DataProvider in XML

My xml code looks like that.

The problem is, that the getUserDefinedProperty Mehtod is only called for someItems and not for title?

Do i do anything wrong with that xml?

<text>@title</text>
 
   <list>
  <_renderer><![CDATA[
  <listitem>
    <_onAction>${itemAction}</_onAction>
      <Text>@{item}</Text>
  </listitem>
  ]]></_renderer>
  <_items>@{someItems}</_items>
 
  </list>

Best regards

Patrick
