    1. COIt seems Hibernate expanded the signature on two methods, but otherwise this works fine for me. Ever considered contributing it to the Hibernate project?

    2. CO@raisercostin, I am trying what you have explained above. I am not sure what would be the parameter values in the annotation. Can you please elaborate on it or point to the source where I can get more information on it.

    3. CONow I understand. The parameters are like type: DealType where type is the key used EnumUserType and value is the class (use complete class name including package).

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
