JTable scrolling problem...

Question

I am having a problem with my JTable scrolling to show the newest added row. I have it working, but it jumps. Here is my problem.
I have the enter key acting like the tab key. I can force the scroll to the active cell but it jumps to row 0 for just a split second.
I know the problem is the way that I handle the Enter key. When I press enter I drop a cell down but then I force it back up.
Does any one know how to fix this? Here is some of the code that I am using...
if (event.getKeyChar() == '\n')
int r = tblDetailEntry.getSelectedRow();
int c = tblDetailEntry.getSelectedColumn();
if(r == 0)
r = curBill.billDetail.size();
c--;
if(r <= curBill.billDetail.size())
r--;
if(c == curBill.CODE)
c = 0;
if(r == curBill.billDetail.size() - 1)
detailEntry.addLine();     
r = curBill.billDetail.size() - 1;               
else
r++;
Rectangle rect = tblDetailEntry.getCellRect(r, 0, true);
tblDetailEntry.scrollRectToVisible(rect);
tblDetailEntry.editCellAt(r,c + 1);
tblDetailEntry.setRowSelectionInterval(r,r);
tblDetailEntry.setColumnSelectionInterval(c + 1,c + 1);     
}

My app is a bit more complex. It includes search criteria (Textboxes) and a
submit button which will write a dynamic SQL statment, execute and fill a table > thin an internal scrollpaneIt doesn't matter that you are using a "dynamic SQL statement". Whats important is how you build your TableModel and the TableModel you are using. I gave you an example that will use the DefaultTableModel and will work for a single row or 1,000 rows in the ResultSet.
Your question didn't state whether you are using the the DefaultTableModel or a custom TableModel. If you are using a custom TableModel, then chances are you have an error in you TableModel.
In no way am I asking for you or anyone else to supply me with code. Only a
possible step in the right direction. This is exactly what my example did. It proved to you that it works. So you look at your code and see what the differences are between one that works and one that doesn't. The example has three basic lines of code to build a scrollable table:
JTable table = new JTable(data, columnNames);
JScrollPane scrollPane = new JScrollPane( table );
getContentPane().add( scrollPane );
I don't know how is can get any simpler than that, so I would have no idea what to suggest you are doing wrong. Are you mixing AWT and Swing components?
