title: Loading a jqgrid table using jsonstring datatype
body: <p>I would like to load a jqGrid table with a json String I produce from velocity; these are the table parameters: </p>
  
  <pre><code>var gridParams = {
      datatype: "jsonstring", 
      data: content,
      pager: $('#pagernav'), 
      rowNum: 5000,
      rownumbers: true,
      rowList: [50,100,200,500,1000,2000],
      ignoreCase: true,
      colNames: columns,
      colModel: tableColModel,
  }
  </code></pre>
  
  <p>The values of content and columns, when printed on the console are:</p>
  
  <pre><code>[{"ID":"7", "fname":"Bob", "addr":"18" }, {"ID":"8", "fname":"Sue" }]
  ["ID", "fname", "addr"]
  </code></pre>
  
  <p>Indeed the grid is created with the right columns, but it is empty...what is wrong with what I wrote? Thanks for your answers.</p>
