title: Liferay - Custom attributes are empty on staging
body: <p>I have an issue with getting the Values of my Custom Attributes (Site) in the Liferay Staging-Mode. </p>
  
  <p>I'm trying to get the Values with following Code in my Theme:</p>
  
  <pre><code>Map&lt;String, Serializable&gt; myAttributes = site.getExpandoBridge().getAttributes();
  </code></pre>
  
  <p>But the <strong>output on staging is empty:</strong></p>
  
  <pre><code>{custom-attribute-1=, custom-attribute-2=}
  </code></pre>
  
  <p>Output on Live:</p>
  
  <pre><code>{custom-attribute-1="mystring", custom-attribute-2="mystring"}
  </code></pre>
  
  <p>I'm using Liferay 6.2+</p>
  
  <p>Do you have any ideas? Thank You!</p>
