Right, the flow returns to the "input" page, which can be another action call. So I'm making my "input" point to "/myAction.do?method=myMethod", which calls a particular method of a DispatchAction.
It seems to work, but this kind of points to a larger question. Say I have some steps that need to be taken before displaying a form. For example, I might need to prepare the values in a drop-down menu. If the user submits the form and the Struts validation fails, it will re-display the form, so I'll need to run this prep method again. This means I'll need to point the input parameter to an action (or a method of a DispatchAction). As a result, for every form, I'm going to need two action-mappings defined in the struts-config file. One has validate="true", and its "input" points to the other action. That one has validate="false", and it simply prepares the form for display. Is this right? I would expect Struts to handle this a little more elegantly.
