Cairngorm MVC Example

[mykidong]

Hi,

I am interested in using Spring Actionscript and Cairngorm MVC, thus I have followed Documentation 3.1.1. Cairngorm.
But it does not work.

The following configuration is what I followed the above chapter:

<?xml version="1.0" encoding="utf-8"?>
<objects xmlns="http://www.springactionscript.org/schema/objects" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    
	xsi:schemaLocation="http://www.springactionscript.org/schema/objects http://www.springactionscript.org/schema/objects/spring-actionscript-objects-1.0.xsd">


	<object id="appAwareCmdFactory" class="mykidong.command.ApplicationModelAwareCommandFactory">
		<property name="applicationModel" ref="applicationModel"/>
		<method-invocation name="addBusinessDelegateFactory">
			<arg>
				<ref>businessDelegateFactory</ref>
			</arg>
			<arg>
				<array>
					<value type="Class">mykidong.command.GetProductItemsCommand</value>
				</array>
			</arg>
		</method-invocation>
	</object>


	<object id="applicationModel" class="mykidong.model.ApplicationModel" singleton="true"/>
	
									
	<object id="moduleOneFrontController"
		class="org.springextensions.actionscript.cairngorm.control.CairngormFrontController">
		<constructor-arg>
			<object>				
				<property name="getProductItems" value="GetProductItemsCommand"/>
			</object>
		</constructor-arg>		
		<constructor-arg value="mykidong.command"/>
		<method-invocation name="addCommandFactory">
			<arg><ref>appAwareCmdFactory</ref></arg>
		</method-invocation>
	</object>		

    <!--
	<object id="frontcontrollerWireAgent" class="mykidong.controller.CairngormFrontControllerWireAgent">
		<constructor-arg>
			<dictionary>
				<entry key="myModule" value="moduleOneFrontController"/>
			</dictionary>
		</constructor-arg>
	</object>	

	<si:stageinterceptor target-object="frontcontrollerWireAgent" target-method="evaluate"
						object-selector="moduleSelector" id="stageInterceptor"/>

	<object id="moduleSelector"
			class="org.springextensions.actionscript.ioc.wire.TypeBasedObjectSelector">
		<constructor-arg>
			<array>
				<value type="class">mx.modules.Module</value>
			</array>
		</constructor-arg>
	</object>
	-->
	
	<object id="businessDelegateFactory"
		class="org.springextensions.actionscript.cairngorm.business.BusinessDelegateFactory">
		<property name="service" ref="testService"/>
		<property name="delegateClass" type="class" value="mykidong.service.GetProductItemsDelegate"></property>
	</object>

	
	<object id="serviceLocator"
		class="org.springextensions.actionscript.cairngorm.business.CairngormServiceLocator"
		factory-method="getInstance">
		<property name="testService">
			<ref>testService</ref>
		</property>
	</object>
	
	<object id="testService" template="remoteObject">
		<param name="serviceClass" value="someservice"/>
	</object>
	
	<template id="remoteObject">
		<object class="mx.rpc.remoting.mxml.RemoteObject">
			<property name="destination" value="ColdFusion"/>
			<property name="source" value="com.myremoteobjects.${serviceClass}"/>
			<property name="channelSet">
				<ref>channelset</ref>
			</property>
		</object>
	</template>
	
	<object id="amfChannel" class="mx.messaging.channels.AMFChannel">
		<constructor-arg value="my-amf"/>
		<constructor-arg value="http://{server.name}:{server.port}/flex2gateway/" />
		<property name="id" value="amfChannel"/>
		<property name="pollingEnabled" value="false"/>
	</object>
	
	<object id="channelset" class="mx.messaging.ChannelSet">
		<method-invocation name="addChannel">
			<arg>
				<ref>amfChannel</ref>
			</arg>
		</method-invocation>
	</object>		
	
</objects>

And in my main mxml, application context is loaded and dispatch an event to show some product items like this:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
				xmlns:control="mykidong.controller.*"			
				xmlns:view="mykidong.view.*"			
				creationComplete="onCreationComplete();"
				pageTitle="CairngormPlayList"
				width="100%"
				height="100%"
				styleName="main"
				horizontalAlign="center">

	<mx:Script>
		<![CDATA[		
			import mx.rpc.remoting.mxml.RemoteObject;
			
			import org.springextensions.actionscript.context.support.FlexXMLApplicationContext;

			private var _remoteObject:RemoteObject;
			
			[Bindable]
			private var _model:IApplicationModel;
			
			private var _commands:Array = [GetProductItemsCommand];			

			private var _applicationContext:FlexXMLApplicationContext;

			private function onCreationComplete():void {
				_applicationContext = new FlexXMLApplicationContext("application-context.xml");
				_applicationContext.addEventListener(Event.COMPLETE, onApplicationContextComplete);
				_applicationContext.load();				
					
				_model = _applicationContext.getObject("applicationModel") as IApplicationModel;				
			}

			private function onApplicationContextComplete(event:Event):void {
				var getProductItemsEvent:GetProductItemsEvent = new GetProductItemsEvent();		
				getProductItemsEvent.dispatch();								
			}
		
		]]>
	</mx:Script>

	<!-- ========================================================================== -->

	<mx:Label text="Cairngorm" />
	
	<mx:Panel x="10" y="10" width="650" height="230" layout="vertical">   	    
		<mx:DataGrid dataProvider="{_model.productItems}" width="100%" height="100%"/>			
	</mx:Panel>	
</mx:Application>

I have no idea where it went wrong.

I have downloaded cairngorm sample from svn, CairngormStore, which works fine, but this sample codes have not been changed to What is mentioned in documentation 3.1.1.
Could I get some example with using Spring ActionScript and Cairngorm like in doc 3.1.1. ?

Hi Kidong,

I suspect the id of your event doesn't match up with your controller configuration. Can you post the source code of the getProductItemsEvent?

thanks in advance,

cheers,

Roland

Hi Roland,

thank you for your reply.

I have struggled with my problem for some time, and I got success.
In fact, I got some idea from the following link in the form:
http://forum.springsource.org/showthread.php?t=74133

, with the thread title 'Spring ActionScript + Cairngorm Example and Questions'.

I have attached my sample zip 'cairngorm-springas-sample.zip', in which flex application with cairngorm + spring actionscript, and remoting data service application with spring blaze DS are involved.

As I mentioned before, I could not get started easily to have cairngorm mvc + spring actionscript just with spring actionscript documentation. I think, it would be helpful that there is a good sample for that.

Dear Kidong,

thank you for saving me (and probably others) a lot of frustration with that example!

kudos,
