title: Empty entry in ElementList SimpleXML
body: <p>my question is simple, but I can't find nothing about it.</p>
  
  <p>I Have a list class and an entry class for XML Serialization:</p>
  
  <pre><code>@Root(name = "entries")
  public class List {
  
      @ElementList(required = false, entry = "entry", inline = true, empty = true)
      private List&lt;Entry&gt; entries;
  }
  
  @Root
  public class Entry {
  
      @Element(name = "entry_id", required = true)
      private long id;
  
      @Element(name = "text", required = true)
      private String Text;
  }
  </code></pre>
  
  <p>I'm trying to parse this XML, which don't have any entries in the list:</p>
  
  <pre><code>&lt;entries&gt;
     &lt;entry /&gt;
  &lt;entries&gt;
  </code></pre>
  
  <p>The follow error is returned:</p>
  
  <pre><code>W/System.err(3335): org.simpleframework.xml.core.ValueRequiredException: Unable to satisfy @org.simpleframework.xml.Element(data=false, name=entry_id, required=true, type=void) on field 'id' private long com.android.apps.model.Entry.id for class com.android.apps.model.Entry at line 2
  </code></pre>
  
  <p>What am I doing wrong? The ElementList is set empty = true and required = false.
  anybody can help?</p>
