    1. COI think it might not be technically possible. I was trying to do somthing similar but I couldn't find anything useful or figure out the soultion, so I opted for having two Java attributes.

    2. COI agree with @Jubbat. It's frustrating, if technical restrictions of frameworks you use drive your domain model, but I didn't find a better solution in this case as well.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
