thanks for the hint. I worked with a cvs snapshot of the 10.3.2002,
so your change slipped throuh. I've made the modification in the Redirect
but it didn't solve my problem.
I've investitgated the problem more accurate and found following:
A redirect from an action fails when we call addError() and after that we
throw an Exception which should be processed as explained in my previous
mail. If I remove the addError() method call the Exception will be processed
correctly and the Redirect is executed as desired. If we switch back to
ww1.2 everything runs fine. It seems that something changed when an
Exception is
thrown in an action/command after having called the addError() method.
I hope this helps to find the problem. Of course I'm more than glad to give
more info/help if needed to solve this problem.
Thanks for help.
Cheers
