I used a Webcombo instance of a filter page directly, using a SqlDataSource to bind to for the data and it works fine.

When I copy this same code into an ASCX file that is going to be used as a webpart component, it fails.

The webpart page is basically a container page with a table.  In this table it creates instances of ASP components.  One of those components is a copy of the code from our filter search page.  It is in this component where I have several instances of WebCombo.  When I type or drop the list down it loads for a long time and comes up empty.  If I check the javascript console I see that I'm repeatedly getting this error from WebCombo.js

'event' is null or not an object       WebCombo.js, line 7 character 31460

Below is a snippet from the outer container page where the component is added.  There is some other stuff on this page to and can add it if its neccessary to figure out why this isn't working.
<%@ Register Src="webparts/contractsearch.ascx" TagName="contractsearch" TagPrefix="exec" %>
<table>
<tr>
	<td id="tdLeft" runat="server" style="vertical-align:top; text-align:left; width:33%">
	    <tm:tmzwebpartzone id="wpzLeft" runat="server" headertext="Left" PartChromeType="TitleAndBorder" width="320px" PartStyle-CssClass="PartStyle" PartTitleStyle-CssClass="PartTitleStyle" PartChromeStyle-BorderColor="transparent" AllowShrink="false">
			<VerbStyle CssClass="gridheading" />
			<HeaderStyle BorderColor="black" borderstyle="solid" CssClass="leftnavselected" />
			<MenuPopupStyle  BackColor="white" BorderColor="black" BorderWidth="1px" GridLines="Horizontal" Font-Names="verdana" Font-Size="8pt" />
			<zonetemplate>	
			        <exec:contractsearch ID="contractSearch3" runat="server" Title="Contract Search" AuthorizationFilter="tmproductline=999"/>
			</zonetemplate>
	    </tm:tmwebpartzone>
    </td>
</tr>
</table>

 And here is the code for the component.
