Unfortunately in my case the controller is not reused but the form bean is,
meaning if I was to do this validation in the controller I would have to do
it for every Action that uses this bean. Thanks for the suggestion but it
looks like I will have to stay on b1 until a more stable release of Struts
comes out (maybe the 1.0 final release?)
