i have a problem using the Web Service Call Action in one of my Workflows. Everytime the Workflow gets to this action while running i get the following error:
Object reference not set to an instance of an object.
If I use the same action in another Workflow it works. Even if I use the same settings, (URL, Method, XML-structure).
The WebService and the backend work just fine.
I've tried to...
* export and re-import the Workflow
* delete and re-create the Workflow
* remove and re-add the action
But nothing seem to work.
