[Andinet Enquobahrie]

Hi Torleif,

Thank you for testing the newly refactored view classes.

This is definitely a bug. As you have pointed out, type defs were 
missing. Furthermore,  modification was needed in the input
argument types of the RequestSetView method to be able to handle 
ViewNew2D and ViewNew3D. I have committed  a fix to
the Sandbox.

Please update your check out and give it a try.

Let me know if you encounter other issues.

Thanks!
