Edit node property causes deselection?

Oh well. It's working as expected.
The problematic line was

Code:
    @Override 
    public void resultChanged(LookupEvent le) { 
        refresh(true); 
    } 



In the child factory class.
It would refresh the nodes collection on any change, and a change was triggered by the property change. then the selected node would get deselected...
I am not sure why it was there. It was probably copied early on when working with a tutorial or something.
