Hi, I'm new in this forum...so if I wrong something about post, please tell me.

I'm using richFaces 4.0!

My problem is about rich:tab with inside some extendedDataTable. When I click on tab everything is rendered, but not the table header. Everything else works fine. With IE 8 works fine but not with FF! In FF all table header become visible after a page refresh (not necessarily generated by a button click but also if I open firebug).

any suggestions?

Regards!
