There is no corresponding <strong>setter</strong> which means that all additions or deletions of list elements have to be made on the <strong>"live"</strong> list.</p> </blockquote> <p>As the quote says that there is no setter as when you use the getter method it insures that a new instance of the list is initialized if not present.</p> <p>And after that when you have to add or remove anything you will have to use </p> <pre><code>getElement3().add(Type); </code></pre> <p><strong>UPDATE</strong> : Difference in marshalling for <code>null</code> and empty list</p> <p>Example where list is <code>null</code></p> <pre><code>@XmlRootElement(name = "list-demo") public class ListDemo { @XmlElementWrapper(name = "list") @XmlElement(name = "list-item") private List&lt;String&gt; list; } </code></pre> <p>OUTPUT will be </p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt; &lt;list-demo/&gt; </code></pre> <p>Example where list is <strong>empty</strong></p> <pre><code>@XmlRootElement(name = "list-demo") public class ListDemo { @XmlElementWrapper(name = "list") @XmlElement(name = "list-item") private List&lt;String&gt; list = new ArrayList&lt;String&gt;(); } </code></pre> <p>OUTPUT will be:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt; &lt;list-demo&gt; &lt;list/&gt; &lt;/list-demo&gt; </code></pre>

    1. COI still don't get the idea why would JAXB care to **insures that a new instance of the list is initialized if not present**!!! why would it care, JAXB works exactly the same if a list value was `null` or an empty list. and preventing `NullPointerException`s here is out of JAXB scope IMO.

    2. COFor JAXB null and empty list is **different**. In the following way: If the list is `null` then you would not find that element in the `xml` generated, but if the list is of 0 size then there would be an xml element `<list/>` present in the xml. So they both are different.

    3. COif the `nillable` property is true in the `xsd` then it should not generate that `null` check. AFAIK.

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.
