Can someone help me, if I use Thread, in order to
move the Figure from GEF , but unfortunately with me
always return errors, if I Thread with start() start
(wenn with run(), then no problem, but that is not Thread),
then following errors:

Exception in thread "Thread-5" java.lang.NullPointerException

here ist code this method, which I think, error:
protected void refreshVisuals() {

Rectangle bounds = new Rectangle(getCastedModel().getLocation(),
getCastedModel().getSize());
createFigureForModel();

if(getFigure()!=null && ((GraphicalEditPart) getParent())!=null
&& bounds !=null && this != null)
((GraphicalEditPart) getParent()).setLayoutConstraint(this,
getFigure(), bounds);

}
