The argument passed to on_entry is not extended_back_machine because MSM does not know about it. You can either:

- implement test() within the fsm_ front-end
- provide a virtual, empty implemented test() within the front end and let the compiler find out itself about the overriden one: virtual void test(){}

HTH,
