I have drastically simplified my code and cannot figure out a bug that is now happening.

I have a combobox and once values have been selected it goes away and the child gets populated.  I have 100s of these and they work fine.  Now that I've upgraded to Q3 2012 I am finding that when the child combo box has checkboxes I run into issues.

The combo still works and gets populated with the data but when I click on one of the checkboxes the text doesn't appear in the combo box line

BTW your support page is showing a 403 error...

Basic code is as follows: 

<telerik:RadAjaxManager ID="uxRadAjaxManager" runat="server">
        <telerik:AjaxSetting AjaxControlID="uxClient">
                <telerik:AjaxUpdatedControl ControlID="uxPortfolio" />
<telerik:RadComboBox ID="uxClient" Runat="server" AllowCustomText="true" CssClass="halfWidthComboBox"
onclientselectedindexchanging="LoadClientChildren" onitemsrequested="uxClient_ItemsRequested" MarkFirstMatch="True"></telerik:RadComboBox>
<br />
<telerik:RadComboBox ID="uxPortfolio" Runat="server" CheckBoxes="true" EnableCheckAllItemsCheckBox="true"
onitemsrequested="uxPortfolio_ItemsRequested" MarkFirstMatch="True"

Hello Jon,

I am afraid that simultaneous usage of CheckBoxes and LoadOnDemand is not a supported scenario.
