Saving value from JComboBox in custom TreeCellEditor

I've got a JTree with a custom TreeModel and a custom TreeCellEditor displaying (for now) a JComboBox through the getTreeCellEditorComponent() override. The tree is displayed properly, with the nodes going into edit mode and displaying the JComboBox when I click on them.

Whenever I edit a node, changing the value from the dropdown, and then proceed to select another node from the three, I can see the TreeCellEditor's cancelCellEditing() being triggered.

What's the "correct" way to stop editing in stead of cancelling it, thus (hopefully?) making sure the model's valueForPathChanged() get's triggered?

After further investigation in the source code I found the answer inside the JTree class:

Setting JTree#setInvokesStopCellEditing(true) means editing is stopped in stead of cancelled whenever I change focus from one node to another. This also means my TreeModel#valueForPathChanged() gets called.
