My previous post is not correct (excuse me)... because now i have
successfully called RequestUtils.createActionForm() with the cast needed:
Code was correct,
My error was the mapping name that must not end with .do.
Problem is that when i have prepopulated the ActionForm, saved it on the
request and return the ActionForward that forward to another Action class
(/prepareModify.do) the controller launch the new Action with the ActionForm
cleared (I think that try to populate it from the request).
There is a clear manner to pass information to an ActionForward that the
controller use to prepopulate ActionForms like request parameters?
