Question

coldfusion 8 Cfselect bind on two fields does not work in cfform

Asked by: cbeverly

I am trying to get 2 form fields to bind together:School state and student school using cfselect and a cfc. If a user picks a different state I only want the schools to show in that state. The first field (state) returns the dropdown list fine but the second field (student school)  that is dependent on the state selection above it won't show anything and gives me the error message:

Bind failed. Element not found:statesel

<cfselect name="statesel" id="statesel" bind="cfc:collections.getstates()" bindonload="true" value= "school_state" display= "school_state">  
             <option value = "">Select State</option>
       </cfselect> 
		p class="noindent">Student School</p        
		<cfselect  name="school" id="school" bind="cfc:collections.getSchool({statesel})" value= "school_name" display="school_name" bindOnLoad="true" />  
 
 
<cfcomponent output="false">
 
<cffunction access="remote" name="getStates" returntype="query">
       <cfquery name="qstates" datasource="education">
(SELECT 'Select State' AS school_state, 1 AS sortcol
FROM schools)
UNION
(SELECT DISTINCT s.school_state, 2 AS sortcol
FROM studentPodcasts sp
INNER JOIN schools s ON sp.student_school_id=s.id
WHERE s.school_state <> '')
ORDER BY sortcol, s.school_state
</cfquery>
	<cfreturn qstates>
</cffunction>
 
<cffunction access="remote" name="getSchool" returntype="query">
 <cfargument name="statesel" type="string" required="true">
 <cfset var data="">
 <cfquery name="data" datasource="education">
        select distinct school_name
        from schools
        where school_state LIKE '#ARGUMENTS.statesel#'
		order by school_name
        </cfquery>
      <cfreturn data>  
</cffunction>     
 
 
</cfcomponent>
