       </ext:Panel>
    when I clicked on the menu to insert the page the page is inserted but the component was not rendered at all. Even when I have just this on the page the same thing

     <ext:ResourceManager runat="server">
            <Listeners>
            
            </Listeners>
        </ext:ResourceManager>
        <div style="clear: both;">
        </div>
        <ext:Panel runat="server" Cls="items-view" Layout="fit" AutoHeight="true"
            Border="false" ID="Thepanel" IDMode="Explicit">
            <Items>
            <ext:Label runat="server" Text="Sample Text"></ext:Label>
    </Items>
            <Listeners>          
            </Listeners>
    
        </ext:Panel>
    </body>
    </html>

    When I debugged with firefox. The returned page is


        
    <body>   
        <div style="clear: both;">
        </div>
        <div id="Thepanel_Container"></div>
    </body>
    How can this issue be resolved. Strangely, I removed the dataview and added just a panel with an html attribute set to a string and the string was not rendered too. Seems like the ext component are not been processed.

    Hi,

    Please replace:
    rendererType : "iframe"
    with
    renderer : "frame"
    It works in the online example:
    http://examples2.ext.net/#/TabPanel/Basic/Add_Tabs/
    because there is "://" in the URL.

    Though I will replace with
    renderer : "frame"
    because "rendererType" is not used at all.
