One limitation of the Model tag is that if you supply one instance of a child tag in an <mx:Model> tag, there is no way for Flex to know if you intend it to be an array or a single property instance. You can work around this limitation by using an <mx:Object> tag instead of an <mx:Model> tag and declaring an <mx:Array> tag inside the <mx:Object> tag. As an added benefit, you can then dynamically add to the object creating an array of objects.
Here’’s the sample code:
-
<?xml version="1.0" encoding="utf-8"?>
-
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*">
-
-
<mx:Script>
-
<![CDATA[
-
-
public function addToModel():Void
-
{
-
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>
