I think that it is similar to the issue. Please consider it to see the workaround.
The workaround should be to include the toolTip id to render attribute of a4j:ajax (r:ajax if you are using RF5).
Have you been successful ?
The workaround does not work for me. I am getting stuck into issues after issues. Now I am trying a different approach by putting a4j:status around my datatable. I have a onstart function but this functions is invoked only 1 time. After first ajax call, onstart is not called again .
Does anyone know why onstart is called only once?
Issue Resolved!!! i cannot believe something so small can cause so many issues. basically I observed that even the smallest JS calls like oncomplete="alert(''hi)" were not working on my page. Also sorting, pagination was causing JS to not bee invoked, the behavior was little odd. a4j:status was working only once before you sort or paginate. Tooltip was not working inside datatable after sorting or paginating.
All these issues are resolved after I replaced <h:commandbutton> with <a4j:commandbutton> throughout the page. it is strange but works for me .
