Previously in version 5.6.2 this:  
self.SegmentID = Segmentation.GetSegmentIdBySegmentName(segment\_name)  
retrieved the segmentID

In version 5.8.2, it returns none.  
Is that normal? What is the new equivalent for getting the segment ID in v 5.8.1?  
Thanks!

In fact, I think it is unrelated finally. In v 5.8.1, segment name is not by default the name as the segment ID in v 5.6.2 as I understand! thanks
