FULL PRODUCT VERSION :
J2SE 1.4.2-b28
J2SE 1.5.0 beta

ADDITIONAL OS VERSION INFORMATION :
Win 2000

A DESCRIPTION OF THE PROBLEM :
Add editable JComboBoxes to a JTable.
Click on arrow button to display pop up for the combobox.
Click on arrow button again to hide the pop up.
Move to a different component in the UI.
The combo box is still displayed with the arrow button still visible.
It should have been removed on a focus lost event.
The combo box is correctly removed if you move to a different cell in the table
rather than a different widget in the application.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Please run the code below: -

1. Click on the drop-down combo-box(under column veggy)
2. Click in "set focus here" textfield.
