Re: Live support solution
I found that the problem accurs in the onActivate() function. Our pages give information between eachotter trought the activationcontext.

Re: Live support solution
I've created an issue here https://github.com/uklance/tapestry-cometd/issues/55
Re: Live support solution
the activate is somthing like:
Object onActivate(context)
{
if(context.count()0)
do somthing
else
redirect to other page
}
my onchat method is unchanged from your demo project.
I'm now trying to add an eventlink to the list of users to make 1v1 chat
possible by changing the topic.
Try adding an eventlink in the loop of users in your demo project.
t:block id=chatUsersBlock
ul
t:loop source=chatUsers value=currentUser
lit:eventlink event=user
context=${currentUser}${currentUser}/eventlink/li
/t:loop
/ul
/t:block
and in java
void onUser(String user){
system.out.println(user)
}
this also gives the encodeURL error. (is this the same error as what you
said?)
any other idea on how to do this?

Handling onEvent change from a Select component
After a lot of Googling around I'm unable to find a solution to my problem. I
want to handle the change event from a Select Component. I'm creating a bunch
of these components in a loop:
t:select t:id=type model=cardTypeModel encoder=cardTypeEncoder
value=cubeCard.cardType blankOption=never/
And I've got the following handler declaration:
@OnEvent(component=type, value = change)
public Object onChangeOfCardType(String value) {
System.out.println(onChange!!!);
return cardTypeZone.getBody();
}
Ideally I want to provide some context to this handler too so that it knows
which CardType to update (i.e. which Select the event came from). The handler
just isn't getting called at the moment, what am I doing wrong?
@BeginRender equivalent for component AJAX events
I have a component that includes a zone - the zone is periodically refreshed using the ZoneRefresh mixin. Is there any equivalent to @BeginRender that I can use to set up data to support the zone re-rendering? @BeginRender methods are called when the page renders, but they're not called when the zone re-renders via ajax. The only event I've found that gets called is @PageAttached, but of course this is deprecated. Any tips would be appreciated! Gratefully, Michael
Re: Handling onEvent change from a Select component
Hi Ben!
I am using the tapestry-jquery mixin for this:
tml:
t:select t:id=yourId model=yourModel encoder=yourEncoder
t:validate=required value=yourValue
t:mixins=jquery/bind bind.context=${yourValue.pk}
bind.event=yourSelectionChanged bind.eventType=change/
page:
public Object onYourSelectionChanged(final long pk)
{
System.out.println(pk);
return null;
}
so any change of the select input control triggers change which calls
the yourSelectionChanged method, which is named
onYourSelectionChanged in java by tapestry convention. I believe you
can use [${yourValue.pk}, ${whateverId}] to pass multiple arguments to
your method, too (be careful: this is just my gut feeling, never tried it)

Re: mixin script added in afterrender not fired for xhr requests
Turned out this was because I was adding the script via
ajaxResponseRenderer.addCallback which used to be the recommended
approach.
JavascriptSupport now handles partial renders via partialMode (if you
look at the source).
Perhaps ajaxResponseRenderer.addCallback should be deprecated now?

Hi all,
Can someone familiar with the mixin lifecycle please advise me:
I have a mixin which triggers some javascript from 'afterRender'. I
do this in 'afterRender' because I need the field's clientId to be

It works great if the Field it attaches to is rendered when the page
is first rendered, however if it is rendered as part of a zone
update/xhr request, the script is never sent to the client.
I have breakpointed the JavaScriptCallback and while it is
successfully added to the ajaxResponseRenderer, it is never called.
Thanks for advice!
code Eg:
public class MyMixin

void afterRender()
{
addScript(MyMixin.create('%s', '%s');,
field.getClientId(), myVariable);
}

Re: mixin script added in afterrender not fired for xhr requests
Actually, no .. I cannot just use JavascriptSupport.addScript
everywhere I used to use AjaxResponseRenderer.addCallback
In XHR cases I get: UnknownValueException - No object of type
org.apache.tapestry5.services.javascript.JavaScriptSupport is available
from the Environment.
I wonder why this is not the case in the Mixin's afterRender.. ?
This is getting confusing because calling
AjaxResponseRenderer.addCallback does not work in the case of the
Mixin.afterRender, however JavascriptSupport does not work in XHR
event handlers.
I imagine this has to do with the render phase somehow... would love to
hear some experts opinion...
thanks, p.

Turned out this was because I was adding the script via

approach.
JavascriptSupport now handles partial renders via partialMode (if
you look at the source).
Perhaps ajaxResponseRenderer.addCallback should be deprecated now?

Hi all,
Can someone familiar with the mixin lifecycle please advise me:
I have a mixin which triggers some javascript from 'afterRender'. I
do this in 'afterRender' because I need the field's clientId to be
initialised.
It works great if the Field it attaches to is rendered when the
page is first rendered, however if it is rendered as part of a zone
update/xhr request, the script is never sent to the client.
I have breakpointed the JavaScriptCallback and while it is
successfully added to the ajaxResponseRenderer, it is never called.
Thanks for advice!
code Eg:
public class MyMixin
{
...
void afterRender()
{
addScript(MyMixin.create('%s', '%s');,
field.getClientId(), myVariable);
}
private void addScript(final String format, final Object... args)
{
if (!request.isXHR())
{
jsSupport.addScript(InitializationPriority.NORMAL, format, args);
return;
}
ajaxResponseRenderer.addCallback(new JavaScriptCallback()
{
@Override
public void run(JavaScriptSupport javascriptSupport)
{
javascriptSupport.addScript(InitializationPriority.NORMAL, format,
args);
}
});
}
}
