pymel: getPointAtUV error

Hi guys!
I'm trying to get the worldspace point of an uv coordinate with the getPointAtUV command.
Unfortunately I always get an error that I don't really understand.
Code:
msgGeo = polyCube()[0] faceIter = msgGeo.faces for f in faceIter: print f.getPointAtUV( (0.0, 0.3), space="world", uvSet="map1")


the error is always:
# Error: RuntimeError: file C:\buildforge\Maya_2011_Win32_Build\build\wrk\opti m\runTime\Python\Lib\site-packages\maya\OpenMaya.py line 6383: (kFailure): Object does not exist #

I know, there's already a similar thread regarding this issue, but it doesn't help me out..

Any ideas?

cheer, Seb

It fails because the uvs are outside the face.

You could do something like:
Code:
for f in faceIter: try: print f.getPointAtUV( (0.0, 0.3), space="world", uvSet="map1") except: print 'the uvs are not inside of '+f
