title: How to realize direct arrows with PlantUML?
body: <p>I am trying to create an activity diagram with PlantUML that does contain arrows that go back to existing nodes. </p>
  
  <p>What I am looking for is a diagram that includes the two arrows "Arrow 1" and "Arrow 2" in the picture below:
  <a href="https://i.stack.imgur.com/QsamW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QsamW.png" alt="plantuml diagram with the desired arrows"></a></p>
  
  <p>I have tried creating this using the <a href="https://plantuml.com/de/activity-diagram-beta" rel="nofollow noreferrer">PlantUML beta syntax for Activity diagrams</a>.</p>
  
  <p>I achieved the diagram below:</p>
  
  <p><a href="https://i.stack.imgur.com/2VBAx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2VBAx.png" alt="plantuml diagram without the desired arrows"></a></p>
  
  <p>by writing the following PlantUML code:</p>
  
  <pre><code>@startuml
  
  start
  
  :new - please check;
  
  while (check sucessful?) is (is an error)
    :to solve;
    :in progress;
    :solved;
  endwhile (not an error)
  
  :erledigt;
  note left
      reason:
       * done
       * not an error
       * not fixable
  end note
  stop
  
  @enduml
  </code></pre>
  
  <p>Does anybody has a hint on how to achieve this? It does not matter to me if the result is achieved by using the beta syntax or <a href="https://plantuml.com/de/activity-diagram-legacy" rel="nofollow noreferrer">the older syntax</a>.</p>
