JavaScript runtime error: Unable to get property 'load' of undefined or null reference
Hi:
I use loader in ext:window. I get JavaScript runtime error: Unable to get property 'load' of undefined or null reference. the debug stopped in the the compiled line: loader.load(Ext.applyIf({disableCaching:disableCac hing},loader.lastOptions||{}));},load:function(con fig){this.getLoader().load(config);},clearContent: function(){if(this.iframe&&this.iframe.dom){var me=this,doc,prop;this.iframe.un("load",this.getLoa der().afterIFrameLoad,this);try{doc=me.getDoc();if (doc){if(!Ext.isIE){Ext.EventManager.removeAll(doc );}
for(prop in doc){if(doc.hasOwnProperty&&doc.hasOwnProperty(pro p)){delete doc[prop];}}}
Can you tell what's wrong with it?
Here is my code:

Here is my code:
<ext:Window ID="winDocTypeKeywordList" runat="server" Title="Window" Frame="true"
Width="830" ConstrainHeader="true" Height="560" Maximizable="true" Closable="true"
Resizable="true" Modal="true" Hidden="true">
<Loader Url="../DocTypeKeywordList.aspx" Mode="Frame" runat="server" ID="LdKeyword" >
<Params>
<ext:Parameter Name="DocTypeID" Mode="Raw" Value="0">
</ext:Parameter>
</Params>
</Loader>
<Listeners>
<Hide Handler="this.clearContent();" />
</Listeners>
</ext:Window>
