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);
}
});
}
}
