I just put in an error message saying you are asking for something that
doesnt exist - I never really expected to see this scenario when I put in
this message. The arrayIndexOutofBounds happens if I dont catch htis case.
Let me put it this way: I am displaying values 1-10 in a page. I post an
action that changes the number of values to be displayed to 5 so a new bean
with just five values is manufactured and put in the session - in the
meanwhile the second click is forwarded by the actionservlet through the
requestUtils to the BeanUtil to look for the accessors and mutators for
values 1-10 but we have now have only 5 values in the bean so this is an
error condition.
The properties object sent to the BeanUtil seems to be sent from the old
form bean which had 10 values but the new form bean has only 5 values

It sounds like you are throwing an Exception of some
sort from you ActionForm? Is that right? The
ActionForm should just be a container to hold the
values from the form.
