Subject Re: [jira] Closed: (MYFACES-981) <t:dataList> action/action listener/model upate/ were not called
Date Sun, 15 Jan 2006 07:28:18 GMT
I tested <dataList> using the following simple example.
  testBean is session scope. The commandLink action method inside <dataList> was never
called.  I tried <inputText> with dataList before, model update method was never called.

   
  I am using nightly build 2005.11.20.  Any one has the same issue with dataList? Please let
me know if you use dataList successfully with inputText and commandLink.
   
  Thanks for help,
Dave

Resolution: Invalid

Dave,

This situation is almost never a bug, but instead a usage error.
The information you've posted strongly points to you failing to preserve your UIData model
between requests.

Make #{treeNode.children} session scoped, or use t:saveState to preserve it, and the problem
will probably be solved.

I recommend that you discuss this on the user list if you have further questions.
If it turns out to be a bug, we can reopen the issue with an example showing the bug.
