Multiple keystrokes selection for a JComboBox in JTable

Question

Has anyone used multiple keystrokes selection in a JComboBox inside JTable before? I can get it done outside JTable by using: http://javaalmanac.com/egs/javax.swing/combobox_CbMultiKey.html
Looks like JTable has all kinds of problems to support JComboBox.
Suggestions?
Thanks,
James

If I read you right, you want to use a multiple keystroke combo box as an editor in a JTable?
If you create the JComboBox as you would like it and then install it as an editor in the column(s) JTable the editor will work like the JComboBox
Example:
//- you would have that keyselection Manager class
// This key selection manager will handle selections based on multiple keys.
class MyKeySelectionManager implements JComboBox.KeySelectionManager {    ....    };
//- Create the JComboBox with the multiple keystroke ability
//- Create a read-only combobox
String[] items = {"Ant", "Ape", "Bat", "Boa", "Cat", "Cow"};
JComboBox cboBox = new JComboBox(items);
// Install the custom key selection manager
cboBox.setKeySelectionManager(new MyKeySelectionManager());
//- combo box editor for the JTable
DefaultCellEditor cboBoxCellEditor = new DefaultCellEditor(cboBox);
//- set the editor to the specified COlumn in the JTable - for example the first column (0)
tcm.getColumn(0).setCellEditor(cboBoxCellEditor); Finally, it may be necessary to to put a KeyPressed listener for the Tab key, and if you enter the column that has the JComboBox:
1) start the editting
table.editCellAt(row, col);2) get the editor component and cast it into a JComboBox (in this case)
Component comp = table.getEditorComponent();
JComboBox cboComp = (JComboBox) comp;3) give this compent the foucus to do its deed     
cboComp.requestFocus();Hope this helps!
