Another guess is that you are getting selection events from the combo box as the JTable initialises it for editing the cell valueLooks like just the opposite to me -- when the cell is selected for editing, the previously selected item in its (combobox) editor remains selected, which does not trigger a itemStateChanged event in 1.6.x as in some earlier version (not sure exactly when the behavior changed). That's why
when i swith from one combox box to another combo box the details of the previous sombo box is displayed.The solution might be for getTableCellEditorComponent to call the same code as called by itemStateChanged which should, of course, be in a method of its own.
But you're right, we're playing guessing games here.
@OP: I strongly suggest that you post a SSCCE, a short program that demonstrates your problem.
