Thanks for your fast reply!<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div bgcolor="#ffffff"><blockquote style="border-left:2px solid rgb(0,0,0);padding-left:5px;padding-right:0px;margin-left:5px;margin-right:0px">

  </div><div><font face="Arial">Yes it&#39;s something which has been requested a few 
  times, it will be done, but I didn&#39;t come to it yet. In the meantime you have 
  2 solutions:</font></div>
  <div><font face="Arial">- exit the submachine using an exit pseudo state, 
  it&#39;s UML conform and visible in your diagram.</font></div>
  <div><font face="Arial">- keep a pointer to the parent-est machine. Not 
  very beautiful but it&#39;ll work.</font></div></blockquote></div></blockquote><div>I&#39;ve already tryied the ugly pointer solution... and works.<br>I&#39;m gonna try the first one, also to try an exit pseudo state... i&#39;ve never used yet!<br>

  <div>&gt;And, although &quot;fsm&quot; is the submachine, why the no_transition function 
  is not executed (this last seems a bug to me...).</div>
  <div> </div>
  </div><div><font face="Arial">I don&#39;t think so. If the submachine doesn&#39;t 
  handle the event, the upper one could, so it gets a chance to do it, etc. 
  until the top-level fsm. If no fsm including the top-level fsm brings a 
  no_transition, then it&#39;s a bug.</font></div></blockquote></div></blockquote><div>Then... I think we&#39;ve found a bug?<br>I&#39;m attaching a version of your tutorial as a test case of this bug.<br><br>The bug can be reproduced by:<br>

- Creating a functor action (FA) that process an event (E)<br>- Creating an state machine (SM) and a submachine (SSM) <br>- SM and SSM should call FA in some place of their transition table<br>- E should not be present in the SSM (it can or not be in SM).<br>

<br>If the FA is called by the SM, everything works as expected:<br>- no_transitions if E is not in SM<br>- the correct transtion if E is in SM (E is not in SSM)<br><br>But if the FA is called bu the SSM, nothing happens:<br>

- no_transition is not called if E is not in SM<br>- transition is not executed is E is in SM<br>  - ok, I&#39;ve just checked when E is in an orthogonal region of SM...<br><br><br>Please, let me known if it is a real bug and if a patch is easy or not (may be I can help...?).<br>

I think that if we fix this bug, then the ugly pointer solution can be removed!<br>;-)<br><br><br>Thanks!<br><br><br>Albert<br><br>
