I'm not exactly sure of your sequence of events, but keep in mind:
- If your form bean has a validate() method, then by default the
ActionServlet will call that validate method. If it returns any error
messages then the ActionServlet forwards to the specified input. This
all happens BEFORE the call to your Action.perform method. So, if the
input page depends on the Action.perform putting certain beans into the
session, it might not happen.
If this is what's happening to you then I'd refactor the code:
- set validate="false" in the action tag,
- in Action.perform set up your session beans
- in Action.perform do your validation
- if there are any errors then forward to the input
