title: jqGrid setselection true not work
body: <p>I have a jgGrid with a list of object, I want to select all rows on load page.
  This is my code </p>
  
  <pre><code>multiselect: true,
  loadComplete: function(){   
       var ids = $("#listDaFatturare").jqGrid('getDataIDs');
       for(var i = 0; i &lt;= ids.length; i++){
          $("#list").jqGrid('setSelection', i, true);
        }
   },
  </code></pre>
  
  <p>But don't run, In my view I see selected only one row. 
  I don't understand where is the problem, I try to debug the code and apparently there are no problems.</p>
  
  <p>Any ideas?</p>
