What you want to use is the mx:Object instead of mx:Model.
This example dynamically adds a new object to the mx:Object "test" each time
the button is clicked.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"; xmlns="*">
<mx:Script>
<![CDATA[
public var count:Number = 0;
public function addToModel():Void
{
var newRecord:Object = new Object();
newRecord.name = "Toby";
newRecord.sign = "Leo";
newRecord.birthYear = "1984";
test[ count++ ] = newRecord;
}
]]>
</mx:Script>
<mx:Object id="test"/>
<mx:Button label="Add" click="addToModel()"/>
<Inspect/>
</mx:Application>

Subject: [flexcoders] Multiple values in a data model
I have an application I am working on where the user can input
information into various text input fields layed out in a HBOX. If
the user needs to add another person for the input they click on an
add event that dynamically creates another row.
My question is what is the best way to tie multiple entries to the
data model? If there is only a one line entry it would be no problem,
but what do you do when you want a data model to hold mulitple
entries from dynamically created input fields to be re-used
throughout the app or sent back to the database?
Any suggestions would be appreciated.
Thanks,
