Is there some difference in the way SaveAsClass treats properties depending on their origin?


YES. By design ? I think not.

With ADDPROPERTY() you have the same result,
SaveAsClass ignore these properties.

oBS=NewObject("Custom")
oBS.Addproperty("cSomeNewProperty","")
Addproperty(m.oBS,"cSomeNewProperty2","") && SaveAsClass ignore cSomeNewProperty2
oBS.SaveAsClass('\cSomeLib','savedclass')
