Hi
I do not catch it:
<forward
name="validation_failed" action="RepopulateAction"/>
I do not think this synax is ok.
The problem is that i use autovalidation.
If validation fails i am forwarded to another action specified by input
attribute.Let's call it action2.
But action2 is never executed because before its execute() method is
invoked.Form bean is validated again.
Page attribute isn't changed so validation fails and i am forwarded to
another action ...
That's like this chain go.
If i turn off autovalidation i will follow your idea.

You could have the ActionForward mapped to an Action class in your
struts_config.xml file just as easily as a JSP, e.g. <forward
name="validation_failed" action="RepopulateAction"/> and then just
'return ActionForward("validation_failed")' if validation failed on
page1.
