[Bf-python] Add UV coordinates by python: is possible?

[Manuel Bastioni]

I've used this:

f.uv[i] = tuple(map(float, uvVertCoo))

it work, and the object, in
face mode, have all points in correct UV position.
Only...the point is not connetted: in the image window I can see only 
the points and not
the edge. The result in rendering is a sort of vertex colour based on  
texture...

I don't understand why...

thx,

             Manuel
