title: How to Get Value from the OData Expand Binding
body: <p>I have a List with a binding. In this List, I return bank accounts and over the expand, I get the mandates for each account (1:n).</p>
  
  <pre><code>&lt;List id="bankAccountList"
      itemPress="onListItemSelect"
      items="{
          path: 'BankvbSet',
          parameters: {
              expand: 'MandatSet'
          }
      }"
      noDataText="{i18n&gt;msgNoBankAccount}"
      delete="onEndBankAccount"
  &gt;
  </code></pre>
  
  <p>Now I will check if there are any mandates with an appropriate status. So I have written a formatter for this and in that formatter, I get the data from the <code>$expand</code>. But I only get an array with the path of the mandates. Is there a way to get the complete data?</p>
  
  <p>Here is a piece of my current code:</p>
  
  <pre><code>&lt;List id="bankAccountList"
      itemPress="onListItemSelect"
      items="{
          path: 'BankvbSet',
          parameters: {
              expand: 'MandatSet'
          }
      }"
      noDataText="{i18n&gt;msgNoBankAccount}"
      delete="onEndBankAccount"
  &gt;
      &lt;items&gt;
          &lt;ObjectListItem id="template" 
              custom:bankId="{Bankdetailid}"
              type="Navigation"
              intro="{i18n&gt;labelBankId}: {Bankdetailid}"
              title="{Iban}"
              number="{
                  path: 'ValidEntry',
                  formatter: '.formatter.setBankAccountStateText'
              }"
              numberState="{
                  path: 'ValidEntry',
                  formatter: '.formatter.setBankAccountState'
              }"
          &gt;
              &lt;attributes&gt;
                  &lt;ObjectAttribute
                      title="{i18n&gt;labelBankName}"
                      text="{Bankdesc}"
                  /&gt;
                  &lt;ObjectAttribute
                      text="{
                          path: 'MandatSet',
                          formatter: '.formatter.setLabelMandateVorhanden'
                      }"
                  /&gt;
              &lt;/attributes&gt;
          &lt;/ObjectListItem&gt;
      &lt;/items&gt;
  &lt;/List&gt;
  </code></pre>
  
  <p>And in the formatter I get only the path as array</p>
  
  <pre><code>[
      "MandatSet(Application='1',SepaCreditorId='DE98ZZZ0999',SepaMandateId='5001549101000001',Status='4')",
      "MandatSet(Application='1',SepaCreditorId='DE98ZZZ0999',SepaMandateId='5001549101000002',Status='1')",
      "MandatSet(Application='1',SepaCreditorId='DE98ZZZ0999',SepaMandateId='5001549101000003',Status='1')"
  ]
  </code></pre>
