I am using boost::statechart. Instead of simple_state , using boost::
statechart::state.
Now i am able to access the state_machine member variable. but when i am
using custom::reaction or mpl::list it throught error.
Code Snippet:
struct NotReady : StateBase< NotReady, TopState >
{
  //typedef NotReadyStateList reactions;
  NotReady (my_context ctx) : my_base( ctx ){
  outermost_context().maxPairedDevices = 3;
  cout << outermost_context().maxPairedDevices << endl;
  }
template< class MostDerived >
  sc::result react( const PairingBaseEvents< MostDerived > & );
public:
  typedef sc::custom_reaction< StartEvent > reactions;
};
Error:
ndefined reference to `boost::statechart::detail::safe_reaction_result
NotReady::react<StartEvent>(PairingBaseEvents<StartEvent> const&)'
As it seems your compiler cannot match your react() signature against an  
expected one. Without complete compiling example it is hard to predict why.
