Hi Ben,
Can you please send us a complete test program that can
reproduce this problem ? This code given below is just a
BoxShape class.
I guess the mouse rotate behavior somehow select the
transform branch group to rotate which is above all the multiple
box shape branch groups. This is probably because when
public MouseRotate(TransformGroup transformGroup)
is created, the transformGroup pass in is not the one
localized to the individual BoxShape.
Thanks.
