Can't scroll to last row in a JTable

Question

I am having great difficulty in getting a scrollable
JTable to scroll to the very last row.
I've done the following:
int lastRowIndex = table.getRowCount() - 1;
Rectagle rect = table.getCellRect(lastRowIndex);
table.scrollRectToVisible(rect, 0, true));
BUT, it always scrolls the the row just prior to
the last... never the last. I've checked, and my
lastRowIndex is correct. I've even tried something
as stupid as just increasing lastRowIndex by 1,
and it still does not work.
So, I am at a loss as to why this does not work.

Answer 1

Moving the scroll bar to the bottom (maximum) had
no effect. In fact, doing that alone ought to
acheive the same goal.
However, I have discovered that if I do either
(move scroll bar or set viewport to last cell's
rectangle) TWICE, it works.
I speculate that there is some kind of latency
in the GUI "knowing" what the maximum extent really
is. Trying to move to the end the first time fails,
but it does cause the GUI to refresh itself
immediately afterwards so that if I try this a
second time, it works.
I can achieve the same results if I simply
***force a re-paint before attempting to move
the the last cell***. Then, it works.
So, my solution was to do the following:
__ int lastRowIndex = myTable.getRowCount() - 1;
__ if (lastRowIndex > -1)
_____ // repaint the window first.
_____ Rectangle bounds = getBounds();
_____ bounds.x = 0;
_____ bounds.y = 0;
_____ paintImmediately(bounds);
_____ // Now, move to the last row
_____ bounds = myTable.getCellRect(lastRowIndex, 0, true);
_____ myTable.getScrollPane().getViewport(
_____ ).scrollRectToVisible(bounds);
