Hello,
I have similar problem and im totally new to flex and cairngorm... here is
my code snippet:
im my java end:
List<Users> getAll() { // from hibernate dao then return result which
llist of users }
in AS files:
public class ListDelegate extends EventDispatcher
{
private var userService:RemoteObject;
private var responder:IResponder;
public function ListDelegate(responder:IResponder)
{
this.userService = new RemoteObject("userService");
this.responder = responder;
}
public function getUserList():void
{
var call : Object = userService.getAll();
call.addResponder( responder );
}
}
public class ListUserCommand extends BaseCommand
{
override protected function callDelegate():void
{
var listdelegate:ListDelegate = new ListDelegate(this);
listdelegate.getUserList();
}
override public function result( event : Object ) : void
{
this.modelHelper.onResultUser(event);
}
override public function fault( event : Object ) : void
{
var faultevt:FaultEvent = event as FaultEvent;
Alert.show(faultevt.fault.rootCause.toString());
}
}
public class ModelHelper
{
[Bindable]
public var userlist: UserList;
public function ModelHelper(userlist: UserList)
{
this.userlist = userlist;
}
public function getUserList():void
{
new ListUserEvent(this).dispatch();
}
public function onResultUser(event:Object):void
{
this.userlist.listusers = event.result as
ArrayCollection;
}
}
..and i use DataGrid to display datas:
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml";
initialize="init()"
creationComplete="loadAll()" >
<mx:Script>
<![CDATA[
import com.test.flex.util.UserList;
import mx.rpc.events.ResultEvent;
import com.test.flex.model.ViewModelLocator;
import com.test.flex.events.ListUserEvent;
import com.test.flex.model.ModelHelper;
[Bindable]
private var modelLocator:ViewModelLocator =
ViewModelLocator.getInstance();
[Bindable]
public var modelHelper:ModelHelper;
[Bindable]
public var users:UserList;
public function init():void
{
this.users = new UserList();
this.modelHelper = new ModelHelper(users);
}
public function loadAll():void
{
this.modelHelper.getUserList();
}
]]>
</mx:Script>
<!-- mx:Label text="{modelLocator.test}"/ -->
<mx:DataGrid id="userlist" dataProvider="{modelHelper.userlist.listusers}">
<mx:columns>
<mx:DataGridColumn headerText="ID" dataField="id"/>
<mx:DataGridColumn headerText="Username" dataField="username"/>
<mx:DataGridColumn headerText="Password" dataField="password"/>
</mx:columns>
</mx:DataGrid>
<mx:Button id="logout" label="LogOut"
click="{modelLocator.modelWorkflowState = ViewModelLocator.LOGIN_SCREEN}"/>
</mx:VBox>
..and the rest are straigthforward code. When I change the return value to
String it works fine nut when put it back to List it display nothing or
error i get but when i debug it i gets the results:
11:20:14,459 INFO [STDOUT] Hibernate: select this_.ID as ID1_0_,

What im missing here?
Thanks a lot.
