Re: [flexcoders] Re: Looking for examples of command chaining in Parsley 2.4
I'm using Parsley 2.4 and following the 2.4 documentation the [CommandXXX] metatags (aysnchronous command methods section 6.9) are no longer recommended. I've be using DynamicObjects (short-lived command objects section 6.10) and none of ArtInFlex's examples use the asynchronous command methods. And since I'm new to Parsley, I'll be following all recommendations where possible.

RE: [flexcoders] Re: Looking for examples of command chaining in Parsley 2.4
If you are using short-lived command objects, just dispatch an event from the result function of the command class to trigger the execution of the next command in the chain.Can you provide a simple use case showing what you are trying to achieve and how you are doing it?

Re: [flexcoders] Re: Looking for examples of command chaining in Parsley 2.4
I've tried both creating commands in the result handler and by using
the Task framework. I like the Task framework because it's more
modular in that it helps keep the commands independent. Having said
that, I'm having problems getting it working.
I created a task per command and each task dispatches the message for
the command and wait for the results. Then I've created a sequential
task group and added each task and then start the group. Here is an
example of one of my tasks:-
package mytasks
{
import org.spicefactory.lib.task.Task;
import org.spicefactory.parsley.asconfig.ActionScriptContextBuilder;
import MyMessage;
import MyModel;
public class MyTask extends Task
{
[Inject(id=myModel)] [Bindable]
public var myModel:MyModel;
[MessageDispatcher]
public var messageDispatcher:Function;
public function MyTask()
{
super();
ActionScriptContextBuilder.build(MyConfig);
}
protected override function doStart():void {
messageDispatcher(new MyMessage());
}
[MessageHandler]
public function handleMyMessage(message:MyMessage):void {
if (message.success == true) {
myModel.debug = success;
complete();
} else {
error(my task failed);
}
}
}
}
And my configuration file contains:-
model:MyModel id=myModel/
spicefactory:DynamicCommand type={MyCommand} selector=execute
result=handleResult error=handleError/
My command is:-
package mycommands
{
import mx.controls.Alert;
import mx.collections.ArrayCollection;
import mx.rpc.AsyncToken;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.remoting.RemoteObject;
import MyMessage;
import MyModel;
public class MyCommand {
[Inject(id=ro)]
public var service:RemoteObject;
[Inject(id=myModel)]
public var myModel:MyModel;
public function execute (message:MyMessage) : AsyncToken {
return service.getRemoteData(myModel.id);
}
public function handleResult(result:ResultEvent,
message:MyMessage):void {
if (result.result != null) {
myModel.dataCollection = result.result as ArrayCollection;
message.success = true;
}
}
public function handleError(fault:FaultEvent, trigger:MyMessage):void {
Alert.show(fault.toString());
}
}
}
But when I run this I get value is not a function.
So what have I missed or left out?
Chris
