Bekannter Produktfehler CQ-49206.
Das Problem tritt beim Beenden eines Workflow-Dialog-Teilnehmerschritts auf, der nur Daten mit dem Workflow-Objekt und nicht mit der Payload speichert. Die POST-Operation versucht, die Daten mit der Payload zu speichern (und kann dabei scheitern). Das Sling Post Servlet bekommt keine ./ vorangestellte Felder, so dass versucht wird, die Werte wie cmd = advance in der Payload zu speichern.
