This is F'ed up...
I changed my code to this...
public function handleChangeEvent(event:Event):void
{
var myVO:BudgetVO = new BudgetVO();
myVO.actiondate = event.target.selectedItem.actiondate;
myVO.amount = event.target.selectedItem.amount;
myVO.id = event.target.selectedItem.id;
...
var evt:BudgetEvent = new BudgetEvent(myVO, MyControl.EVENT_GET_BUDGET_DETAILS);
CairngormEventDispatcher.getInstance().dispatchEvent(evt);
}
public class GetBudgetDetailsCommand implements ICommand, IResponder
{
private var currentSelectedVO:BudgetVO = null;
public function execute(event:CairngormEvent):void {
MyModel.getInstance().SelectedBudgetAC = (event as BudgetEvent).budget
as ArrayCollection;
/* If I Alert the (event as BudgetEvent).budget.amount.toString() I
get the amount
But if I Alert
MyModel.getInstance().SelectedBudgetAC.getItemAt(0).amount.toString()
I get a null error.. matter of fact if I Alert
MyModel.getInstance().SelectedBudgetAC.toString()
I get a null error.. so where the hell is my data going? MyModel.as is
being imported into the command.
import com.model.MyModel
Again, inside MyModel.as I have the global vars..
public var SelectedBudgetAC:ArrayCollection;
to check to make sure the MyModel was loading properly I added another
var to it..
public var fooVar:Number = 0;
And if I alert that value in the execute() function, it Alerts "0" as
it should..
I'm lost
*/
Alert.show(MyModel.getInstance().fooVar.toString());
}
....
