title: TYPO3 extbase fluid: nested object in loop
body: <p>I have in a Object (dailysale) multiple nested elements (cashpoints) which contain again nested elements</p>
  
  <p><strong>dailysale -> cashpoints -> sales</strong></p>
  
  <pre><code>      -&gt; diffkinds -&gt; sales
  </code></pre>
  
  <p>...</p>
  
  <p>(where "cashpoint" holds the name and "sales" holds the actual in and out, 
  diffkinds holds some additional which have sales too )
  now I want to create a input/edit-form 
  In the partial to edit the dailysafe I've a loop:</p>
  
  <p></p>
  
  <pre><code>    {cashpoint.uid}&lt;br&gt;
      &lt;f:form.textfield property="cashpoints.{cashpoint.uid}.was" value="{cashpoint.name}" /&gt;&lt;br /&gt;
      &lt;f:form.hidden property="cashpoints.{cashpoint.uid}.__identity" value="{cashpoint.uid}"/&gt;
  
      &lt;f:form.textfield property="cashpoints.{cashpoint.uid}.einnahme" value="{dailysale.cashpoints[cashpoint.uid][einnahme]}" /&gt;&lt;br /&gt;
      &lt;f:debug title="cashpointdebug1"&gt;{cashpoint}&lt;/f:debug&gt;
      &lt;f:debug title="cashpointdebug2"&gt;{tagesumsatz.cashpoints[cashpoint.uid]}&lt;/f:debug&gt;
  
      &lt;f:form.textfield property="cashpoints.{cashpoint.uid}.ausgabe" value="{cashpoint.ausgabe}"/&gt;&lt;br /&gt;
  </code></pre>
  
  <p></p>
  
  <p>updating the name of the different cashpoints works, but I don'nt get any access to the nested sales.
  cashpointdebug1 gives me the actual cashpoint and as nested the sale,
  but if I want to access cashpoint.sales or cashpoint.sales.input (a property) I get null.</p>
  
  <p>What did I miss to access the nested object sales in the loop?</p>
