    <p>First, for any dependency set with @Autowired, you must declare a Spring Bean foreach DAO you will use, and it will be injected at runtime. </p> <p>Maybe these DAO need to have a sessionFactory reference like this:</p> <pre><code>&lt;!-- a dao in which you inject your Hibernate SessionFactory bean by its own id --&gt; &lt;bean id="userDAO" class="com.enterprise.model.dao.UserDAO"&gt; &lt;property name="sessionFactory"&gt; &lt;ref bean="sessionFactoryId" /&gt; &lt;/property&gt; &lt;/bean&gt; &lt;!-- activate the @Repository annotation --&gt; &lt;bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /&gt; </code></pre> <p>Secondly, maybe you forget to add this inside your Spring XML configuration:</p> <pre><code>&lt;!-- Add JPA support --&gt; &lt;bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"&gt; &lt;property name="loadTimeWeaver"&gt; &lt;bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/&gt; &lt;/property&gt; &lt;/bean&gt; &lt;!-- Add Transaction support --&gt; &lt;bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"&gt; &lt;property name="entityManagerFactory" ref="emf"/&gt; &lt;/bean&gt; </code></pre> <p>Third, your interceptor stuff: </p> <pre><code>&lt;bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"&gt; &lt;property name="interceptors"&gt; &lt;list&gt; &lt;ref bean="openEntityManagerInViewInterceptor"/&gt; &lt;/list&gt; &lt;/property&gt; &lt;/bean&gt; &lt;bean id="openEntityManagerInViewInterceptor" class="org.springframework.orm.jpa.support.OpenEntityManagerInViewInterceptor"&gt; &lt;property name="entityManagerFactory" ref="entityManagerFactory" /&gt; </code></pre>

    3. COAlso, how is the DAO not declared as a spring bean? It is annotated with `@Repository` and the `@Autowired` annotation is picking it up correctly. The `logger.info("Fetched DOI: " + myDOI.getDoiKey());` line in logDOI is being executed properly with the correct output.

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).
