I have created a workflow dashboard following the Sharepoint Designer demo. I did "Copy & Modify" from Tasks to add WorkflowName and WorkflowItemId. Using the data source of this, I created a dashboard. But, from time to time, the data source disappear, and it indicates that unable to display the web part. Then I recreate the dashboard by recreating the data source from the Tasks, basically repeating the same steps. I have done this at least a dozen times. I am sure it's something simple, but being a non-technical person and non-SP Designer person, I haven't been able to figure out why. Any help I can get on this would be greatly appreciated.
