I don't need a post. I just need 2 URLs, one for each value in the combo box. As I said, in Javascript + Struts this would mean something like 10 lines of code. The flow would be: 1) I select value C from combo 2) I click the button 3) I end up on the C specific page (used to add a new entity of type C, in this case). So no post/page reload should happen between 1 and 2. I also would like to keep as simple as possible. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4047896#...
