I get the following error, which I can't figure out:
Exception occurred during event dispatching:

nch5.jpPolyCylEdgeTab.updateGeometry(jpPolyCylEdgeTab.java:268)
My code jpPolyCylEdgeTab.java:268 is
theSO.SNProperties.setChild(BG, theSO.whereIsCylinder);
where theSO is my basic class for all objects in my scene, SNProperties is a
Switch so I can turn the object on and off, BG is a newly create BranchGroup
and is not null, whereIsCylinder is an integer variable with the value 4.
I print out the number of children in the Switch
System.out.println("NumChildren: "+theSO.SNProperties.numChildren());
and it print 6.
So how come I get an array index out of bounds? 4 < 6 so 4 is not out of
bounds.
Anyone have any suggestions?
