Macro execution
Hello together,

at this time I got headache from my problem so I thought its time to ask you.

Ive recorded a Macro in Java (a very simple one to create a geometry, mesh it and afterwards run a simulation).

I also used Netbeans to create a GUI with a "Simulation" Button. So as you know ive got two classes (both in the same package).

When the button is pressed the simulation shall start.

Class ONE: Macro code recorded from java with "execute0" for the methode to create geometry, mesh and run simulation.

Class TWO: GUI with "Simulation" Button.

I used in Class TWO:

ONE start = new ONE();



If I run the macro the GUI is shown correctly. BUT I always get a Nullpointerexception at

CadModel cadModel_0 =
simulation.get(SolidModelManager.class).createSoli dModel();

Can you please help me with this problem.

Thanks a lot in advance

Best regards,

Have you tried running your macro file with class ONE? Click the button "Play Macro" and select the file Does it work properly? Could you show all the jave-code of your class ONE declaration?
