Problem with JCanvas3D

[aze]

Hi everybody

I have a problem with the experimental Class JCanvas3D offered by the Java3d 1.5 Api. I choosed this class because i want to have an lightweight component ,that i can use with other Swing Components.

I draw the JCanvas3D on another Panel by the paintComponent method.But whenever i click on another area on this panel the content of the JCanvas3D diasppears and only returns when i move the mouse over it.

How can i force the content of JCanvas3D to be shown permanently ?
