I noted also that there is an update for ICEfaces Project Integration plugin that doesn't work (ie. can't update because don't resolve some dependencies)
I had the same issue, Visual Web ICE Faces project hangs @ 75% on a 64 bit Window 7 machine. Was able to resolve by uninstalling Ice* and Visual icefaces plugins which was installed with netbeans 6.5.1. Downloaded the pulgins from icefaces.org for 6.5.1 net beans.
Sanjay,
Can you update without problems in the plugin manager? Or there is no way to update a manually installed plugin? (which it seems to be the case of Netbeans 6.8)
(As a side note, I have to say that I moved to Netbeans 6.8 + ICEFaces-1.8.2-Netbeans-6.7-modules -also manually installed-. I don't know to what extent this is reliable, but it's running smoothly up until now)
