Re: javax.faces.FacesException: parent is null?

Posted by Catalin Kormos <ca...@yahoo.com>.

I've verified what you said, can't seem to be the
case. Now it works, but i did't do anything special,
just cleared some browser cache, rebuild my project,
restart server and that's it, it dissapeared as it
appeared out of nowhere. Interesting...i just hope not
to see that error again.

Thanks anyway for your interest.
