Well, I suspect your major problem is that (unless you omitted some "global"
statement) the A_folder you bind to in manage_addFoo only exists during the
method call, and is thereafter lost and garbage collected. You might want to
think about making A_folder an attribute of the instance, which you would do
by altering the assignment to:

    self.A_folder = ...

You can then simply refer to it as self.A_folder in the other method.
