<Swing Dev> [9] Review request for 8072767 DefaultCellEditor for comboBox creates ActionEvent with wrong source object

[Alexander Scherbatiy]

Hello,

Could you review the fix:
   bug: https://bugs.openjdk.java.net/browse/JDK-8072767
   webrev: http://cr.openjdk.java.net/~alexsch/8072767/webrev.00

   This is a regression from the fix 8019180 Use JComboBox as it's own 
ActionListener leads to unexpected behaviour

   JComboBox has unexpected behaviour if it is used as it's own 
ActionListener: the selected value is empty and
   the drop down popup is closed after each up/down key event.

   The original fix filters action events which source does not equal 
JComboBox editor or editor component.
   However, in case of the JTable the event source is DefaultCellEditor 
which is different from the JComboBox editors.

   The suggested solution is to revert the fix for the issue 8019180 
back and fix the JComboBox unexpected behaviour.
    - Update the editor value  for the new selected item.
    -  "JComboBox.isTableCellEditor"  UIManager property can be used in 
a user application to avoid action events firing
   on each key navigation.


Thanks,
Alexandr.
