Hi Sven,
I see this very *deep* in the stack trace:
Caused by: java.lang.NullPointerException
at
org.apache.myfaces.trinidad.model.ChildPropertyTreeModel._getModel(Child
PropertyTreeModel.java:362)
at
org.apache.myfaces.trinidad.model.ChildPropertyTreeModel.getRowCount(Chi
ldPropertyTreeModel.java:196)
at
org.apache.myfaces.trinidad.model.BaseMenuModel.getRowCount(BaseMenuMode
l.java:70)
I wonder if you have a (reproducible) test-case for that ?
