I was doing a 6.3 exercise of Rapid Crash course and stuck in creating overview pages of entities of the domain model. In the Domain model, for the entities in the blue color I am able to generate the overview pages but for the department and employee entities the generate overview pages are not allowed. Please suggest me how to resolve the issue.
As Per the Crash Course , Employee and Department are Non Persistent Entities – Means volatile tables ,not store in DB.
So for Non Persistent entity you cannot generate Overview Pages . Change the entity to Persistent and then try to generate.
