Re Usage: The AjaxNotifcationCenter must come before any of the observed fields. In the example, I use the aboveDisplayPropertyKeys repetition to enforce that, but it could just as easily exist in displayPropertyKeys, as long as it is first. The observers register their generated id with the notification center, so it has to exist on the page first.
Notification objects are the d2wContext, so each nested page has its own ANC. The observers are just an Ajaxed D2WCustomComponent. So each dependent field needs a couple of rules like: int: qual => componentName = AjaxObservingSwitch int: qual => customComponentName = OriginalComponentName When properties change, they fire a notification and refresh the ANC. The ANC receives the notification and passes the current D2WContext to the propertyChangedDelegate object from the rule system. That tells the delegate which property changed (propertyKey) and the delegate then passes back an NSArray of propertyKeys that require a refresh. Re ERModern: I did the example in an ERNeutral project for kicks (^_^) But I also wanted to demonstrate the components can be used in any D2W look and work just the same. That includes ERModern. If added to Wonder, I think it would probably be best to put it in the AjaxLook framework. That way, anyone can use it, whether they choose Modern, Neutral, Diva, etc. Ramsey On Nov 28, 2010, at 9:07 AM, David Avendasora wrote: > Hi Ramsey! > > Wow.
