title: ModX getResources displays child resources as well as parent level resources
body: <p>I have getResources call:</p>
  
  <pre><code>[[!getResources? &amp;parents=`[[*id]]` &amp;limit=`15` &amp;tpl=`contentsectiontpl` &amp;sortdir=`ASC` &amp;sortby=`menuindex` &amp;includeContent=`1`]]
  </code></pre>
  
  <p>In a parent resource.</p>
  
  <p>I wish to only display the child resources of this parent, but the above displays both the child resources, and the resources on the same level as the parent.</p>
  
  <p>Does anyone know the correct way to achieve displaying only the child resources without using the parents ID directly?</p>
