Hi. I'm new on Apache Isis and I am trying to create a simple CRUD application about a video store. I have the entity Movie and the entity Category. The entity Movie has an entity Category. So, I would like to know how to create a domain service to persist the entity Movie with a combo box or list to choose an already persisted Category. When I put the Category in the parameters of the method, the webapp renders no one component.
