Table rows get deselected

Question

Re: http://forums.sun.com/thread.jspa?threadID=5431255&tstart=0
I was not trying to hijack a thread. And I was not changing the subject. I just want to know what the solution to the OP's problem was. My problem is similar. There was only "probably" answers and "try" something else. What actually fixes the problem? If fireTableDataChanged is not the right thing to use because it deselects rows, what is there that updates the table but does NOT deselect rows?

Answer 1

1) store the selected rows
2) update the model
3) reset the selected rowSounds simple. But I notice the lack of plural in step 3. There doesn't seem to be a setSelectedRows() method that would take the int[] returned from getSelectedRows() and reselect those same rows.
Here's a solution I found to do the deed. Rather than use the fireTableDataChanged(), which clears the row selection and also the ListSelectionModel, use the fireTableRowsUpdated() method with the range retrieved from the ListSelectionModel, as follows:
    ListSelectionModel lsm = chanTable.getSelectionModel();
    AbstractTableModel model = (AbstractTableModel) chanTable.getModel();
    model.fireTableRowsUpdated(lsm.getMinSelectionIndex(), lsm.getMaxSelectionIndex());
