FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
Given a JFileChooser with multiple file filters, the desired file filter is not selectable via it's first letter.

The JavaDoc for combo-box (JComboBox);

http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/doc-files/Key-Index.html#JComboBox

  states that items in the combo-box can be navigated to by typing the first letter of the item - the "Files of Type" combo-box does not honour this.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and run the supplied source code.
2. When the JFileChooser appears, click the drop-down for the "Files of Type" component.
3. Try to navigate to the file filter item "Project Files (*.prj)" by typing the letter "P" (or "p").
4. There is *no* navigation support as described in the JavaDoc for combo-box.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expected navigation to work, per JavaDoc.
ACTUAL -
No navigation to file filter items in the drop-down.

REPRODUCIBILITY :
This bug can be reproduced always.
