Hello everyone, I have an issue with* Boost MSM*. Using *Boost MSM eUML* I have created a state machine. Actually I created *HSM* (Hierarchical State Machine) or Composite State Machine as second name. And I faced with issue: How to share attributes between Parent State Machine and Sub-State Machines (or Child State Machine) ?? I have not found an answer on this question ... Could anyone possibly help me ? *Thanks,* *Best RegardsDenis Kotov*
