I tried specifying the annotation for SF "containment". It did not work.

Where in the debugger can I check whether this spec is having an effect on
the behaviour of code generation?

So I would ask this: In general, given a bean, is there a way I
can directly generate a local var and init it with a new class instance
creation and make that local var a member of the getter method of the
container?

Thanks and regards,

Janak
