Hi Jens,
      
      the transition node is also connected to its container node
      (possibly a StateMachine), which explains why deleting it would
      leave behind a dangling edge. To get an intact rule, you have to
      specify the container node and the connecting containment edge as
      preserved elements.
      
      Note to developers: We should show a warning in such cases, as
      deleting an element without deleting the containment edge will
      cause the same issues in most cases. Or are the any objections?
      
      Regards,
      Daniel

    Hello everyone,
      
      
      currently I try to delete a transition of a state machine with a
      given name.
      
      
      Henshin only applies the transformation as shown in the
      attachement if "check dangling" is deactived. Why?
      
      
      In my example, Transition4 only has two states it is connected to
      which are to be preserved.
      
      
      Kind regards,
      
      Jens
