cfgrid bug? format="html" doesn't pass values

Using the example found at (http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c24 -7acf.html) when format="html" is added to the cfgrid tag the values passed are  lost.  Is there a workaround for this problem?  This problem occurs with more complex data, for simplicity sake the following code was used:

<cfquery name="empdata" datasource="cfdocexamples"> 
    SELECT * FROM Employee 
</cfquery> 
 
<cfform name="GridForm" 
    action="handle_grid.cfm"> 
 
    <cfgrid name="employee_grid" 
        height=425 
        width=300 
        vspace=10 
        selectmode="edit" 
        query="empdata" 
        insert="Yes" 
        delete="Yes"> 
         
        <cfgridcolumn name="Emp_ID" 
            header="Emp ID" 
            width=50 
            headeralign="center" 
            headerbold="Yes" 
            select="No"> 
 
        <cfgridcolumn name="LastName" 
            header="Last Name" 
            width=100 
            headeralign="center" 
            headerbold="Yes"> 
 
        <cfgridcolumn name="Dept_ID" 
            header="Dept" 
            width=35 
            headeralign="center" 
            headerbold="Yes"> 
 
    </cfgrid> 
    <br> 
    <cfinput name="submitit" type="Submit" value="Submit"> 

</cfform>
