Hi Ranjana,
I have tested for this issue here and both the MultiColumnComboBoxes with a common datasource seem to be working fine. Please refer to the
test sample attached and let me know if I have understood your problem correctly. If not, kindly modify the sample to show the problem and send it back to us. Also, in future address all your queries through Direct-Trac as far as possible. We appreciate your cooperation.
