Visual Studio Workflow Error Occurred - Bitte um Hilfe

Ardenda erstellt 22 Okt. 2013 10:33

Hallo miteinander,

habe da einen großen State Maschine Worklow gebastelt. Nun bekomm ich (zwar selten) ein "Error occurred" .

Der Workflow startet beim erstellen. Hierbei handelt es sich um einen genehmigungsworkflow wo ich dann ein Statusfeld im Item update. Dabei bekomm ich ab und an folgende Fehlermeldung:

1. Meldung

2. Meldung

WinWF Internal Error, terminating workflow Id# d53a3934-9305-415a-b685-536b8b79adad

3 Meldung

Leider passiert das nur ab und an. Kann mir da einer weiterhelfen?

Hat das mit Update am Listitem zu tun? Kommen die sich da in die Quere? Hatte ein wenig schon gegoogelt aber noch nicht wirklich was gefunden, was mir weiterhelfen könnte
