stencil file save error!!

[YOUNGHEE]

I can change Master's custom property buy using Master.Open method.
But When I open document next time, Master's change is not saved.
So I add doc.save method. But it raised error.
I see the below message in the help file.

Message : Until a document has been saved, the Save method generates an
error.

How can I save Stencil file?
Please Help me.....
