Brutally Simple

Getting the job done in as easy and simple a manner as possible.

Sharepoint Designer Workflow: An item with the same key has already been added.

That’s the annoying message I got after activating the workflow feature and then trying to edit the workflow in SharePoint Designer.

The exact steps were as follows:

  1. Create a Reusable SharePoint Designer Workflow.
  2. Save it to the Site Assets library.
  3. Install it to the farm as a Farm Solution.
  4. Change your mind over lunch.
  5. Delete the web application you designed the workflow in.
  6. Recreate the web application, site and web.
  7. Install the solution to the site as a User Solution.
  8. Activate the feature in the web.
  9. Open the solution in Sharepoint Designer.
  10. Suffer the error.

SharePoint 2010 FetchlegalWorkflowActions SOAP exception:  System.ArgumentException: An item with the same key has already been  added.

To resolve this just undeploy and remove the Farm solution!  See this post for someone else who discovered this:
