[xwiki-users] Groovy or Velocity code to read combo boxes and text boxes

Hello all, I'm sure this question has been asked before but I can't seem to find anything using the all mighty Google, so I thought I'd ask. I've created a tracking application (ticketing / workflow) using "App Within Minutes". What I'd like to do using either Groovy or Velocity is when a ticket is "closed" (by changing the value of a combo box) is to gather some details from the closed ticket that appears in a few controls on the page and post them to another page in the wiki when the user saves the page. The idea is to keep a running log of recently closed tickets. I've been looking for examples in three parts that I think I need help with: 1. How do I capture a "combo box" change event using Groovy or Velocity ? 2. How do I get values of text boxes and combo boxes from a page using Groovy or Velocity ? 3. How do I write to a different page in the Wiki using Groovy or Velocity? I'm obviously going to continue searching Google, but any pointers / help is greatly appreciated. Thanks in Advance, Jason Clemons
