      Description

      Swing-pre-1.0, jdk1.1.5, Solaris.

      When using a JComboBox as a JTable cell editor, keyboard navigation doesn't work properly. Alt+Down arrow doesn't post menu of the JComboBox.

      Steps to reproduce:
      1. Select the table (Note that on my system the table was
      not visible until I actually clicked on it. This may be another bug.)
      2. Use the arrow keys to select a cell in the first column
      3. Type a letter

      Note that the editor appears, but no changes can be made to the cell
      If the combo box arrow is selected with the mouse, then changes can be
      made with the keyboard.
