Re: [Wicket-user] Unknown Runtime Exception in Ajax?
Yes, I've tested some more and I only get this error in my Ajax debug window
under IE. In Firefox, it correctly loads the modal window.
However, in Firefox it fails a few steps later because it is unable to
locate a form element by ID, when clearly the form element is coming back as
part of the Ajax request, I can see it in the log.
Are there known issues with Ajax not being able to find elements by ID when
those elements only exist in markup that was updated by Ajax, and they
weren't in the original markup?
I'm trying to build a very Ajax-dependent UI that has multiple nested modal
windows and lots of ajax tabbed panels and so forth. Should I scale back my
optimism? Are there tricks/pitfalls I should be aware of?
Using 1.2.4.

Re: [Wicket-user] Unknown Runtime Exception in Ajax?
yeah, i'm not really doing anything custom for calling javascript or
anything.
this is all just standard ModalWindow show/hide behavior, and button onclick
events which launch new modal windows or update state of existing panels and
repaint.
i haven't written a single line of javascript or any special code to
generate javascript, just relying on all the standard ajax controls.

Re: [Wicket-user] Unknown Runtime Exception in Ajax?
At the risk of pointing out the obvious,
1) Make sure you're not including a component in your AjaxRequestTarget
that might be invisible (i.e. not in the DOM) when the response is received.
2) Double check that any component added to your AjaxRequestTarget has a
markup id.
I'm just now getting up to speed with Wicket and the only ajax problems
I've run into have been due to simple mistakes like the above or
problems on the Java side of things (although I haven't done anything
terribly advanced).
I'm anxious to hear if you can find the source of the problem...
