[flexcoders] MenuBar and Cairngorm

[Mozilla By]

Hi all, I need to enable and disable menu items in dependency of model changing. What the best practices to do this? Thanks   Now I use something like this for example:   <?xml version="1.0" encoding="utf-8"?> <mx:MenuBar                 xmlns:mx="http://www.adobe.com/2006/mxml"                 labelField="@label"                 itemClick="handleMenuBar(event)"                 dataProvider="{getMenuBar(                                models.currentView,                                models.currentFolder)}">                 <mx:Script>                                <![CDATA[                                                import com.adobe.cairngorm.control.CairngormEventDispatcher;
