RadWindowManager and RadAjaxPanel

[Fran]

I have a RadWindowManager with a RadWindow inside, and this RadWindow has a RadAjaxPanel: 

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
</telerik:RadScriptManager>

 <asp:Button ID="Button1" runat="server" Text="abrir" />

 <telerik:RadWindowManager ID="RadWindowManager1" runat="server">
    <Windows>
        <telerik:RadWindow ID="RadWindow1" runat="server" OpenerElementID="Button1">
            <ContentTemplate>
               <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
                   <asp:Button ID="Button2" runat="server" Text="Button" />
                </telerik:RadAjaxPanel>
            </ContentTemplate>
        </telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>

This gives the following error:

Unable to register UpdatePanel with ID. '$ C $ RadAjaxPanel1Panel RadWindow1' because did not register with ScriptManager.

how I can fix this?
thanks
