I am assuming both lists are present on the same page! If so on the first list have a onChange javascript event which calls a function that submits the page. When the page is submitted you get the value the user selected on the first list. Use this value to populate the second list in the form, put the form back into whichever scope you had it and forward the Action control to the same page.

The results will be got from database in action class. The first list will be pre-populated, not the second. Here are my questions: do I need another action class taking care of selecting part? Once I select the item from the first list, I will get this item in action class, then get results, how can I send them back and populate the second list? Or There are other better and easier ways to achieve this? thanks, victor __________________________________ Do you Yahoo!? Yahoo!
