I have a portlet using icefaces 1.7.2-SP2 and works fine. I have updated icefaces to 1.8-RC1 version by changing icefaces.jar, icefaces-comps.jar and icefaces-facelets.jar. And noy I'm getting this error:
Client side state saving is not supported with ICEfaces
That is correct. Currently, only server-side state saving is supported with ICEfaces so you need have the context parameter set to server. You can also leave it out entirely as JSF always defaults to server.
