when i click on a column on which editor is attached , the getselectedrow return -1 ...... I have also tried list selection listener but nothinhg work properly....

i dont think it need code.... Please help.....

javax.swing.ListSelectionModel can returns MULTIPLE_INTERVAL_SELECTION, SINGLE_INTERVAL_SELECTION, and SINGLE_SELECTION. set that for JTable

I have set single selection interval............................. and tried it still return -1 again and again when i select column having combo bx in a row...

and how, I never have got problem with that, look here ...
