Why not just pass the source attribute of the ArrayCollection? That's the actual data itself. Then you don't have to worry about what datatype you're dealing with. Jeff

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

like following

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');
}

Alert.show(event.fault.message);

<mx:RemoteObject

<mx:method name="send"

<mx:DataGrid id="myGrid"

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
