problems with SGT

HI,

I've downloaded SGT V2.0 in order to use it. There is no problem in viewing the JRealTimeDemo in a JFrame, but now, if I try to open the same demo in a JInternalFrame (and I need that !), that's doesn't work at all, and I have the following error message :  

java.lang.NullPointerException
 at gov.noaa.pmel.sgt.PaneProxy.draw(PaneProxy.java:115)
 at gov.noaa.pmel.sgt.PaneProxy.setBatch(PaneProxy.java:740)
 at gov.noaa.pmel.sgt.JPane.setBatch(JPane.java:578)
 at gov.noaa.pmel.sgt.demo.JRealTimeDemo.<init>(JRealTimeDemo.java:52)
 at gov.noaa.pmel.sgt.demo.JRealTimeDemo.main(JRealTimeDemo.java:56)

Looking in paneProxy, I've seen that the draw() method couldn't work because of the instruction :
Graphics g = pane_.getGraphics which gives null with a JInternalFrame, whereas she gives an object of type sun.awt.windows.WGraphics with a JFrame.

Can you help me, or explain me where my error comes from, or how to resolve it ?


Sincerly yours, 

Fabienne Lagarrue
