In constructing my test case, I couldn't replicate the problem entirely: it now fires the event once if Single="true" but it still is fired multiple times if Single="false". Here's what I have:
WebForm1.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WIS.WebForm1" Trace="true" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<%@ Register Src="~/WebUserControl1.ascx" TagName="WebUserControl1" TagPrefix="test" %>
<script runat="server">
protected void ServerBusEvent(object sender, DirectEventArgs e)
{
this.Panel2.Body.CreateChild(new DomObject
{
Html = "received message from usercontrol",
Tag = HtmlTextWriterTag.P,
CustomConfig =
{
new ConfigItem("style", "color:green;", ParameterMode.Value)
}
});
}
</script>

}
}
