Your react function looks fine. Do you by any chance directly or indirectly call state_machine::process_event from inside the state-machine (e.g. in- state reaction, transition, entry action, exit action, etc.)?
Thanks for the quick response. I only call process_event directly from outside the state machine. From inside, I do call transit() in a couple of reactions. That's how I understood guards were implemented. Maybe I missed something? Some of those transit() calls are to sibling states but most are to an uncle state (sibling to parent state). I never transit() to the same state. Here's an example: boost::statechart::result Inactive::react(const i_ready_command&) { if (state_downcast< const NotFaulted * >() != 0) { return transit<Active>(); } return discard_event(); } In few state's constructors, I call post_event(). -- dustin
