Yes, it's been fixed and verified by QA team, then closed. Please post the information on how to reproduce the problem: page/bean code.
I apologize for the confusion. I am actually using t:columns.
I posted a .war file for review with the jira: RF-1668. https://jira.jboss.org/jira/browse/RF-1668
The toolTip IS NOT working with t:columns. Trying the fix using rich:dataTable with t:columns results in the table not being displayed.
I have confirmed the the toolTip IS working with the specified fix (rich:dataTable & t:column).
What are the thoughts on this?
PS: I modified the title of this post by adding t:columns for future reference.
