Thank-you for your replies.
When adding a reference variable to the Playground database, the code that takes a string name has to query the WFA database for the database ID and put it in the database.
For example, a service dictionary definition contains a reference variable to a policy and a service name. When adding the service, the user input is the service name and the policy name, both strings. There seems to be no WFA code that converts the policy name string to the policy database ID that is needed for the reference variable. The code that adds a service instance needs to fetch the policy ID from the policy name in the WFA database and add it to the service instance.
