A DESCRIPTION OF THE PROBLEM :
I have used TableRowSorter class for a jtable. After sorting jtable model is not getting updated. View gets updated ( sorting is working) but the backend value is returning the old values.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I will provide the code.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
using jtable not the jtable model
System.out.println(jTable1.getValueAt(selectedRow, 0));

SUPPORT :
YES
