Swing: Preventing CellEditor from losing focus

Question

I have a table ( in which I make a table cell editor consisting of a text field and a button. Clicking the button brings up a pop up menu with a date picker. The idea is that the text field should be updated whenever a date is selected in the date picker.

Problem is, when interacting with the date picker, the focus of the cell editor is lost, and as a result, the table is removed from the editor as a cell editor listener (JTable.editingStopped()).

Since the listener is removed, calling fireProperyChange() in the cell editor when a new date is set have no effect and no updates are propagated to the table / text field.

Do you have any ideas on how I can achieve the behavior I want?

Thank you.

Here's the call stack after setting a date in the picker:

Read the Swing tutorial on How to Use Tables. There is an example that uses a Color Chooser as a popop editor. The concept should be the same for a Data Chooser.
