Hi Michael,
I try your test program, it throws exception at
java.lang.IllegalStateException: GeometryArray: must be in USE_NIO_BUFFER mode to
use this method

when trying to updateData()
That's why nothing is shown.It may because other GeometryArray pass in
is not construct using NIO_BUFFER. If I comment out the call I see
the model shown correctly on the screen (but not move since updateData
is comment out).
Please fix the application.
Thanks.
