JXTable convertRowIndexToModel wrong result after sort?

I have a JXTable in which a model is a List of distinct objects. There is a problem when I try to map the view index to model index after sorting the view by the selected column header. Using this code,

int[] selecteds = getTableMember().getSelectedRows();
if (selecteds != null && selecteds.length > 0) {
    for (int row : selecteds) {
        int rr = getTableMember().convertRowIndexToModel(row);
            System.out.println(row+":"+rr);
    }
}

I get this result:

11:240
12:328
13:1174
14:328
15:1174

I cannot understand why different view indexes map to the same model index?

Solved problem: I called fireTableRowsUpdated right after modify per row so the selected index is not correct anymore.

Verify that the objects in the List are in fact distinct. In particular, the Comparator used by DefaultRowSorter must be implemented correctly. Note that the default relies on the toString() method of the underlying objects, but you can specify your own implementation.
