Rodney, I had similar problems with a DispatchAction. The problem is, when the validation fails, it does not come into your action class; the good news is that you can define an 'input' attribute in your actionmapping (struts-config.xml) which will be used when your validation fails; I had put a reference to a .jsp page, but you can also specify an action.
In my DispatchAction class, I have a method name validateError(...); you then define the input attribute as input="myAction.do?method=validateError" myAction is an action mapping which maps to the same class. in this method you then can initialize what you need.
