    <p>I am using struts2-fullhibernatecore-plugin-2.2.2-GA in a demo strut2 project with Hibernate. I tried my best but can not make it work.

    1. COThis does not look related to Hibernate Validator. It looks like your Injection mechanism simply is not working. What are you using? CDI ? Check/debug your DI mechanism enable logging on that. Ensure it is bootstrapping and annotation processing covers scanning this class.

    3. COand if you use hibernate 3.6.10+ a NPE should be easy to check with a debugging breaking in CustomerDAOImpl what is the value of 'session' and 'transaction' you say it _IS_ injected but the NPE says otherwise. Split the statement into 2 'Query q = session.createQuery(...); return q.list();' which line is the NPE now ?

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).
