This error is reported if you expand a path in Test Designer and multiple Test Designer models are assigned to the test objects.
Error message
Multiple start events were found in assigned models.
Cause
An object definition that had an occurrence in a path in a Test Designer model was deleted from the database. By deleting the occurrence, this path has been broken down into partial paths. It is no longer possible to uniquely identify the start object because each partial path has its own start object.
Solution
Test Designer models thus changed cannot be restored.
Delete the entire path from Test Designer and create it again.
