    <p>Thank you for the extra details, it wasn't immediately obvious what you were trying to do.</p> <p>The <code>@Qualifier</code> annotation is not meant to be used in the same way as <code>@Resource</code>. When you specify the meta-data <code>&lt;qualifier&gt;</code> element, you are overwriting the identifier that would be used when resolving <code>@Qualifier</code>. In this case, the <code>&lt;qualifier&gt;</code> identifier <code>"secondaryFoo"</code> replaces the <code>&lt;bean&gt;</code> identifier <code>"anotherFoo"</code>. If you changed your declaration to</p> <pre><code>@Autowired @Qualifier(value = "secondaryFoo") private Foo foo; </code></pre> <p>It would be autowired correctly. However, you can still use </p> <pre><code>Foo anotherFoo = (Foo) applicationContext.getBean("anotherFoo"); </code></pre> <p>to get the <code>&lt;bean&gt;</code> with <code>id</code> <code>"anotherFoo"</code>. Although this would fail</p> <pre><code>Foo anotherFoo = (Foo) applicationContext.getBean("secondaryFoo"); </code></pre> <p>If you are looking for how to autowire based on a unique id, you should use <code>@Resource</code>. The <a href="http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/beans.html#beans-autowired-annotation-qualifiers" rel="nofollow">documentation</a> states:</p> <blockquote> <p>If you intend to express annotation-driven injection by name, do not primarily use @Autowired, even if is technically capable of referring to a bean name through @Qualifier values. Instead, use the JSR-250 @Resource annotation, which is semantically defined to identify a specific target component by its unique name, with the declared type being irrelevant for the matching process.</p> </blockquote>

    3. CO@blue but that is expected, see the comments in your code. You have two beans of type Foo so the context doesn't know which one to give you

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).
