I have a chart controlled by a fairly complex set of parameters. Within the model layer I would like to compose bindable objects, eg
Value1 value:Number; units:String; Value2 value:Number; units:String; Parameters value1:Value1; value2:Value2; such that view controls can bind to parameters.value1.units, for example, but an event would also be dispatched indicating that "value1Changed" or even "parametersChanged". Is there an approach better than having Parameters add listeners for PropertyChangeEvents to value1 and value2? Is this a good use for ChangeWatcher? I've yet to use that class, though I do use the Observe tag in MXML. Thanks.
