It doesn't look like you are using ActionForms... or at least if you are, they are not being controlled by the
Struts framework because they are not specified in the ActionMapping. Since that is the case, I do not think you have an acceptable reason to chain Actions.
See, the benefit of Action Chaining to assist prepopulation is usually just a way to get around the fact that the Struts framework only allows one ActionForm in its control per ActionMapping. When navigating between two pages you often need two ActionForms - one for the page you are on and one for the page you are navigating to. And when you need two ActionForms in a single request (unless you create and save the forms to scope yourself, thus bypassing Struts' total control of ActionForms) you need two ActionMappings.
I anticipate that some developers will not share my views. Let the debates begin!
