[flexcoders] Re: How to pass Flex ArrayCollection to Coldfusion CFC?

Tue, 25 Mar 2008 12:00:58 -0700

If I remember correctly Coldfusion reads array collections  as an Array of arrays (2d array).  CFDump should enlighten us a bit.

Try this as your cfc code and read the returned string as html/_javascript_.

<cfcomponent displayname="TestProcess" output="false" >
    <cffunction name="sendData" access="remote" output="false" returntype="String">
        <cfargument name="personQ" type="Any" required="true" />
        <cfset var mydump=""/><!--- Read up on var-scoping your cffunction variables--->
        <cfsavecontent name="mydump">
            <cfdump var="#arguments.personQ#"/>
        </cfsavecontent>
        <cfreturn mydump />
    </cffunction>
</cfcomponent>

Hi,

I try to pass flex ArrayCollection to coldfusion cfc like following

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical">
<mx:Script>
<![CDATA[
import mx.controls.Alert;

import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
import mx.rpc.events.FaultEvent;
import mx.events.ValidationResultEvent;

[Bindable]
private var myAC:ArrayCollection = new ArrayCollection([
{id:89, Contact: 'Bob Jones' },
{id:5, Contact: 'Jane Smith' },
{id:7, Contact: 'Doug Johnson' },
{id:15, Contact: 'John Jackson'}
]);

public function send():void {
cfdata.sendData(myAC);
}


public function send_Result(event:ResultEvent):void {
Alert.show('ok');
}

public function send_Fault(event:FaultEvent):void {
Alert.show(event.fault.message);
}



]]>
</mx:Script>

<mx:RemoteObject
id="cfdata" showBusyCursor="true"
destination="ColdFusion"
source="debug.cfc.test">
<mx:method name="send"
result="send_Result(event)"
fault="send_Fault(event)" />
</mx:RemoteObject>

<mx:DataGrid id="myGrid"
dataProvider="{myAC}" editable="true" >
<mx:columns>
<mx:DataGridColumn dataField="id" width="150"
editable="false"/>
<mx:DataGridColumn dataField="Contact" width="150" />

</mx:columns>
</mx:DataGrid>
<mx:Button label="Update DB" click="send()"/>

</mx:Application>

This is the cfc:

<cfcomponent displayname="TestProcess" output="false" >

<cffunction name="sendData" access="remote" output="false"
returntype="true">
<cfargument name="personQ" type="query" required="true" />

<cfset process = true>
<cfreturn process />
</cffunction>
</cfcomponent>

I get following error message

The argument pass to function is not the type query.

Please let me know which data type I can use in cfc for the Flex
ArrayCollection

Thanks

Mark
