In JComboBox, the FOCUS_GAINED event is not fired if the combobopx is editable. This happens if the focus is set by tabbing into the component with the keyboard and not when the mouse is used to set focus to the combobox. This happens on both Solaris and Win NT


Steps to reproduce the same,
1. Run the application for which the sample code is given below.
2. Set focus to the first dummy button
3. Press <TAB> - focus shifts to the next dummy button.
4. Press <TAB> - focus shifts to the Combobox - Observe in the output that the FOCUS_GAINED event which is supposed to be fired in not fired.
5. Press <TAB> 3 times. - Ths focus is now set to the second combo box which has setEditable --> false.
6. Now the FOCUS_GAINED event is fired.
