Comment 4 Tomas Hurka 2001-01-23 09:35:59 UTC 
getSelectedItem method of javax.swing.JComboBox returns null when user holds
CTRL modifier. It is a strange behavior, probably bug in Swing. To correct this
bug explicit test for null was added to all getSelectedItem methods. Attachement
with proposed patch, which will also correct some depricated API, follows this
comment.
