Sending Value Objects from Railo & ColdFusion to Flex

Can you send VO's for Flex to Railo via remoting? Yes Railo 3.1.0.16 introduced working flashremoting between Flex and Railo cfc's I already have a post on sending simple datatypes between Railo and Flex so I wanted to make a slightly more complex example of sending Value Object from Flex to Railo and back.

I also demonstrate that you can place data into session via remoting. In the 2nd iframe you can see a dump of session and see the data passed back to flex and sent from flex.

Click "Send" or/and "Get" then reload the dump of session.

You can view the source here or right click and select view source on the Flex Example.

Person.as
<br /> package <br /> {<br /> [RemoteClass(alias="Person")]<br /> <br /> [Bindable]public class Person{ <br /> public var Name:String;<br /> public var Age:Number;<br /> public var aNumber:Number;<br /> <br /> public function Person():void{<br /> //Constructor<br /> }<br /> }<br /> }<br />

Person.cfc
<br /> <cfcomponent><br /> <cfproperty name="Name" type="String"><br /> <cfproperty name="Age" type="Numeric"><br /> <cfproperty name="aNumber" type="Numeric"><br /> </cfcomponent><br />

service.cfc
<br /> <cfcomponent><br /> <cffunction name="getPeople" access="remote" returntype="Person[]"><br /> <cfargument name="mySessionName" default="#rand()#" /><br /> <cfset StructClear(Session)> /><br /> <cfset var myArray = arrayNew(1) /><br /> <cfset var p = "" /><br /> <cfloop from="1" to="10" index="i"><br /> <cfset p = createObject('component','Person') /><br /> <cfset p.Name = "Person - #i#" /><br /> <cfset p.Age = randRange(1,99) /><br /> <cfset p.aNumber = i /><br /> <cfset arrayAppend(myArray,p) /><br /> </cfloop><br /> <cfset session[mySessionName] = myArray /><br /> <cfreturn myArray><br /> </cffunction><br /> <br /> <cffunction name="sendPerson" access="remote" returntype="void"><br /> <cfargument name="person" type="Person"><br /> <cfset session.person = arguments.person /><br /> </cffunction><br /> <br /> </cfcomponent>
The code will work on both Railo and ColdFusion
