Binding a CFC to cfselect box

I am creating a form and for what ever reason, when using a bindOnLoad with a remote CFC, my default value doesn't seem to appear.

Here is the cfselect:

<cfselect name="edcs"
          id="edcs"
          multiple="false"
          bind="cfc:Components.requestSearch.getEDCs()" 
          bindonload="true"
          value="edc_nm"
          display="edc_nm">
    <option name="">Select an EDC</option>
</cfselect>

And here is the function:

<cffunction name="getEDCs" access="remote" returntype="query">
    <cfscript>
        var queryService = new Query();
        queryService.setDatasource("#APPLICATION.db2system#");
        queryService.setName("getEDCs");
        queryService.setUserName("#APPLICATION.db2logon#");
        queryService.setPassword("#APPLICATION.db2pass#");
        queryService.setSQL(
                "select distinct rtrim(edc_nm) as edc_nm 
                   from #APPLICATION.db2owner#.pms_account");

        var result = queryService.execute();
        var edcs = result.getResult();          

        return("#edcs#");       
</cfscript>
</cffunction>

So, when the page loads I see the <option ...> value displayed for a split second and then the list gets populated, and the Select an ECD disappears. I need to have a choice for a null value, which is what the option is for. What am I doing wrong? Thanks.

Addition: According to the CF10 docs, I should be able to use the <option> html tag. http://help.adobe.com/en_US/ColdFusion/10.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-7afe.html

I've run across this issue with CFSELECTs and binding CFCs. I have also been unable to add an <option></option> tag with a bound CFSELECT. The best way would be to create the query and force the result to have the desired input on the top. For example:

SELECT distinct 
    rtrim(edc_nm) as edc_nm_display,
    rtrim(edc_nm) as edc_nm_value
FROM #APPLICATION.db2owner#.pms_account
UNION
SELECT
'Select an EDC' as edc_nm_display,
'0' as edc_nm_value
FROM dual
ORDER BY 2

This will return your query with 'Select an EDC' on the top. Also, as a check, I believe <option name="">Select an EDC</option> should be <option value="">Select an EDC</option>. I hope that helps.

Return is not a function ... 

return("#edcs#");

Try changing your function to ... 

var result = queryServices().execute().getResult();
return result;

The query will need to return that value. Try adding it as a UNION statement.
