    <p>I have been debugging for many, many hours but I can't understand why the code is not working. Two service classes, annotated in the same way, show a different interceptor behaviour.</p> <p>Stack trace #1:</p> <pre><code>Daemon Thread [http-thread-pool-8080(1)] (Suspended (breakpoint at line

<p>It seems as if the interceptor is not invoked for the message service class. However, it does work for the user service class. Why could this be?</p> <p>The message service class:</p> <pre><code>@Stateless @Interceptors(GuiceInterceptor.class) public class MessageService { /** * The gmail folder default. */ private static final String GMAIL_ALL_MAIL = "[Gmail]/All Mail"; /** * The IMAP store cache. */ @Inject private IMAPStoreCache imapStoreCache; /** * The EJB resolver. */ @Inject private EJBResolver ejbResolver; </code></pre> <p>The user service class:</p> <pre><code>@Stateless @Interceptors(GuiceInterceptor.class) public class UserService { /** * The entity manager. */ @PersistenceContext(unitName = "hupa") private EntityManager em; /** * The session provider. */ @Inject private Provider&lt;HttpSession&gt; sessionProvider; </code></pre> <p>And finally the interceptor:</p> <pre><code>public class GuiceInterceptor { @EJB private GuiceInjectorHolder injectorHolder; @AroundInvoke @AroundTimeout public Object injectByGuice(InvocationContext invocationContext) throws Exception { Injector injector = injectorHolder.getInjector(); injector.injectMembers(invocationContext.getTarget()); return invocationContext.proceed(); } } </code></pre> <p>Hope there are experts on this, I am frustrated ;)</p>

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).
