Binding Data to a CFTEXTAREA - coldfusion

Question

I am populating a cfselect box using the bind attribute. I'd like to be able to make my selection from the two drop downs and then populate a CFTEXTAREA based on that selection. I thought I could just issue a similar bind attribute command but the textarea outputs:
[object Object]
CF8 documentation says that this is possible? What am I missing?
Form Code:
<cfselect name="descriptionDD" value="description" bind="cfc:cfcs.menudata.getData()" bindonload="true" />
<cftextarea name="detailDD" value="service_detail" bind="cfc:cfcs.menudata.getDetail({descriptionDD})" bindonload="true" />
CFC Code:
<cfcomponent>
<!---First Select Box --->
<cffunction name="getData" access="remote" returntype="query">
<!--- Function to get data from datasource --->
<cfquery name="data" datasource="ezpay">
select description
from service_descriptions
order by description
</cfquery>
<!--- Return results --->
<cfreturn data>
</cffunction>
<!---Second Select Box --->
<cffunction name="getDetail" access="remote" returnType="query">
<cfargument name="description" type="any" required="true">
<cfquery name="dataDetail" datasource="ezpay">
SELECT service_detail
from service_descriptions
WHERE description = '#ARGUMENTS.description#'
ORDER BY ID ASC
</cfquery>
<cfreturn dataDetail>
</cffunction>
</cfcomponent>

Answer 1

but the textarea outputs: [object Object]
That usually means you are returning a complex object where a simple string is expected instead. [object Object] is essentially the string representation of the complex object (in your case a query).
TextArea's are designed to display a single value. So your bind function should return a string, not a query object.
<cffunction name="getDetail" access="remote" returnType="string">
<cfargument name="description" type="any" required="true">
<!--- localize function variables --->
<cfset var dataDetail = "">
<cfquery name="dataDetail" datasource="ezpay">
SELECT service_detail
FROM service_descriptions
<!--- adjust cfsqltype if needed --->
WHERE description = <cfqueryparam valu="#ARGUMENTS.description#" cfsqltype="cf_sql_varchar">
ORDER BY ID ASC
</cfquery>
<cfreturn dataDetail.service_detail>
</cffunction>
