Hello, I'm trying to implement a PseudoExitState in my boost meta state machine. This is the situation: http://i55.tinypic.com/2a83yar.png. Currently, when going from Transport to either Situation A or B, it throws an "no_transition" in the SubState for the "convertible event" needed by the PseudoExit state. (This is event6 in the example described below) According to the documentation (http://www.boost.org/doc/libs/1_46_1/libs/msm/doc/HTML/ch03s02.html#d0e930) and the corresponding example, there should be some kind of transition triggered by "event6" from SubState2 to Substate1 (see http://www.boost.org/doc/libs/1_46_1/libs/msm/doc/HTML/examples/DirectEntryT..., in the transition table for SubFsm2). I don't see an arrow in the state diagram between SubState2 and SubState1, nor can I figure out why I would want such a transition. In my SubState's transition table, I have defined the transition from Transport to PseudoExit1 and 2: g_row< Transport , Sensor , Exit1 , &SubFront::SDownstreamCheck >, g_row< Transport , Sensor , Exit2 , &SubFront::SDownstreamNoCheck > and in the TopState from PseudoExit1 and 2 to SituationA and B: _row< Sub::exit_pt< SubFront::Exit1 > , TransportDone , SituationA >, _row< Sub::exit_pt< SubFront::Exit2 > , TransportDone , SituationB >, So do i have to handle an "TransportDone" event in the SubState? And what are my Start and End states? I would appreciate your help :) Best Regards, Johan
