> The Trinidad RowKeySetTreeImpl class can throw a NullPointerException if it is created with no CollectionModel.    For example, an NPE can occur if the set is iterated over while containing a null CollectionModel.  
> During state saving,  it is possible for  RowKeySetTreeImpl to temporarily contain a null CollectionModel before it is fully initialized by the component.    Also a user can create a RowKeySetTreeImpl instance in a backing bean and forget to initialize it with a CollectionModel.
> I will provide a patch for this.
