[Insight-users] SpatialObjects GetParent() problem

[Xabier Artaechevarria Artieda]

Hi Luis,

Thanks for your answer. I had:

SegmentSpatialObject::Pointer auxSegment2 = dynamic_cast<
            SegmentSpatialObject *> (auxSegment->GetParent());

instead of:

SegmentSpatialObject * auxSegment2 = dynamic_cast<
            SegmentSpatialObject *> (auxSegment->GetParent());

and that caused the runtime error.

Thanks for your help!
Xabier
