You have to take that relationship on faith. Perhaps it's not the best example, but suffice it to say that I have many-to-many types of relationships in my data, and that the Forms are best segregated for re-use. It is highly inefficient for me to make a separate form for each combination of data relationship. Futhermore, there are many levels involved here. Distributions have Shipments, Shipments have Orders, Orders Have Items, Items have Tasks, Tasks have TaskDetails. Are you really suggesting I put all this in one Form? If I make a screen to query for TaskDetails which then uses the same jsp to display the results as the one that is linked to by the Task screen, then I must use this giant Form with mostly inconsequential fields, and add my TaskDetail query screen specifics to it, too.
If you have a generic query result page then you need to supply it with a generic result bean to display the data. Your TaskDetailQueryForm object is handled by your TaskDetailQueyAction which then puts your generic result bean in the request and forwards to the result page. I don't see why you would need action chaining here.

Where does it end? My other options are to make a new jsp, or make a jsp with some really nasty scriptlet in it to handle different forms. Right?
