JCombo in JTable

Question

Hi all
I have looked at Steve and Franks Different Examples on this subject and have as yet not been able to implement right.
in some instances i have been able to get it to change in the database but not in the column ie does not render the value back
out problem is that the LOV databound drop down must display the name column but return the id coulum to the table
i have included the code below if you would like to take a look thanks
George
We are really gettin stuck now with this little issue. i mean i find it very strange that it is not documneted surely this is a regular requirment.

please help would really be appreciated

Answer 1

ok i have implemented steves example
the problem is that the combobox is returning type row that is the row that it bound via the vo bound to the LOV.
it should be returnin number.
so i can select the drop down but when i click on and option i get
