Hi All I have run in to the following problem : if I have 3 state machines where 1st has a composite state which has one more composite state than the most inner one enters to a pseudo exit state which sends finish event. The middle one has a transaction from the most inner pseudo exit with even finish to a pseudo exit middle state which sends finish again. The most outer state machine has a transition from the middle pseudo exit with event finish to a internal state. when the most inner pseudo state sends event finish it ends in a NO transition on the most outer state machine instead of triggering the transition in the middle state machine. please find the sample code to reproduces the problem and execution output in attachment to . a part of the execution output : leaving: Stopped entering: Playing entering: Playing::PseudoEntry1 leaving: Playing::PseudoEntry1 entering: test1Sm::initial leaving: test1Sm::initial entering: test1Sm::TestPseudoExit1 no transition from state 1 on event struct `anonymous namespace'::finish Is it a bug or I'm doing something wrong ?.
