Hi,

I have noticed a strange problem with event processing with msm. 
My events derive publicly from a base events struct like this:

struct BaseEvent { virtual ~BaseEvent() {} };
struct ConcreteEvent : public BaseEvent {};


I my FSM i have a transition defined for ConcreteEvent,

When I do this :

void foo(const BuddyEvent& event)
{
       fsm->process_event(event);    // event is of type ConcreteEvent
}

The fsm fires a no_transition , and I see a message saying no transition for ConcreteEvent in state X (state X has a valid transition for ConcreteEvent)

However this succeeds:
void foo(const BuddyEvent& event)
{
       fsm->process_event(ConcreteEvent(0);   
}

I am using boost-1.49 and the boost msm library that comes bundled with this.

So my question is, why is msm not able to generate a valid transition for a concrete event passed as a reference to its base tyoe.

Thanks!
