in the form [1], but I get No object of type org.apache.tapestry5.services.FormSupport is available from the Environment. Afterward, I tried to use forminjector, formfrogment, ajaxformloop (which works great in the special context of adding/removing an unique row of some kind), and nothing seems to work for this use case. So. Is somebody aware of a way to do it ? Where is the triggerzone mixin that take an action (onselect, onchage, etc) and can be add to our component ? Where is the ZoneForm that can be put inside a form ? I would like this thread can lead to some kind of reference on the subject, so that an howto can be written on this topic. Thanks in advance for the help !

T5: AJAX ActionLink exception if clicked as page loads
Is this a known problem? Is there a known solution? I have a page with 2 ActionLinks - the first link updates the whole page; the second link specifies a zone. If you click on the two links in quick succession then an exception is thrown. Alternatively, just Reload the page and click on the second link before the page has finished reloading and you'll get the same exception.

Re: T5: AJAX ActionLink exception if clicked as page loads
Hi Geoff, Tapestry doesn't hook up zones etc. until the DOM is loaded, so the link isn't an AJAX link at the time you click it. You can check Request#isXhr in your event handler to see if it's an AJAX request - if it's not you can't return a Block, so you'll have to figure out another way to do what needs to be done. -Filip On 2008-09-06 14:48, Geoff Callender wrote: Is this a known problem?

[T5] AJAX Tapestry Forms?
Hi there, as the title suggests, I want to submit a form without refreshing the page. I don't even want to refresh a zone, but I need to specify a javascript function handling the return value of my function. While this is quite easy with normal HTML forms, I don't want to break with Tapestry - especially with the validation, the automatic object updating and a couple of form components, but unfortunatly I have no clue where to start with and don't even know if it is possible. Any thoughts on this? (By the way, what I want to do is to put a Tapestry form in a Lightbox - which should just just close after the submit.) - Tobias - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

And again hi everyone,
I managed to ajaxify my forms - but I have a problem left with the
return value of my onSubmit function.
First to explain, to make AJAX possible, I use a slightly modified
Tapestry.linkZone:
--
function ajaxifyForm(element)
{
element = $(element); var successHandler = function(transport)
{
// outputting transport for debug reasons
};
if (element.tagName == FORM)
{
Tapestry.getFormEventManager(element).preventSubmission = true;
element.observe(Tapestry.FORM_PROCESS_SUBMIT_EVENT, function()
{
element.request({ onSuccess : successHandler, onFailure:
Tapestry.ajaxFailureHandler });
});
}
--
So far, it works quite nice, but transport.responseJSON was empty
despite my onSubmit returning a JSONObject.
Looking at the Firebug Console, I find this for the POST response:
{testkey:testvalue}{}
Obviously this isn't correct JSON - it adds a {} to my clean response.
Looking through the tapestry-core, I found
org.apache.tapestry5.internal.services.AjaxComponentEventRequestHandler,
and in line 106 a new JSONObject is created (which would be {}). After
i remove this (and the following) line, the response is just
{testkey:testvalue} - as it should be.
I spent some time with the debugger and it seems that
104: if (callback.isAborted()) return;
just doesn't get called, despite a ComponentResultProcessorWrapper
([...].internal.services, too) gets to handle a result without any
IOException. But strange, after the method in triggerContextEvent in
92 returns, the callback.aborted is false.
Anybody's got a clue what's going on here - or, even better, a solution?

Re: [T5] Ajax request and expired session
The response is empty because the session has expired, and objects
carried in session (specifically security details stored by acegi),
are not accessible anymore. So yes, it is easy just to check to see if
they are there or not, and set the header appropriately.
Thanks,

[T5] ajax graceful degradation
Hi,
I've used the zone and block components to create an ajax refreshed page
part.
When the user click the actionlink, the content of the zone is replaced
by the content of the block. It works great :)
But I'd like my page to gracefully degrade when javascript is turned off.
request.isXHR() works well, but how to replace the content of the zone
in a non-ajax request, that refresh the whole page ?
Here's the code:
private Block onActionFromModifyDisplay(){
if(!request.isXHR()){
//what to do here ?
return null;
}
return displayBlock;
}
Thx

Page instance or whatever redirect the user to a page instead of Block.

