Just started working on ASP.NET 1.1 app. Requirement is to have popup dialog which hosts ascx control. I have built a control
<%@ Control Language="vb" AutoEventWireup="false" Codebehind="LabelAddEditDialog.ascx.vb" Inherits="CaseManagement.LabelAddEditDialog" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<%@ Register TagPrefix="eo" Namespace="EO.Web" Assembly="EO.Web" %>
<%@ Register TagPrefix="bv" TagName="LabelAddEdit" Src="~/UserControls/LabelAddEdit.ascx" %>
<script lang="javascript">
function onDialogResize(DialogBox)
{
}
</script>
<style>
IMG { MARGIN-TOP: 0px; MARGIN-LEFT: 0px; MARGIN-RIGHT: 0px }
</style>
<eo:callbackpanel id="CallbackPanel1" runat="server" Triggers="{ControlID:lbLabelEditSelection_Show;Parameter:},{ControlID:dlgLabelEditSelection;Parameter:}">
<DIV id="divMainLabelEditSelection">
<DIV id="divLabelEditSelection_ShowSelection">
<asp:linkbutton id="lbLabelEditSelection_Show" runat="server" CausesValidation="False">Label Edit</asp:linkbutton></DIV>
<eo:dialog id="dlgLabelEditSelection" onresize="onDialogResize(this)" runat="server" ResizeImageUrl="00020014"
RestoreButtonUrl="00070103" BackColor="White">
<HeaderStyleActive CssText="padding-right: 4px; padding-left: 4px; font-size: 11px; background-image: url(00070104); padding-bottom: 3px; padding-top: 3px; font-family: tahoma"></HeaderStyleActive>
<ContentTemplate>
<bv:LabelAddEdit id="ucLabelAddEdit" runat="server"/>
</ContentTemplate>
<FooterTemplate>
<asp:Button id="btnLabelEditSelectionOk" runat="server" Width="60px" Text="OK" CausesValidation="False"></asp:Button>
<asp:Button id="btnLabelEditSelectionCancel" runat="server" Width="60px" Text="Cancel" Visible="true"
CausesValidation="False"></asp:Button>
</FooterTemplate>
</eo:dialog></DIV>
</eo:callbackpanel>
which works fine if is the last control on page, as such
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="ProcHistorySearch.ascx.vb" Inherits="CaseManagement.UserControls.ProcHistorySearch" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<%@ Register TagPrefix="bv" TagName="ProcHistorySearchResult" Src="~/UserControls/ProcHistorySearchResult.ascx" %>
<%@ Register TagPrefix="bv" TagName="ProcHistorySearchInput" Src="~/UserControls/ProcHistorySearchInput.ascx" %>
<%@ Register TagPrefix="bv" TagName="lu" Src="~/UserControls/Dialogs/LabelAddEditDialog.ascx" %>
<asp:Panel ID="Something" Runat="server">
<TABLE cellSpacing="0" cellPadding="0">
<TR class="TitleRow">
<TD class="TitleText" colSpan="3">Procedural History Search
</TD>
</TR>
<TR>
<TD>
<bv:ProcHistorySearchInput id="ucProcHistorySearchInput" runat="server"></bv:ProcHistorySearchInput>
<bv:ProcHistorySearchResult id="ucProcHistorySearchResult" runat="server" visible="false"></bv:ProcHistorySearchResult>
</TD>
</TR>
</TABLE>
</asp:Panel>
<bv:lu id="lae" runat="server" />
If I add to end of page a second instance
<bv:lu id="Lu1" runat="server" />
I receive:

I have tried all kinds of different things.
If I replace <ContentTemplate> tag with anything else it fails the same, EXCEPT for EO treeview. I tried html elements, asp controls, other EO objects such as calendar and colorpicker, to no avail.
Aside: I can put different second control with same <eo:callbackpanel>/<eo:dialog> tags(in other words, hosting a different ascx control), and it still fails.
Thanks for any help!
