[gdal-dev] Can't create feature on layer for polygon

[Hugo Benicio]

Ok, I've discovered that myPolygon has geometryType *wkbGeometryCollection.*
When I try to:
    newDataSource->CreateLayer("test",NULL, *wkbGeometryCollection*, NULL);
it fails and returns NULL.

So my question now is: How do I create a wkbGeometryCollection layer (if
possible) or how do I correctly change the geometry type of my geometry
(from *wkbGeometryCollection *to *wkbPolygon*)?
*
*
Thanks in advance,
Hugo Benício.
