title: Multiple $inc updates in MongoDB
body: <p>Is it possible to update a single document by passing two $inc operators in a single update document?</p>
  
  <p>For example, I am trying to increment two different fields in a given document using the following update document:</p>
  
  <pre><code>{
      "$inc" : { "ViewAggregates.4d75b891842f2d3930cf7674" : 1 },
      "$inc" : { "ViewAggregates.Total" : 1 }
  }
  </code></pre>
  
  <p>No errors are thrown and the document is updated but only one of the fields has been incremented.  It is as if the server disregarded the first $inc operator and only the second was actually applied.</p>
  
  <p>Is this the intended\correct behavior or is there something I am missing?</p>
