To get a typed object on the Flex side, there is nothing specific to do, you only need to correctly define : - in the CFC VO , all the <cfproperty>, Ex. : <cfproperty name="someString" type="String" /> - in the service CFC <cffunction>, the correct returnType, Ex. : returntype="com.mycompany.myapp.model.TestVO" - in the AS3 VO, the alias metadata, Ex. : [RemoteClass(alias="com.mycompany.myapp.model.TestVO")] - in the AS3 VO, all the public var properties Ex. : public var someString:String;
You might also check 2 things, to see what's going on : - on the ColdFusion server side, check the CF Adapter logs in CFusionMX7/runtime/logs/coldfusion-out.log, - on the Flex client side, install ServiceCapture, http://kevinlangdon.com/serviceCapture/, you will see if the returned objects are correctly typed.

All I seemt to get is a generic object on the Flex side. Do you have to run through a bunch of set functions to move the properties returned into a pre-existing .as typed object? Sorry for the noob question, but this one has been bugging me for a while. --- In flexcoders@yahoogroups.com, "Benoit Hediard" <[EMAIL PROTECTED]> wrote: > > Since some people seems to have issues to use the Flex/ColdFusion > connectivity, here is a sample app to test your connectivity. > > ------------------------ > ColdFusion / Server side > ------------------------ > > Save the following value object CFC in > {wwwroot}/com/mycompany/myapp/model/TestVO.cfc > <cfcomponent> > > <cfproperty name="someString" type="String" /> <cfproperty > name="someNumber" type="Numeric" /> > > <cffunction name="init" returntype="com.mycompany.myapp.model.TestVO"> > <cfscript> > this.someString = "test"; > this.someNumber = 0; > </cfscript> > <cfreturn this /> > </cffunction> > > </cfcomponent> > > Save the following remote service CFC in > {wwwroot}/com/mycompany/myapp/service/TestService.cfc > <cfcomponent> > > <cffunction name="getArray" access="remote" returntype="Array"> > <cfscript> > var data = arrayNew(1); > arrayAppend(data, createObject("component", > "com.mycompany.myapp.model.TestVO").init()); > arrayAppend(data, createObject("component", > "com.mycompany.myapp.model.TestVO").init()); > </cfscript> > <cfreturn data /> > </cffunction> > > <cffunction name="getStruct" access="remote" returntype="Struct"> > <cfscript> > var data = structNew(); > data.firstData = createObject("component", > "com.mycompany.myapp.model.TestVO").init(); > data.secondData = createObject("component", > "com.mycompany.myapp.model.TestVO").init(); > </cfscript> > <cfreturn data /> > </cffunction> > > <cffunction name="receiveAndReturnVO" access="remote" > returntype="com.mycompany.myapp.model.TestVO"> > <cfargument name="vo" type="com.mycompany.myapp.model.TestVO"> > <cfreturn arguments.vo> > </cffunction> > > </cfcomponent> > > ------------------ > Flex / Client side > ------------------ > > Save the following value object in {some test > project}/com/mycompany/myapp/model/TestVO.as > package com.mycompany.myapp.model { > > [Bindable] > [RemoteClass(alias="com.mycompany.myapp.model.TestVO")] > > public class TestVO { > > public var someString:String; > public var someNumber:int; > > public function TestVO() { > someString = ""; > someNumber = 0; > } > > } > > } > > Save the following test application in Flex Builder 2 {some test > project}/TestConnectivity.mxml <?xml version="1.0" encoding="utf-8"?> > <mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml"; xmlns="*"> > > <mx:RemoteObject id="testService" > destination="ColdFusion" > result="onResult(event)" > source="com.mycompany.myapp.service.TestService" /> > > <mx:Script> > <![CDATA[ > import com.mycompany.myapp.model.TestVO; > import mx.controls.Alert; > import mx.rpc.events.ResultEvent; > import mx.utils.ObjectUtil; > > private function onResult(event:ResultEvent){ > Alert.show(ObjectUtil.toString(event.result)); > } > ]]> > </mx:Script> > > <mx:Button label="getArray" click="testService.getArray()" /> > > <mx:Button label="getStruct" click="testService.getStruct()" /> > <!-- BUGS : display (null) value instead of objects, but objects are > correctly returned... --> > > <mx:Button label="receiveAndReturnVO" > click="testService.receiveAndReturnVO(new TestVO())" /> > > </mx:Application> > > Compile and run TestConnectivity.mxml (do not forget to set the > compile argument to take into account your flex/coldfusion service > definition, > "flex-enterprise-services.xml") > > It should work, if your ColdFusion server is correctly configured with the > Flex/ColdFusion connectivity add-on. > You can also check the adapter logs in > {CFusionMX7}/runtime/logs/coldfusion-out.log, very nice to see if the typed > objects are correctly received or sent by the ColdFusion adapter. > > ---- > BUGS > ---- > > We have faced several bugs with the Flex/ColdFusion connectivity. > > 1.
