I think I might know what is going on. It just hit me. When the page is first loaded, the dataTable is empty. I populate it after I select a category from the dropdown and click the ok button.
Now, how do I resolve that if that is truly the case?On 6/22/06, Gregg Bolinger < [EMAIL PROTECTED]> wrote:To add another piece to the puzzle, I placed a commandLink with a different ID and the same actionListener outside othe dataTable, and it triggers the actionListener method just fine.

I've stripped the page of everything except what is causing the problem and also stripped down the managed bean to just support the page.
The commandLinks arren't triggering the actionListener. I am hoping a fresh set of eyes will be able to clue me in to why. Hopefully it is something simple. Putting the managed bean in session scope allows everything to work. But when in request scope, it doesn't work.

I started using FacesTrace to see if I could see any useful information. And what I've discovered is that when processing the page that works I get the following key/value:
categoryAdminForm:_link_hidden_ -- categoryAdminForm:_idJsp15:1:_idJsp18
However, when I click the link on the page that doesn't work I get
categoryAdminForm:_link_hidden_ --
No value. Problem is, I have no clue what that tells me. Anyone?
Thanks.
