title: Fusion Charts setCurrentRenderer('javascript') issue
body: <p>I have the following HTML code. It is working.</p>
  
  <pre><code>&lt;html&gt;
    &lt;head&gt;     
      &lt;title&gt;My First chart using FusionCharts - Using pure JavaScript&lt;/title&gt;    
  
      &lt;script type="text/javascript" src="http://www.fusioncharts.com/lib/jquery/jquery-1.6.2.min.js"&gt;&lt;/script&gt;
      &lt;script language="JavaScript" src="http://www.fusioncharts.com/lib/js/FusionCharts.js"&gt;&lt;/script&gt;
      &lt;script language="JavaScript" src="http://www.fusioncharts.com/lib/js/FusionCharts.HC.js"&gt;&lt;/script&gt;
      &lt;script language="JavaScript" src="http://www.fusioncharts.com/lib/js/FusionCharts.HC.Charts.js"&gt;&lt;/script&gt;
      &lt;script language="JavaScript" src="http://www.fusioncharts.com/lib/js/jquery.min.js"&gt;&lt;/script&gt;
  
    &lt;/head&gt;
    &lt;body&gt;     
      &lt;div id="chartContainer"&gt;FusionCharts will load here!&lt;/div&gt;          
      &lt;script type="text/javascript"&gt;
  
      //FusionCharts.setCurrentRenderer('javascript');
             var chartObj = new FusionCharts({
             swfUrl: "http://www.fusioncharts.com/demos/gallery/Charts/Column2D.swf",
             width: "500", 
             height: "300",
             id: 'sampleChart',
             dataSource: "http://www.fusioncharts.com/demos/gallery/Data/Col2D1.xml",
             dataFormat: FusionChartsDataFormats.XMLURL,           
             renderAt: 'chartContainer'
          }).render();
  
      &lt;/script&gt;        
    &lt;/body&gt; 
  &lt;/html&gt;
  </code></pre>
  
  <p>When I use the <code>setCurrentRenderer</code> javascripde mode. It gives me "no data to display".</p>
