Ext.Net RadioGroup CheckedItems is always null

Question

I'm seeing strange behaviour from Ext.Net 2.0: RadioGroup.CheckedItems is always zero in my change handler callback. In my code below RadioGroup1.CheckedItems is ALWAYS zero after checking. What am I doing wrong / how can I solve this?

[DirectMethod]
public void TxtVisibility()
{
    foreach (var item in RadioGroup1.CheckedItems)
    {
        if (item.ID == "rdHourly")
        {
            txtPerHour.Hidden = false;
            txtAtTime.Hidden = true;
        }
        else if (item.ID == "rdAtHourly")
        {
            txtPerHour.Hidden = true;
            txtAtTime.Hidden = false;
        }
    }  
}

My calling code:

<ext:RadioGroup ID="RadioGroup1" 
                runat="server" 
                FieldLabel="" 
                ColumnsNumber="1">
    <Items>
        <ext:Radio ID="rdHourly" FieldLabel="IsEveryPerHour"
                   Name="IsEveryPerHour" runat="server"
                   BoxLabel="Per Hour(s)" Padding="10">
        </ext:Radio>
        <ext:Radio ID="rdAtHourly" FieldLabel="IsAtHour"
                   Name="IsAtHour" runat="server"
                   BoxLabel="At" Padding="10">
       </ext:Radio>
    </Items>
    <Listeners>
         <Change Handler="App.direct.TxtVisibility();" ></Change>
    </Listeners>
</ext:RadioGroup>

I just answered this exact same question on the Ext.NET forums, then came over to Stack to see what's new today... and found this question.

You might need to wait for the next Ext.NET v2 release. Your sample appears to be working fine with the latest source. There's a complete working example at the link above.
