I tried your suggestion, and only this did work.

struct OnlyIfNoDeferred
{
        template<class Event, class Fsm, class SourceState, class TargetState>
        bool operator()(Event const &, Fsm & aFsm, SourceState &, TargetState &)
        {
                size_t s_mq = aFsm.get_message_queue().size();
                size_t s_dq = aFsm.get_deferred_queue().size();
                return aFsm.get_message_queue().empty();
        }
};

s_mq = 1
s_dq = 0

This functor does now work. I just answer and ask again, because i thought
that the defered queue should be size=1 and not the message queue.... Is
this a bug or is this intended behaviour?
