Thank you for your quick respond. I'm sorry for the small errors in my code, below is a code that compiles, but as I try to run ./statemachine I get the following error: Starting Elevator Entering Elevator Idle At Floor state Exiting Elevator Idle At Floor state statemachine: ../boost/boost/cast.hpp:97: Target boost::polymorphic_downcast(Source*) [with Target = ElevatorSM*, Source = boost::statechart::state_machine]: Assertion `dynamic_cast<Target>(x) == x' failed. Aborted So it is unable to run the test123() from the elevator class.

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]: Assertion `dynamic_cast<Target>(x) == x' failed. Aborted

Your code compiles well (after a few cosmetic changes, like fixing test123() name, adding "e" member to your fsm, etc.). boost 1.45, MSVC10. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

Thank you again. Now I got it working, but I'm a bit confused regarding the error. I can not see that I was in the destructor of the FSM, just the active state. But it is working. If anybody is interested, here is the working code: http://codepad.org/2LLfnFBT http://codepad.org/ALZmBUjJ Thank you very much for the help, Bernt-Johan 2011/3/15 Igor R

Thank you for your quick respond. I'm sorry for the small errors in my code, below is a code that compiles, but as I try to run ./statemachine I get the following error:

Probably this crash is related to the fact that you're already in FSM destructor, so dynamic_cast fails to cast to the FSM. It's worth seeing what standard says about dynamic_cast applicability in such a case... _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
