Listen Branch
The first branch in a Listen shape for which a condition is met (a delay is reached or a message is received) will run, and none of the other branches will run. The first shape within a Listen branch must be either a Delay shape or a Receive shape. You can place any other shape below the initial Receive or Delay shape. You can use an activation receive in a Listen branch, but if one branch contains an activation receive, then all branches must contain activation receives, and no time-out can be used. The activation receive must be the first action in each branch.
