update a zone from within a component
Hi List,
How can I update a zone on a page from within a component placed on that
page? I can successfully pass the zone's id to the enclosed component
but I can't return the zone's body in any of the components handler
methods. How can I get a handle on the zone?

Indeed, that would do the trick just nicely. I was thinking way too
complicated, thanks Igor.

I'm not sure I understand completely what you are trying to do but why don't
you publish an event inside the handler method of the component. This event
can be handled in the handler method of the containing page by returning the
zone's body.

That's not what I was asking for. Maybe I was a bit unclear. Triggering
the update itself is not the problem but returning the correct content
for updating the zone from the event handler method of the component.
The zone should update itself with it's own content and that's the
problem. Inside the component I don't have direct access to the Zone on
the page. Passing the Zone as a parameter to the component works but
calling getBody() on it returns nothing it seems. I now have to use
ComponentSource to locate the zone in the page and then I can return
it's body from the event handler mehtod. That works but is ugly.

In https://issues.apache.org/jira/browse/TAP5-569, Fernando Padilla posted
some very useful Javascript code that I've used successfully in a project.
