Wow... I did a search through all our projects for places where we
call performParentAction() and I found a whole bunch of component that
are catching and swallowing like this:
try {
String s = (String) valueForBinding("parentAction");
if (s != null) {
performParentAction(s);
}
} catch (Exception e) {
session.addUserMessagesFromException(e);
return null;
}
Bad huh? :-)
I'm changing all of these to extend the base class MPVWOComponent and
then I should know which is getting the exception and what it is!

You are right... Good idea... but it may be challenging as the
performParentAction() calls an action in a parent component and

Hey, I did not write those components hehehe... but it's clear to
me it is overly complex from the way I usually do things in
WebObjects. And it's one of legacy components which seems to be
screaming for re-design. :-)
Thanks for the suggestions.. I'll try them to find out WHERE and
WHY...
The deep call trace is why i suggest putting a try/catch in your
base component's performParentAction -- so all your components have
to pass through yours ... SOMEONE in that chain is going to throw
out -- it's required for this to fail. If it DOESN'T, then there's
something else going on.
Yep... working on this... I'm first making sure all the components
extend my base class MPVWOComponent (who is a subclass of
ERXComponent).
then I'll put the performParentAction() in MPVWOComponent to try to
catch the exception assuming it's happening.
Thanks
