Ok...I think I know what is going on, but can someone please tell me if this is correct or not. Action1 sets up the ActionForm and sets a number of variables in it, including the Vectors which are used to generate the drop down list boxes. The form is displayed to the user with the values which were populated in the form. The user submits the form, a new ActionForm is created and the variables in the fields the user filled in on the form they submitted are set in the new ActionForm. The values in this new ActionForm are then passed to the processing Action? The Vectors I populated in Action1 are not set in the new ActionForm because since the user does not set them in the form they submit.
Does this sound correct?
