Data between mxml components

Question

I have a question about data between mxml components.
Product.mxml is the overview screen for the products and ProductDetail.mxml (it is a TitleWindow) the detail screen.
In the Product I define a value object ProductVo with all the data. When I click a record in the overview and click the button 'change' (changeProduct function) then a popup window appears with all the data in it.
Code in Product.mxml:
[Bindable]
public var myWin:ProductDatail;
private function changeProduct():void {
  myWin = PopUpManager.createPopUp(this, ProductDetail, true) as ProductDetail;
  myWin["btnSave"].addEventListener("click", save);
private function save(event:Event):void {
  productVo.productId = myWin.ti_productnr.text;
  productVo.name = myWin.ti_name.text;
  productVo.ean = myWin.ti_ean.text;
  ...some code to save the data in the db...
Code in ProductDetail.mxml:
[Bindable]
public var productDetailVo:ProductVo;
    <mx:Form>
        <mx:FormItem label="Productnr" required="true">
            <mx:TextInput id="ti_productnr" text="{productDetailVo.productId}" width="60"/>
        </mx:FormItem>
        <mx:FormItem label="Naam" required="true">
            <mx:TextInput id="ti_name" text="{productDetailVo.name}" width="200"/>
        </mx:FormItem>
        <mx:FormItem label="Ean">
            <mx:TextInput id="ti_ean" text="{productDetailVo.ean}" width="100"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <mx:Button id="btnSave" label="Save"/>
        </mx:FormItem>
    </mx:Form>
So my question: the save function in Product.mxml, is it possible to do this in a easier way instead of linking all the data from the form into the value object? Something like productVo = myWin.productDetailVo, but that does not work.

Answer 1

I just looked at the parsley framework and saw this code:
private function save():void
contact.firstName = firstName.text;
contact.lastName = lastName.text;
contact.email = email.text;
service.save(contact);
So, it is doing the same thing I'm doing.
I'm using Spring and hibernate on the server level, it is my own framework.
