Hi Christophe, I have an addition question regarding the pseudo exit point. The following code adds a pseudo exit point to your CompositeTutorialWithEumlTable.cpp example: // Exit event struct exit_impl : msm::front::euml::euml_event<exit_impl>{}; exit_impl ev_exit; ... // Submachine struct _Playing : public msm::front::state_machine_def<_Playing > { ... // Pseudo exit state struct Exit_ : public msm::front::exit_pseudo_state<exit_impl> , public msm::front::euml::euml_state<Exit_> {}; static Exit_ Exit; ... BOOST_MSM_EUML_DECLARE_TRANSITION_TABLE(( Exit == Song1 + ev_exit ),transition_table ) }; I'm in doubt what should be stated in the main machine's transition table. The Stopped state is never reached when this line is used: Stopped == exit_pt_(Playing , _Playing::Exit) + ev_exit However, this entry works: Stopped == Playing + ev_exit Could you please clarify what should be actually entered. -- View this message in context: http://boost.2283326.n4.nabble.com/msm-EUML-submachine-without-macro-tp35985...
