menubar

I have the following XML in my Flex4 (AIR) project that defines the start of my menu interface:

<mx:MenuBar x="0" y="0" width="100%" id="myMenuBar" labelField="@label" itemClick="menuChange(event)">
    <mx:dataProvider>
    <s:XMLListCollection>
    <fx:XMLList xmlns="">
        <menu label="File">
            <item label="New"/>
            <item label="Load"/>
            <item label="Save" enabled="false"/>
        </menu>
        <menu label="Help">
            <item label="About"/>
        </menu>
    </fx:XMLList>
    </s:XMLListCollection>
    </mx:dataProvider>
</mx:MenuBar>

I am trying to find the syntax that will let me set the save button to enabled=true after a file has been loaded by clicking "Load", however I can't figure out the syntax, can someone make a suggestion please.

Currently the way that button clicks are detected is by a Switch/Case testing the String result of the MenuEvent event.item.@label. Maybe this isn't the best way?
