Hi Tim, I am also considering the benefits of using viewHelpers. Here's what i got out of it. "encapsulating all the logic necessary for interrogating and updating a particular View into a single helper class"
Why would the Command need to interrogate the View. A Command is always essentially created by the View and dispatched event data updates the Command. On Command remote handlers, the Command updates the model. I have been using explict setters on the view to initiate data-binding between model and view in mxml. Then it is View that is responsible for dispatching events throughout an application and that it is the View which will always drive the app. Regards Bjorn Schultheiss --- In flexcoders@yahoogroups.com, "Tim Hoff" <[EMAIL PROTECTED]> wrote: > > I've recently been toying with the concepts of ViewHelper vs. > ViewLocator.
