[flexcoders] not sure why COLLECTION_CHANGE listener is not firing.

[Derrick Anderson]

Hi,  I'm using the Guasax framework in my application- and in my model I am
adding a collection change event listener, but it is never getting fired-
here is my code (is there something with adding event listeners in a
constructor maybe??)

*EmployeesModel.as*
package com.winn.model
{
    import com.winn.vo.EmployeeVO;

    import conf.Constants;

    import es.guasax.container.GuasaxContainer;
    import es.guasax.view.ViewLocator;

    import mx.collections.ArrayCollection;
    import mx.controls.Alert;
    import mx.events.CollectionEvent;

    public class EmployeesModel
    {
        private static var instance:EmployeesModel;
        public static function getInstance():EmployeesModel
        {
            if( instance==null ) instance = new EmployeesModel();
            return instance;
        }

        [Bindable] public var selectedEmployee:EmployeeVO;
        [Bindable] public var employeesList:ArrayCollection;
        [Bindable] public var employeeStatusList:ArrayCollection;

        public function EmployeesModel(){
            employeesList = new ArrayCollection();
            employeeStatusList = new ArrayCollection();

            *employeeStatusList.addEventListener (
CollectionEvent.COLLECTION_CHANGE,employeeStatusListChange );*
        }

       * public function
employeeStatusListChange(event:CollectionEvent):void
        {
            Alert.show('firing listener function');//never shows
            GuasaxContainer.getInstance().executeViewUpdate(

[ViewLocator.getInstance().getViewObject(Constants.EMPLOYEES_VIEW)],
                    'setEmployeeTypes',[]);
        }*
    }
}

now here is where I load content into that arrayCollection and expect to see
my listener function fire off

*EmployeeBO.as
private var employeesModel:EmployeesModel = EmployeesModel.getInstance();
*public function getEmployeesAuxData():void
        {
            var params:Array = [];

ServiceLocator.getInstance().executeService("employeeCFC","getEmployeesAuxData",params,employeesAuxDataHandler,faultHandler,this);
        }

        public function employeesAuxDataHandler(event:* = null ):void
        {
               *employeesModel.employeeStatusList =
event.result.EMPLOYEESTATUSES;//i assumed this would be enough to trigger
the collectionChange***
               //employeesModel.employeeStatusList.refresh();*//thought this
would make the collectionEvent fire, but didn't*
               employeesModel.employeeStatusList.dispatchEvent(new
CollectionEvent(CollectionEvent.COLLECTION_CHANGE));*//then tried to fire it
manually, but my listener is still never registered*
        }

can anybody see why it seems my event listener is never registered?

thanks,
d.
