Hi Jerry-
I use Cairngorm.
I would specify a property in a bindable final MyModel like so:
public var labelVisible:Boolean;
MyModel is then referenced as a property on bindable MyModelLocator (Singleton)
like so:
public var myModel:MyModel;
I then would make my custom component with the following in the script block:
<fx:Script>
<![CDATA[
import com.myPackage.MyModelLocator;
[Bindalbe] public var myModelLocator:MyModelLocator;
]]>
</fx:Script>
So now when I instantiate my custom component I pass in MyModelLocator and then
I can then use this variable in the label easily:
<Label
id="myLabel"
visible="{myModelLocator.myModel.labelVisible}"/>
You should do your processing in a distinct separate AS3 class to manipulate
mModelLocator.myModel.labelVisible within that class. Et Viola, the changes
percolate prefectly.
Hope this sheds some light.
