Sergei Rogovskiy commented on JBSEAM-342:
-----------------------------------------

I think there is an issue with SeamVariableResolver when AJAX bean tries to resolve variable at some point. In fact using standard variable resolver solves the problem.  I am getting a nullpointer which is pretty obviosly comes from Seam. Using standard variable resolver is not a workaround since it disables all seam features, so I think the issue is pretty big.
