As no-one has provided any thoughts on this one I thought I would repost and
give a bit more detail on how the error is being caused.
Problem: The validate(mapping, request) method on the ActionForm class is
not completing sucessfully in Struts 1.0b3 where it was in Struts 1.0b1.
Detail: This is a form that has a couple of struts file upload controls on
it (as well as text fields etc) so I suppose that might be related somehow.
The exception being thrown in the log is :-
java.lang.ClassCastException:

Does anyone have any ideas? This one has got me totally stumped and without
a solution we will have to remain on Struts 1.0b1.
Thanks in advance,
Graeme.

Subject: Moving from Struts 1.0b1 to Struts 1.0b3
Currently having a problem with migrating code from using Struts 1.0b1 to
Struts 1.0b3
Everything seems to work fine apart from the fact that the validate methods
on our form beans (ie subclasses of org.apache.struts.action.ActionForm) no
longer get called successfully. I have had a look through the release notes
and cannot find any reasons why these methods would no longer work.
Any ideas people? The following error is what gets thrown in the tomcat
log.
