Update error while extracting a face in CAA

[22555]

Hi

While trying to extract a face in CAA, I get an update error. If updating is commented and Extract feature does not have face selected in CATIA.

Any help would be appreciated, Thanks

CATFace_var pFace(FacesList[facesIdx]);

const CATIGSMExtractSolidePropag Proptype = ExtractSolide_TangentPropag;
CATISpecObject_var spExtractspec(pFace);
CATISpecObject_var spExtract = spGsmFact->CreateExtractSolide(spExtractspec, Proptype);


CATIGSMProceduralView_var curobj = spExtract;
if (NULL_var != curobj) {
rc = curobj->InsertInProceduralView();
spExtract->Update();
}
