title: PFQuery includeKey on array of dictionaries.
body: <p>I have a <code>parse</code> class with a <code>NSArray</code> column, it is an <code>array</code> of <code>dictionaries</code>, and inside that <code>dictionary</code>I have a <code>key</code> with a <code>pointer</code> to another class. I'm trying to use <code>includeKey</code> but it is not working. I'm hoping to get the <code>objects</code> inside <code>pointers</code> without calling <code>fetch</code>, since there are many, the <code>requests</code> could go up easily. </p>
  
  <p>I'm using: <code>[query includeKey:@"ingredients.item"];</code> Ingredients is an <code>NSArray</code> of <code>dictionaries</code>, it is a column in the main object. item is a <code>key</code> in the <code>dictionary</code> that stores <code>pointers</code>. </p>
  
  <pre><code>[{"item":{"__type":"Pointer","className":"NutricaoCatalogo","objectId":"aTnHD5ttUH"},"ingredientTitle":"Clara De Ovo Natural","portionIndex":"1","portionQuantity":200},
  </code></pre>
