Hi Cliff,
The new ViewHelper class no longer supports the view attribute as a
public variable. The class now takes advantage of the built in 'id'
tag, hence your ViewHelper declaration now becomes this:
<myView:AppViewHelper id="appViewHelper" />
By extending mx.core.MXMLObject the ViewHelper super class can
leverage the initialized event by creating an initialized function.
Rather than directly passing a reference to the component using
view="{this}", the initialized method already receives a 'view' object
(the MXML document that created the view helper) and an 'id' which is
used by the document to refer to your viewhelper object.
On initialization the ViewHelper is registered with a ViewLocator and
an 'unload' event is delegated to a local method which unregisters the
viewhelper, allowing it to be re-registered at a later time (popup
window is a good example).
Good question, hope all this helps.
