Hello,

first; thank you for an excellent library collection. I recently discovered
it, and I'm impressed!

My question:
How can I pass a pointer to an object into the state machine?

I want to use my state machine to control a real-life elevator. All the
functions for controlling this elevator is inside class Elevator;
I.e: myElevator->startEngine(UP);

I've tried different approaches as you might see in my attached code, but I
keep getting this error:
statemachine: ../boost/boost/cast.hpp:97: Target
boost::polymorphic_downcast(Source*) [with Target = ElevatorSM*, Source =
boost::statechart::state_machine<ElevatorSM, ElevatorActive>]: Assertion
`dynamic_cast<Target>(x) == x' failed.
Aborted
