The debugger suggests that in the create method the
getPrototype() call resturns NullFC. Why?
Cheers,

P.S.: I'm using the current cvs version....
//! create a new instance of the class
inline
AVCodecGrabForegroundPtr AVCodecGrabForegroundBase::create(void)
{
AVCodecGrabForegroundPtr fc;
if(getClassType().getPrototype() != OSG::NullFC)
{
fc = AVCodecGrabForegroundPtr::dcast(
getClassType().getPrototype()-> shallowCopy());
}
return fc;
}
