Hi all, I am getting bellow error while running my xhtml page.

java.lang.ClassCastException: com.infragistics.faces.grid.component.GridView cannot be cast to com.infragistics.faces.grid.component.html.HtmlGridView

My grid code is as below which is included in a xhtml page.

 <fieldset xmlns:f="http://java.sun.com/jsf/core"
 xmlns:c="http://java.sun.com/jstl/core"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:a4j="http://richfaces.org/a4j"
 xmlns:ig="http://ko.infragistics.com/faces/netadvantage"
 style="width: 100%; border: 0px;">

<table width="100%" border="0" cellpadding="0" cellspacing="0">
 <tr>
  <td>
  <div style="height: 204px; width: 726px; overflow-x: auto;">
  <ig:gridView
   id="myGrid" binding="#{gridbean.myGrid}"
   dataSource="#{gridbean.gridDataModel}"
   pageSize="0" sortingMode="multi" resizableColumns="true"
   columnHeaderStyleclass="igGridColumnHeader" style="height:204px;width: 726px;">
.

.

And my bean code is

import  com.infragistics.faces.shared.enumeration.ExportFormat;

import com.infragistics.faces.shared.enumeration.DataToExport;

import  com.infragistics.faces.grid.component.GridView;

 
private GridView myGrid= new GridView();
private ListDataModel gridDataModel;
 

with its getter and setter

But while ruuning the page its getting cust call exception,

could anyabody plz help why it is happening?

If I use  import com.infragistics.faces.grid.component.html.HtmlGridView; 
 then its working fine, but while going to export the data its showing exception again.
