    <p>Almost everything is good, I see two little mistakes.</p> <p>First: </p> <p>You don't need <code>@Root (name = "entry/author")</code> just <code>@Root (name = "author")</code></p> <p>You should not depend of the parent of where it is going to be placed your class. </p> <hr> <p>Second One</p> <pre><code> @ElementList(inline = true, type = String.class, entry = "entry") private List&lt;Entry&gt; entries; </code></pre> <p>Should Be</p> <pre><code> @ElementList(inline = true, type = WhatsNewFeed_entry.class, entry = "entry") private List&lt;WhatsNewFeed_entry &gt; entries; </code></pre> <p>In fact I think you just need </p> <pre><code>@ElementList(inline = true, entry = "entry") private List&lt;WhatsNewFeed_entry &gt; entries; </code></pre> <p>because you are already specifying the collection name in <code>List&lt;WhatsNewFeed_entry &gt;</code></p> <p>The mistake is that you aren't specifying what class to Use, you was Specifying it as a String, that's why I asked what was "Entry" you wasn't telling the Serializer to use the </p> <pre><code>WhatsNewFeed_entry </code></pre> <p>After that, it should work for you</p> <hr> <p>As an additional oppinion, I don't really like the <code>@Root</code> because you are forcing the class to have an specific node name neither to force the properties or fields to be named as the XML expected tags , I think is a better approach to name it in the element, its more clear, you feel that you are making a real XML. And you design your classes as you</p> <p>I'm not very good with java, come from C# world but it's so similar.</p> <p>I would rewrite it a little like this:</p> <pre><code> //First level @Root (name = "feed") public class Feed { // All lines @Element("id") private String id; @Element("author") private Author_feed author; @Element("title") private String title; @Element("updated") private String updated; @ElementList(inline = true, entry = "entry") private List&lt;WhatsNewFeed_entry&gt; entries; } //Note that there is no root because it was already defined in the first level, //this way you can use the same class in differents node with different tag names, you //could even make an abstract class of author and in one just post the uri class isntead of // 2 author classes with the same properties public class Author_feed { // Lines 03-07 @Element("name") private String name; @Element("uri") private String uri; @Element("id") @Namespace(prefix = "y") private String id; } class Author_entry { // Lines 12-15 @Element("name") private String name; @Element("id") @Namespace(prefix = "y") private String id; } public class WhatsNewFeed_entry { // Lines 10-16 @Element (name = "id") private String id_entry; @Element("author") private Author_entry author; } </code></pre> <p>Hope it helps you to understand what was missing</p>

    1. COThat's very nice, thank you! Just one more question: how to fix the following error with "<y:agent/>" (not in this snippet) : Empty value for @org.simpleframework.xml.Element(data=false, name=, required=true, type=void) on field 'agent'

    2. COAs I said im not very good with java but I searched and I look at you mistake , that its because you are getting an empty agent, am i right? If that, you should place in @Element(name="agent", required=false), hope it helps

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.
