Hi
Our Web site is written on c# and running by Mono on the Linux platform. When
we've tried to update mono to version 2.4.2.3, we are faced with trouble which
we donot have on mono 2.0.1.

If we set the visibility of any container (which contains UpdatePanel) in the
page to false, then all AJAX UpdatePanels on the page stop to work.

Reproducible: Always

Steps to Reproduce:
Initial conditions

We have a page with some AJAX UpdatePanels, which are situated in different
containers.

----------sourse code-------------
public void chk_OnCheckedChanged(object sender, EventArgs e)
{
    chk.Text = chk.Checked.ToString();
}
-------------page------------------
<form id="form1" runat="server">
        <asp:ScriptManager ID="sm1" runat="server">
        </asp:ScriptManager>
        <div>
            <div id="div1" runat="server">
                <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                    <ContentTemplate>
                    </ContentTemplate>
                </asp:UpdatePanel>
            </div>
            <div id="div2" runat="server">
                <asp:UpdatePanel ID="UpdatePane2" runat="server">
                    <ContentTemplate>
                        <asp:CheckBox ID="chk" runat="server"
AutoPostBack="true" Text="False" OnCheckedChanged="chk_OnCheckedChanged" />
                    </ContentTemplate>
                </asp:UpdatePanel>
            </div>
        </div>
    </form>

1. Set the visibility of any container (which contains UpdatePanel) in the page
to false, for example

protected override void OnInit(EventArgs e)
{
    ...
    div1.Visible = false;
}
or
<div id="div1" runat="server" visible="false">

2.Click to checkbox.
Actual Results:  
Nothing happends (async postback isnot provided). If Visible = true then page
behaviour is correct.

Expected Results:  
async postback is provided and checkbox's text is changed.

used System.Web.Extensions with version=1.0.61025.0
