 This fixes a problem in the two tree and list controls that
   are trigger if the user app shows dialog in reaction to
   the user pressing e.g. <ENTER>. The edit text control will
   lose focus and emit another event. Might be possible to
   fix without adding another field, but this way it surely
   works.
  Also added correction to treecontrol as per listcontrol in
   the situation when a label change happens by losing the
   focus and the user cannot reject it, another event is emitted.
