Bind a Boolean variable inside an ArrayCollection

[Bindable]
public var isToggled:Boolean = true;

public var menuData:Array = [
    {label: "Sample", type: "check", toggled: {isToggled}}
];

I'm trying to bind the isToggled variable to the toggled property but I'm getting this error: 1084: Syntax error: expecting colon before dot. Maybe because it is treating {isToggled} as another object. Is there a workaround for this?

You can't have advantages of declarative data binding within ActionScript code. It is allowed only within MXML tags. But you can declare your Array or ArrayCollection with MXML:

<fx:Declarations>
    <s:ArrayCollection id="myCollection">
        <s:source>
            <fx:Array>
                <fx:Object label="Sample" type="check" toggled="{isToggled}" />
            </fx:Array>
        </s:source>
    </s:ArrayCollection>
</fx:Declarations>

You can't use bindings ('{}') outside of mxml unless you use BindingUtils. However, I wouldn't recommend that either because now you're copying your data.

Why do you need 2 boolean values? You already have the data just bind it using the menuData property.
