Failed to create assignment association

Feb 2, 2008 at 2:02 AM
After created the project association, I want to create assignment association, in the connector administration site, I click the "Create new assignment association" button, an error page appeared, which said "This operation could not be successfully performed. Please contact the administrator and refer to HandlingInstanceID: d544cd42-e1d9-42ab-a372-e6b5d3809da3 ", I go to eventviewer to lookup the error details, like following as:

Somewhere you have an invalid integer respresetning one of the fields for either your assignment or your work item. When the connector is trying to create the assignment association, it is trying to cast a string to a number; however, your respresentation of that number is invalid. Can you check the assignments that you have available to determine if there is something like this occurring?
