Hi, first off thank you to anyone for your response.
Here's my scenario. I have dynamically generate forms which create a list of items which allow you to click a vote button next to them. The amount of times the vote button has been clicked is displayed next to them and is updated by using an AHAH call. This all works extremely well and I was really surprised how easy it was to implement.
However the real problem arises with the more button on the bottom of the form. I have it set so that by default only 5 items on the form are shown for voting, a more button on the bottom of the form expands the form showing all of the items that are available for voting, this also uses an AHAH call. Now here is the problem. After I click the more button, if I click on the vote button for any of the items reveled it will simply do a page refresh and not run the AHAH call at all. I think this has something to do with the $form_state and page cache, but I really am not sure. I got the code that I'm currently using for most of the AHAH call back from the poll module.
I've pasted some of the code from the module below, I know it's sloppy and I'm sure that I'm doing the AHAH thing wrong since this is my first go at it. But any suggestions or recommendations would be greatly appreciated.
