Accessing data from component

Question

Hello guys,
Based in one example of internet, I create one test
aplication in Flex to test the relationship of more than one
component, where:
==========================================================
mainComp.mxml
==========================================================
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
width="400" height="400" initialize="newItem('teste1');">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
private var __designItem:DesignItem;
public function newItem(newitem:String):void {
__designItem = DesignItemFactory.getItem(newitem)
for each (var item in __designItem.__items) {
Alert.show(item);
]]>
</mx:Script>
<mx:Button label="Button" click="newItem('teste2');"/>
</mx:Application>
==========================================================
==========================================================
DesignItemFactory.as
==========================================================
package {
public class DesignItemFactory {
import DesignItem;
static public function
getItem(i_item_name:String):DesignItem {
var newDesignItem:DesignItem = new DesignItem();
DesignItemFactory.addItems(i_item_name,newDesignItem);
return newDesignItem;
static private function
addItems(i_item_name:String,i_design_item:DesignItem):void {
i_design_item.addNewItem(i_item_name);
==========================================================
==========================================================
DesignItem.mxml
==========================================================
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
[Bindable]
public var __items:Array = new Array();
public function addNewItem(i_displayObject:String):void {
__items.push(i_displayObject);
]]>
</mx:Script>
</mx:Application>
==========================================================
The idea is starting from first file ("mainComp.mxml"),
insert data in array from third file ("DesignItem.mxml"), and store
in array (push)
public function addNewItem(i_displayObject:String):void {
__items.push(i_displayObject);
But, in array "for each", return only ONE element.
Please, someone can help me?
The principal idea is have one component (mxml) that store
data (like array, for example) and can be accessed from other
components.
Thanks a lot!

Kevin,
You have access to the entire XFAModel when customising a Guide in Flex and access the data using the same SOM expression you use in a LiveCycle PDF.
For example, if you LiveCycle form / data structure was like this:
     Blah
You can access this by the following (Xfa.instance is a static property - i.e. you don't have to instantiate the object):
var currentXfa:Xfa = Xfa.instance;
var myFieldObject = currentXfa.resolveNode("rootForm.myFirstPage.myField");
if (myFieldObject.rawValue == "") {
myFieldObject.rawValue = "aNewValue";
In answer to the second part of the question, anything you update in the XFA model in Flex will update the underlying PDF form / data too and vice versa (a script executed in the PDF will update the XFA model in Flex and these changes will be reflected in the Flex app fields). This is achieved by the "Adobe LiveCycle Forms Bridge" (you can see the source if you drag and drop it onto the form from the Custom library palette).
Hope this helps,
John.
