Colin,
Yes, I forget to mentioned that I implemented your ideas but unfortunately the
MarkIterator is not rendered correctly. I slowed the timer period to update
every 15 seconds and modified my timer callback as follows:
/**Handles timer action */
public void actionPerformed (ActionEvent e){
synchronized (this.getTreeLock()){
//Remove all points.
m_Points.clear();
//Add the current position.
m_Points.add(new Point2D.Double(m_CurrLongDeg, m_CurrLatDeg));
//Update current position.
m_CurrLatDeg += 5.0;
if(m_CurrLatDeg > 90)
m_CurrLatDeg = 0.0;
m_CurrLongDeg += 0.0; //keep fixed, for now.
System.out.println("Update..................");
invalidate();
repaint((java.awt.geom.Rectangle2D) null);
}
}
I am currently in the process of building the GeoTools source code and
investigating this issue.

Does adding the synchronized block around invalidate() and repaint() or slowing
the update rate of the timer right down change anything? col