Objet : [T5] ajax graceful degradation
Hi,
I've used the zone and block components to create an ajax refreshed page
part.
When the user click the actionlink, the content of the zone is replaced
by the content of the block. It works great :)
But I'd like my page to gracefully degrade when javascript is turned off.
request.isXHR() works well, but how to replace the content of the zone
in a non-ajax request, that refresh the whole page ?
Here's the code:
private Block onActionFromModifyDisplay(){
if(!request.isXHR()){
//what to do here ?
return null;
}
return displayBlock;
}
Thx
Julien

RE: [T5] ajax graceful degradation
I think you must manage the non-XHR state by yourself, and for exemple use a
delegate component in your zone to display the block if Ajax is not supported
by the browser. Hope this helps !

Hello,
By returning null, the same page is reloaded.
But the content of my zone should be updated, replaced by the content of
the block component.

RE: T5 ajax zones example
Yeah, this is all fixed now in 5.0.13. Plus the AjaxFormLoop and issue I was
having with the select box doing a resort and updating a zone!
I'm pretty happy, except I'm stuck in meetings in the US all week and not doing
Tapestry dev... ho hum.
Good work Howard.

T5: Ajax periodic update
Hi list,
I'd like to know if there is a simple way to perform a periodic Ajax update
request.
I've invented hacked a solution using the Ajax.PeriodicalUpdater from
prototype.js. It involves putting an ActionLink on the page, giving it a
client id, making it invisible to the user (with display: none), and then
making a new Ajax.PeriodicalUpdater using the a.href from the ActionLink.
The result of this call is a string containing the content generated by the
Block element, which I must then parse. If I do not manipulate the
response, the Zone will contain something like { content : blah blah blah
}.
I'm not crazy about my solution, and, moreover, it results in a mysterious
403 Forbidden reply on some platforms.
Otherwise, having great fun with T5. Keep up the excellent work!
Regards,
Marc

Re: T5: Ajax update of one form field based on change to another form field?
Thank you VERY much. That works like a champ... except I keep getting
an exception in the log, though it doesn't affect the UI. Here's the
way I ran with your suggestions. First, the tml:
t:beaneditform t:id=beanEditForm object=propertiesBean
submitlabel=message:save-label
t:parameter name=type
t:label for=type/
t:select t:id=type value=propertiesBean.type
t:mixins=t5components/OnEvent event=change
onCompleteCallback=typeChanged/
/t:parameter
t:parameter name=port
t:label for=port/
t:textfield t:id=port value=propertiesBean.port/
/t:parameter
/t:beaneditform
script type=text/javascript
function typeChanged(response) {
$('port').value = response;
}
/script
Next, the page java:
StreamResponse onChangeFromType(String typeName) {
DatabaseType type = DatabaseType.valueOf(typeName);
return new TextStreamResponse(text/plain,
String.valueOf(type.getDefaultPort()));
}
And lastly, the exception:

Re: T5: Ajax update of one form field based on change to another form field?
Franz Amador wrote: Hi, all. I asked about this a while ago, and there was no good answer then, but I'm hoping that there are new options now. I have a bean that holds information about a database connection. I'm editing it with BeanEditForm. One of the fields is the database type, an enum that renders as a dropdown. Another field is the database-server port. When the user picks a database type from the dropdown, I want to update the database port to the default value for that database type (e.g. 1521 for Oracle), while leaving the other fields alone. Is there a good way to do this? I see there's now a zone parameter to BeanEditForm that causes the specified zone to be updated when the form is submitted. This sounds promising, but I don't see how to make it work for my case. 1) I would need to make the form auto-submit when the user picks a value from the dropdown. I don't know how to do that, but there must be a way. Why would you need to submit the form when a value is selected from the list? If you know the available DBs before hand, then you know the default ports. Store those as a client-side JSON object and use the select's onchange event. 2) I would need a way to prevent validation from complaining about missing or errant fields during the form auto-submit, but to have validation work normally during a regular form submit (via the submit button). 3) I would need the form to do an Ajax zone update on an auto-submit (for a zone containing the form itself), but not on a regular form submit. On the whole, I prefer Tapestry 5 to Wicket, but for Ajax, I think Wicket's approach has some advantages. In Wicket, you can register an event listener on a component (e.g. an on-change listener on a dropdown). When the event happens, the listener method gets passed a list to which it appends components that should be re-rendered. While tapestry's Ajax support is still in the oven, it has @OnEvent which does something similar. In my case, I'd append the database-port-field component to the list when the database-type enum changes value. This approach allows me to update multiple components anywhere on the page in response to any event, with no need for a special update-target-wrapper component like Zone.

