Hi Kristan,

I've not seen this error myself, but I know it happens because I keeping getting ELMAH emails from one of my client's Umbraco installs, (but can't replicate the exception).  It wasn't with a custom section, but the standard "editContent.aspx".

I thought is that it happens when you have multiple windows/tabs open ... but again I can't be sure!

Does it happen to you in different browsers? and does it happen all the time?

Curious if this happens to anyone else?

Cheers, Lee.

Hi Lee, yeah - happens constantly, all the time in all browsers....

The aspx looks like this

<asp:Content ID="Content1" ContentPlaceHolderID="body" runat="server">

    <cc1:TabView runat="server" ID="tabControl" Width="552px" Height="692px"/>

    <cc1:Pane ID="Pane1" runat="server" Height="600px" Width="330px">

        <SP:Poll runat="server" />            

    </cc1:Pane>

</asp:Content>

The SP poll contains gridview and detailsview controls

thanks!

It's all OK, I just had to add the controls to the Tab Pane

protected override void OnInit(EventArgs e)

        {

            // Tab setup

            FirstTab = tabControl.NewTabPage("First");

            FirstTab.Controls.Add(Pane1);

            Pane1.Controls.Add(GridView1);

            Pane1.Controls.Add(DetailsView1);

            Pane1.Controls.Add(EntityDataSource1);

            Pane1.Controls.Add(EntityDataSource2);

            base.OnInit(e);

        }

Plus, i think the other option would have been to remove the umbraco master page reference, so it's essentially a standard asp.net page in an iframe within the Umbraco custom section.

cheers
