T4.1: Custom exception page and async="true"

Hi,

I'm trying to "ajaxify" my app and I have problem with my custom exception
page.

If an unexcpected exception occurs my custom exception is executed.
Problem is that the client sees nothing of this (of course) since the ID
I've specified in the updateComponents does not exist in my custom exception
page.
I can see that the exception page is delivered in Firebug but nothing is (of
course) displayed to the user. (All I can get is a debug message like 'WARNING:
10:52:20: No ajax-response elements recieved.')

How should this be handled? I've read that it should work at least if I
don't use a custom exception page, but I've not tried this since I'd like a
little friendlier message to my users.

Cheers,
Malin

Thanks for your reply Jesse.

I have the following:
    <page name="Exception" specification-path="AppException.page"/>
in my .application-file to specify my exception page.
Don't know where I've learnt that (probably from this mailing list) but it
has worked fine without the ajax stuff.

I guess this is the problem (?). I'll try to use the
hivemodule.xml-tapestry.Infrastructure approach instead and hopefully it'll
work! Or else I'll get back to you ...

Peace :)
Malin

Maybe I've screwed up the exception page handling somehow ....Currently the
ajax response handler looks specifically for exception pages matching any of
the configurable exception page names via:

http://tapestry.apache.org/tapestry4.1/developmentguide/exceptionpages.html

Are you somehow using different names ?  If you have more specifics about
how you are contributing your custom exception page and possibly add it and
the issue to JIRA I can look in to it.

The infrastructure is in place and works well when the default exception
pages are rendered for notifying the client in a friendly "ajax way" when
exceptions happen.  (as in something similar to
http://opencomponentry.com:8080/tacos/ajax/ExceptionHandlerExample.html )
