    1. COMaybe. The user object is not a JPA managed object, it is JDBC managed. There are 2 places when the user object has the dealer object set to it. One is in the spring UserDetailsContextMapper, and the other is in a struts action. When the dealer logs in, their dealer object is set into the permissioned user so that it doesn't have to be retrieved, and so that it can be used to limit queries to just their data. When a system admin logs in, the sysadmin person selects a dealer to manage from a list, and I set the dealer object to the user so I can reuse artifacts. See Addl. code above

    2. COOk, so the LazyInitializationException only happens when the dealer object is set into the PermissionedUser object in the struts action, not when the dealer is set into the PermissionedUser in the UserDetailsContextMapper. So, this is starting to look like the right answer. Why would the object be detached in the struts object? Is it because my struts method is get* and that is a read-only transaction in the applicationContext.xml file?

    3. COOk, the problem is related somehow to transactions, so I guess I don't understand this as well as I wish I did. In my original code, the problem only showed up in the struts action. By using the struts Prepareable interceptor and the paramsPrepareParamsStack, I was retrieving the dealer in the prepare method, and setting the dealer to the user in a different method. When I moved the method call to set the dealer to the user object in the same transactional method, the LazyInitializationException disappears. Refactored working code posted above.

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.
