Create Maven Web Project first as File -> New Project -> Maven -> Maven Web Application -> Finish (Noticed that this is JavaEE profile but no server selction in project wizard)

Add web framework. Right Click on project -> Properties -> Frameworks -> Add -> ICEfaces -> OK

Netbeans throw EXCEPTION:
Unexpected exception:
The serverInstanceId parameter cannot be null

This is an issue with netbeans maven web project as it does not provide server instance id. ICEfaces integration requires server instance to check server classes and adjust configurations.
