Several smallish fixes:

Browse source 
* Check for group-by option in parent's child relation in getElementName().
  This is necessary for embedded group nodes to operate as named objects.
* Use specialized get code in getChildElement() if child relation is group-by.
  This is necessary to get group nodes after the change above.
* Fix NullPointerException when name is null in setName()
* Use the groupname as node name and also set an explicit "name" property in
  getGroupbySubnode().
