Re: Injection javascript code - AjaxResponseRenderer vs JavaScriptSupport
Just further to this, here is the utility service I use to wrap JS calls
from any context (which helps leverage re-usable code).
ie using this avoids having to change between AjaxResponseRenderer and
JavaScriptSupport depending on the context (XHR/phase).
public class JavaScriptHelperImpl implements JavaScriptHelper
{
@Inject
private Environment env;
@Inject
private AjaxResponseRenderer ajaxResponseRenderer;
@Inject
private Request request;
@Inject
private JavaScriptSupport jsSupport;
@Override
public void addScript(final InitializationPriority priority, final
String format, final Object... args)
{
if (!request.isXHR()
// test environment for existence of JS support - ie only use
AjaxResponseRenderer if xhr AND not render phase
|| env.peek(JavaScriptSupport.class) != null)
{
jsSupport.addScript(priority, format, args);
return;
}
ajaxResponseRenderer.addCallback(new JavaScriptCallback()
{
@Override
public void run(JavaScriptSupport javascriptSupport)
{
javascriptSupport.addScript(priority, format, args);
}
});
}
}

(call set yourself) from within your component event handler...
hope that helps, paul.

Hi Paul,
Hm... yea this appears to be the same problem that I am having. The set

triggered (the add script part in the run method that is)

Re: Injection javascript code - AjaxResponseRenderer vs JavaScriptSupport
i'm assuming this 'afterrender' is within a component which is within a
zone being updated via an ajax request/response?
if so, is this the same as the issue i logged?:
https://issues.apache.org/jira/browse/TAP5-1870
does your set method get called at all?

(would like to avoid setting up a new variable in the class if possible).
I think that first apprach has worked when I tried it before but at that
time it was in the ajax request, so in the method that handled the ajax
response. Now I am just refreshing the zone in which there is a component
that has that after render method.
Anyhow what should be the best way for this?
Cheers and tnx all

Re: Injection javascript code - AjaxResponseRenderer vs JavaScriptSupport
AjaxResponseRenderer is only available for Ajax requests. JavaScriptSupport
is available for non Ajax requests.
I'm guessing either you didn't specify a zone on your eventlink / form or
you have a JavaScript error on your page (meaning tapestry can't decorate
your links with Ajax actions)

Re: Injection javascript code - AjaxResponseRenderer vs JavaScriptSupport
My scenario is that I have a link (there is zone parameter) that refreshes
the zone. Now in this zone there is a component in which there is a method
@AfterRender
public void set(){
ajaxResponseRenderer.addCallback(new JavaScriptCallback() {
@Override
public void run(JavaScriptSupport javascriptSupport) {
javascriptSupport.addScript(alert(%s),
selectedComponent.getId());
}
})
}
Now this method gets triggered but the run part is never actually triggered.
If I use the JavaScriptSupport instead of the AjaxResponseRenderer it works
without a problem. But I would expect that the first approach works just as
well.
I did try this approach in the method that gets triggered for the ajax
request and then this works but my problem is that this part needs to be in
the component and then I need to use (right?) @AfterRender.
tnx all

Re: Injection javascript code - AjaxResponseRenderer vs JavaScriptSupport
As Lance said, you need to use JavascriptSupport when preparing a
non-ajax response, and AjaxResponseRenderer when you are...
if (request.isXHR())
{
// use AjaxResponseRenderer
}
else
{
// use JavascriptSupport
}
however if the bug (https://issues.apache.org/jira/browse/TAP5-1870 )
affects your case too then afterrender is not being triggered
automatically by the framework and you need to execute the method (call
set yourself) from within your component event handler...
hope that helps, paul.
