Tag out of sync problem

    Hi :)

    I am sorry for asking something this simple, haven't done much scripting but I have a really simple script, that creates a NormalTag on the selected objects. It's working fine on primitives but not on real geometry.

    It crashes C4D if I execute the script on a 3D mesh with the error: Object "ObjectName" - Tag 5711 not in sync. Any hints on how to fix it and what I am doing wrong?

    Thank you in advance!

    def main() :
        doc.StartUndo()
        
        objs = doc.GetActiveObjects(1)
        
        if not objs:
            gui.MessageDialog('No objects selected.')
            return
        
        for i in objs:
            
            tag = i.MakeTag(c4d.Tnormal)
            doc.AddUndo(c4d.UNDOTYPE_NEW, tag)
            
        c4d.EventAdd()
        
        doc.EndUndo()
        
    if __name__=='__main__':
        main()

    normalTag are special variable tag since they need parameter for init (basicly the number of polygons)

    import c4d
      
    def main() :
        doc.StartUndo()
        objs = doc.GetActiveObjects(1)
        
        if not objs:
            c4d.gui.MessageDialog('No objects selected.')
            return
        
        for obj in objs:
            normalTag = op.GetTag(c4d.Tnormal)
            if normalTag:
                print 'tag already exist'
                continue
            
            #if there is no tag initg:
            poly_cout = obj.GetPolygonCount()
            normalTag = c4d.NormalTag(poly_cout)
            
            #Assign
            doc.AddUndo(c4d.UNDOTYPE_NEW, normalTag)
            obj.InsertTag(normalTag)
            
            
        c4d.EventAdd()
        
        doc.EndUndo()
        
    if __name__=='__main__':
        main()
      
    
    

    For manipulate data I suggest you to read the c++ sdk wich is way mroe relevant than the python one on this topic.
