It's not obvious to me.  I didn't test your simple case because what
you posted is incomplete.  Have you now verified that it doesn't work?

As I said, the example is incomplete, so it's hard to tell what
assumptions you may be making.

You can learn a lot that way ;o)

And the more-experience were hoping to get an accurate picture of what
you're doing ;-)
