When a Changed Concurrency Control Strategy Is Used There Must Not Be a Version Field For The Persistent Type
This error occurs when the domain model contains a persistent class that uses the Changed, None or All concurrency control and a concurrency member (version field) is specified at the same time.
To resolve this error, remove the concurrency member (version field):
- Select the persistent class in the Visual Designer.
- Press F4 to open the Properties pane.
Set the concurrency member to (AUTO).