It just appeared that that was the only way to use the zone parameter on BeanEditForm to get what I want. It looks like you're proposing two alternatives: 1) Do it all client-side using JavaScript: That would work for this case, since I do know the mapping from DB types to DB ports in advance. I see two flaws, however. The main one is that I have other, similar cases in mind in which I'd need server-side computation to update the form in response to field-change events. Second, I don't know JavaScript well and don't like it, so I'd really rather keep it neatly encapsulated in components that somebody else writes. 2) Use @OnEvent: Do form fields issue events, or is that planned for the future? If they do so now, could you tell me the event name for a drop-down selection-made event, or tell me how to find it for myself? I don't see any mention of events in the code for Select, AbstractField, or Field. Or do I need to use a mix-in?

Re: T5: Ajax update of one form field based on change to another form field?
Sorry I was vague on that, and I was referring to the t5components
OnEvent mixin
(http://87.193.218.134:8080/t5components/t5c-commons/ref/org/apache/tapestry/commons/mixins/OnEvent.html).
Here's a quick example of ajax-based data retrieval. Note that where I
use hard-coded strings, you'd be using your database information bean
(or whatever). First you need your template:
form t:type=form
t:select t:id=mySelect model=selectOptions
value=selected t:mixins=t5components/OnEvent
event=change onCompleteCallback=selectionChanged/
t:textfield value=port t:id=dbPort/
br/input t:type=submit/
/form
script type=text/javascript
function selectionChanged(response) {
$('dbPort').value = response;
}
/script
The first thing to notice is the use of the onevent mixin, and notice
the subsequent parameters (event=change and
onCompleteCallback=selectionChanged). The 'event' parameter notifies
the mixin of which client side event it should bind to, while the
'onCompleteCallback' parameter is the name of an in-scope javascript
function that will receive the ajax response from the server. Also
notice our hard-coded script block in which we declare the named handler
'selectionChanged' - in which we set the value of the field by id
'dbPort' (which if you look at the form, you'll see that we created a
textfield with that id). Now the event handler in the page class:
public StreamResponse onChangeFromMySelect(String value) {
logger.info( changed: + value);
return new TextStreamResponse(text/plain,
value.equals(Oracle) ? 1521 : 3306);
}
This is obviously a stupid implementation in that it tests for the
string Oracle and returns 1521, other wise 3306 as a plain-text
response, but it shows how to check for what was selected and how to
return something. Now if you fill in the simple missing parts of this,
you'll see that it works by retrieving values from the server based on
the selection in an asynchronous manner. The OnEvent mixin really opens
the door to a much wider potential of data binding, but by itself it
gives you some raw tools to do what you want.
As for Ajax support being still in the oven, I'm really hoping it's
coming out soon.
I imagine it will stop baking when web development methodologies stop
changing. I said 'in the oven' because there are still and handful unmet
goals outstanding in the ajax area. There are a few useful things now,
and I'd say you can bet on the fact that the innovative strides in the
ajax part will be as innovative as those in the rest of the framework.

