In the same code below, double click on any tree item, start typing:
"HELLO WORLD" using the shift key (not by toggling Caps Lock), when you get to the space key, the tree item looses focus and you loose your edited value.

I think the problem is from behavior classes of ListView/TableView/TreeView which are consuming the SHIFT+SPACE event before it reaches the text field.

Maybe when in edit mode (isEditing()), this keyEvent should not be consumed?
