Hi,
Well, it is an AJAX request. The X-Requested-With header is properly
set, isXHR() will return true. I'm executing it in Javascript, just a
normal call. It's supposed to return a form that I can then display in
any DIV that I want, and I don't want to use zones here. So I would
think I should add a method in my Page class, "getStuff" or something
like that. And I basically want to call that method, which returns a
Block, from Javascript and get the actual rendered HTML to put in any
DIV of my choice.
How?
Tom.

Hi Tom.
You can definitely return a block as the result of an AJAX request. If it's
not an AJAX request then you will get an error about not having a result
processor.
Make sure that the zone parameter is set on the link you are using to
initiate the zone update, and that javascript is turned on. You can check
the request for isXHR to make sure tapestry thinks you are doing an ajax
request.

Hello,
I want to do something that should be simple but appears to be complex.
I want to render a Block and return the result. The context is a website
in which I want to use Javascript to fill a<div>. I don't want to use a
zone for this. What I did was make a<t:block> in the .tml file. Now what
I
want to do is send an event to the page, and return the rendered block
using JSON. A bit like this:
@Inject
private Block theBlock;
Object onTheEvent() {
return theBlock;
}
I figured out that this doesn't work, because BlockImpl is not handled.
Okay, I have to return a StreamResponse. What I would like is:
@Inject
private final BlockRenderer renderer;
Object onTheEvent() {
return new TextStreamResponse("text/html", renderer.render(theBlock));
}
Obviously the BlockRenderer service does not exist, but I would want it to
exist. Or something similar.
Who can help me out?
Tom.
