[WxPython] Which def is executed?

[merlem]

A Traceback? From where could I get that?
There is no error. Everything looks fine... except that in the case of the both shown defs, the one is exectued instead of the other.

I can add other menu items, they are okay. Only those both mix up.

Edit:
It'S the same without sid and rid. They were a 'remainder' of my attempts to find an access to the problem.