T5: Ajax update of one form field based on change to another form field?
Hi, all. I asked about this a while ago, and there was no good answer then, but I'm hoping that there are new options now. I have a bean that holds information about a database connection. I'm editing it with BeanEditForm. One of the fields is the database type, an enum that renders as a dropdown. Another field is the database-server port. When the user picks a database type from the dropdown, I want to update the database port to the default value for that database type (e.g. 1521 for Oracle), while leaving the other fields alone. Is there a good way to do this? I see there's now a zone parameter to BeanEditForm that causes the specified zone to be updated when the form is submitted. This sounds promising, but I don't see how to make it work for my case. 1) I would need to make the form auto-submit when the user picks a value from the dropdown. I don't know how to do that, but there must be a way. 2) I would need a way to prevent validation from complaining about missing or errant fields during the form auto-submit, but to have validation work normally during a regular form submit (via the submit button). 3) I would need the form to do an Ajax zone update on an auto-submit (for a zone containing the form itself), but not on a regular form submit. On the whole, I prefer Tapestry 5 to Wicket, but for Ajax, I think Wicket's approach has some advantages. In Wicket, you can register an event listener on a component (e.g. an on-change listener on a dropdown). When the event happens, the listener method gets passed a list to which it appends components that should be re-rendered. In my case, I'd append the database-port-field component to the list when the database-type enum changes value. This approach allows me to update multiple components anywhere on the page in response to any event, with no need for a special update-target-wrapper component like Zone. (You do have to call setOutputMarkupId(true) when creating a component that can be rendered via Ajax.) I hope this doesn't come across as a Wicket is better than Tapestry taunt. I've experimented with both at some length, and I find Tapestry 5 tighter and leaner and faster.

Re: T5: ajax component ids with namespaces
After fiddling with protoype the $$ coupled with the !^ selector seems to
work. I'm including some custom helper code to accomplish getting an
element by id without regard to the tapestry id namespace. If this is/was
obvious or there is better solution, I apologize but hopefully this will be
helpful to others.
// gets the first element where the id begins with the 'id_starts_with'
argument.
function $G(id_starts_with)
{
return( $G_(id_starts_with)[0] );
}
// gets all elements where their id's begin with the 'id_starts_with'
argument.
function $G_(id_starts_with)
{
return( $$([id^='+id_starts_with+']) );
}
to get access to this T5 namespaced node :
form id=foo:1234 /
call
$G('foo')

T5: ajax component ids with namespaces
Hi All,
I recently updated to Tapestry 5.0.11 from 5.0.10 and unfortunately my
custom javascript calls are broken because component id's returned from ajax
calls now have a :# next to them. For example when I try to get a
reference to an object say $('foo') it doesn't exist because it is now
$('foo:12234') and this id changes on every ajax refresh.I read the post
from Howard about this being a namespace for ajax requests
(http://thread.gmane.org/gmane.comp.java.tapestry.user/59677/focus=59697)
but I'm a little confused as to how I get access to these nodes with scripts
now? Can the AJAX namespacing be turned off (globally or at the component
level)? Does anyone have a workaround for this?
Much thanks in adavanced,
B

RE: T5: AJAX Zone updating doesn't work correctly in IE
Thanks for the reply José, but I haven't got a nested zone. Unfortunately my

really not clear what on earth I'm going on about. I was really hoping to get a

Andy,
I already pointed out this problem, that doesnt seem to be browser related, but
merely due to T5 conception. Basically Howard answered that on a div refresh,
the id of the refreshed elements nested in that div are changed by T5 : a
timestamp based code is added, making them unique among the client DOM. If this
div contains itself another div, pointed by a link, then that link is lost. It
explains the page refresh, since your action link (or event link) points to
nothing.
Howard didnt make any clear statement about that, but it seems to me that
nesting Zones is not legal in T5, or at least needs some patching in order to
work properly.

I think you need to do this yourself, using the builtin AJAX facilities, rather than using any of the builtin validation facilities. Say you were looking to make sure a username was unique on signup. Place an actionlink beside the field (check availability). The actionlink would need context (the username). The actionlink can update a zone containing the text field, and which also has some hidden divs containing the validation messages (just as a field with regular validation would be decorated). Display/hide the validation message div based on a flag set by the actionlink handler (which would obviously check the db for username uniqueness). That would be my first try (there are some pieces in there which might not work the way I'm thinking) - you could also do it with a mixin (see the AutoComplete component).

Re: T5 ajax zones example
Hi,
this works perfect with the Firefox. With the Internet Explorer it gives by
triggering the submit button, the link works:
org.apache.tapestry.runtime.ComponentEventException
A component event handler method returned the value
[EMAIL PROTECTED] Return type
org.apache.tapestry.internal.structure.BlockImpl can not be handled.
Configured return types are java.lang.Class, java.lang.String, java.net.URL,
org.apache.tapestry.Link, org.apache.tapestry.StreamResponse,
org.apache.tapestry.runtime.Component.
Any idea?

