This issue is actually more serious. After the change made to add project template, icefaces project cannot be added on an existing web, jsf, or other project.

The fix includes added capability of getting java src path from jave project, getting jsf config from existing project. etc.

From stackoverflow.
I am configuring a maven web app in Eclipse now. I use ICEFaces+Hibernate+Spring. When I was trying to add ICEFaces in project facets, the "Unhandled event loop exception" always prevent me to add IceFaces successfully. I attached the project facets and the exception stack trace.

Please help me solve it.Thanks a lot!
