[CLOSED] Fail to load frame

[RCN]

On the following example i would like to detect any failure on the load of frame such invalid URL, unavailable webpage, etc.

Unfortunately, no matter whether the page is loaded, the response parameter (Load Listener) is always null, so i was not able to check the http status.

<ext:Panel runat="server" Width="500" Height="500">
    <Loader Url="http://www.ext123131.net" Mode="Frame" ShowWarningOnFailure="true" runat="server">
        <Listeners>
            <Load Handler="alert('LOAD')" />
            <Exception Handler="alert('EXCEPTION')" />
        </Listeners>
    </Loader>
</ext:Panel>

Any ideas about how to overcome this issue?

Thanks in advance
