Re: T5: RenderSupport in XHR requests
If you have a form in the block that is being rendered then I've used the
PREPARE_FOR_RENDER event from the form to inject scripts.
Subcomponents get their render methods called during a partial render, I'm
not sure why the targeted component's render methods are not called.

Re: T5: RenderSupport in XHR requests
It would be tricky for some technical reasons.
You can return a new Renderable object that will act as a callback
from inside the partial rendering pipeline; inside the render()
method, the environment (including RenderSupport) will be properly
setup:
i.e.
Object onActionFromFoo()
{
return new Renderable() { public void render(MarkupWriter writer) {
renderSupport.addScript( . . . ); } };
}

Re: T5: RenderSupport in XHR requests
Thanks Howard. Is the availability of RenderSupport within component
event handlers a candidate for a new feature? Without such support I'm
not sure how an app can return JS code to be executed to the client as
the result of an action (ie a fired component event).

Re: T5: RenderSupport in XHR requests
It may not work from an event handler method, as its wired into place
for the partial page render.

T5: RenderSupport in XHR requests
Hello,
I was under the impression that the use of RenderSupport to add
javascript to an AJAX response was supported, and that scripts added in
such a context via addScript would be executed automatically via
tapestry.js when the response is received. Isn't that how it should work?
I'm using a form with a zone to implement a "send link to friend"
feature over ajax, but when I try to add js to execute when the ajax
reponse completes, a ComponentEventException is thrown saying:
No object of type org.apache.tapestry5.RenderSupport is available from
the Environment. Available types are
org.apache.tapestry5.ValidationTracker,
org.apache.tapestry5.services.ComponentEventResultProcessor,
org.apache.tapestry5.services.FormSupport,
org.apache.tapestry5.services.Heartbeat. [at context:blog/View.tml, line
51, column 73]
I've verified in the TapestryModule#contributePartialMarkupRenderer
method, line 1647, that a service named "RenderSupport" is being being
added to the pipeline, which suggests that it should be available for
injection.
The page that's using (or want to use) it in an ajax response explicitly
checks request.isXHR(), and then adds script code via
renderSupport.addScript("");. Have I missed something?
Thanks in advance,
chris
