Hi,
looking at JMESwingTest, I wanted replace a SimpleCanvasImpl extended object of a JMECanvas by another one while resizing:
protected void doResize() {
impl=new MyImplementor(comp.getWidth(),comp.getHeight());
((JMECanvas)comp).setImplementor(impl);
}
This code worked with JME 1.x. But with 2.0, I got the following exception:
Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException

Best,

and I just did it as you described. But, I would prefer beeig able to replace it, not only for this cause. There seems to be a thread that I don't know how to access or stop.
