title: drill down feature - call to a js function not working in fusioncharts
body: <p>I am invoking a javascript function for drilling down the chart.
  I tried using both methods specified:</p>
  
  <p>1) <code>&lt;set label='USA' value='235' link="j-myJS-empid"/&gt;</code>.</p>
  
  <p>2) <code>&lt;set label='S. Korea' value='86' link="JavaScript:myJS('empid');"/&gt;</code></p>
  
  <p>the first try gives me error that the resource -  /myapp/mychart/j-myJS-empid is unavailable.
  The second one just doesnot display the chart , says invalid XML data.</p>
  
  <p>I am using grails-groovy (java based) to develop my application.
  I am using the dataXML method to generate the charts like this</p>
  
  <pre><code>&lt;OBJECT style="z-index: -100" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" align="center" name="Column3D" width="440" height="350"
   codebase="http:/download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" id="Column3D"&gt;
   &lt;param name="movie" value="/gra/swf/FCF_Column3D.swf" /&gt;
   &lt;param name="FlashVars" value="&amp;dataXML=${dataXML}" /&gt;
   &lt;param name="quality" value="high" /&gt;
    &lt;param name="wmode" value="transparent" /&gt;
   &lt;param name="alpha" value="20" /&gt;
   &lt;param name="blendMode" value="BlendMode.ALPHA" /&gt;
  
        &lt;embed src="/gra/swf/FCF_Column3D.swf" style="text-align: center" flashVars="&amp;dataXML=${dataXML}"
         quality="high" width="440" height="350" name="Column3D" type="application/x-shockwave-flash"
         pluginspage="http://www.macromedia.com/go/getflashplayer" /&gt;
        &lt;/object&gt;
  </code></pre>
  
  <p>IS the javascript function cal supported only through dataURL method, if yes, I need to know if there is any other way to call a js function using dataXML method since I have many charts on the page and it wont be feasible to write the data to XML file for all.
  Also I wanted to know if there is a limit on the length of the URL specified in the link attribute
  P.S. I have succesfully invoked the JS call in my other chart where I use the dataURL method.
  Please hel is needed urgently.
  Thanks in advance