Re: T5 ajax zones example
This example only works with 5.0.11.
I tried it with Internet Explorer just now and I see that the ajax form is
submitted and the form is updated (correct), but the click event appears to
go all the way to IE and the form is also submitted by IE. This is wrong,
and it is the cause for the ComponentEventException you get.
This is a bug.
So ajax with forms ( =my example) only works with gecko-based browser at the
moment.

I'm not sure that I understand what you mean?

[T5] AJAX form submit
Hi,
I have a form that needs to change the view in a zone on a page. So I
use the new (5.0.11-SNAPSHOT) form with a zone (fantastic stuff,
Howard!)
t:form t:id=choose zone=allocations
t:label for=liquidated
Show liquidated funds
/t:label
t:checkbox t:id=liquidated value=liquidatedShown
onClick=this.form.onsubmit()/
input type=submit value=Choose/
/t:form
t:zone t:id=allocations
t:delegate to=block:allocationsForm /
/t:zone
Rather than using the submit button, I want to submit the form when
the state of the checkbox changes. I discovered fairly quickly that
using 'this.form.submit()' posts directly and circumvents the
javascript, but some digging showed that this.form.onsubmit() does the
job.
This works fine, but I get a javascript error out of Tapestry.js:
The error is at line 159 below, because the event is undefined. Would
it be possible to check for an undefined event here? Or is there some
way in which I can add an event to the onSubmit()?
I'd appreciate any suggestions!
Cheers,
Adriaan

T5: Ajax update of BeanEditForm on drop-down select?
I'm using BeanEditForm to generate a form that includes a drop-down selector. I'd like to get an event when the user selects a value so I can update other fields in the form, preferably via a partial-page Ajax-style update. Is this possible? If so, is there an example I can look at? If not, is there a way to do this with a regular form? Thanks!
Re: T5: Ajax update of BeanEditForm on drop-down select?
This is coming soon, but it won't be part of BeanEditForm ... to get that level of interactivity will require that you spell out your individual fields and labels, along with extra components mixins to describe the Ajax functionality to Tapestry.

Re: T5: AJAX and Firefox doesn't work
somehow the bug doesn't appear anymore. I'm running 5.0.6 so it could be
related. I'll investigate once I encounter it again.

A strange thing happens.
following an example of returning a streamresponse based on a user-click,
this all works well in IE7 but not in Firefox. Instead firefox exectutes
the
action and the simply fires an onActivate-event rendering the action
useless
(the page is simply loaded again as if the action wasn't fired. )
Anyone knows whats happening here? (I know this may nog be
tapestry-related,
but I'm not sure. )

Re: T5 Ajax - Which Ajax/Javascript framework will be next?

T5 Ajax - Which Ajax/Javascript framework will be next?
Reading http://tapestry.apache.org/tapestry5/tapestry-core/guide/ajax.html I'm just wondering what Ajax/Javascript 'du jour' will be in T5.0.8 I thought that Dojo was *the* standard framework of choice of Tapestry.

Re: T5 Ajax - Which Ajax/Javascript framework will be next?
I'd say you are missing something: this is Tapestry 5. If I'm not mistaken prototype has been the choice since the beginning of T5 - hardly 'du jour'. There has been chatter here and there about having a pluggable system for using the JS of your choice, however I don't think this has received any official attention from Howard.

[T5] Ajax architecture
Hello, does anyone know if similar drawing exist for T5? http://www.icefaces.org/main/product/architecture.iface It is not meant to be provocative - I just need to be objective in my report for our future web framework. I am very well aware that ability to build custom components easily outweighs the number of prepared (available) components - but still... Regards, Borut
T5: Ajax, Releases
Hi, looking at T5's roadmap, it says ajax support will be in by summer 2007, is the ajax already part of some beta versions? and will soon be in a pre-release? and T5's final release is Fall, 2007, possible?

[T5] Ajax tests
Hi, I play with T5 and want to explore Ajax capacity. I need to know which service is responsible on the instantiation of a component. Is it possible to have a resume (classes implied) of how Tapestry process component instantiation. Thanks for any input ;)
