- All Implemented Interfaces:
- java.io.Serializable, ViewFactory
- public abstract class Controller
- extends AbstractViewFactory
Base class useful for implementing controllers.
TODO resolve error-handling
currently this is performed during render phase
setting up the models should be performed during parse phase
during parse phase we can send all errors to the application
which can decide upon passing the user to an error page
how to load the models during parse phase?
when navigating to a new page an event should be sent to that page
ie. when changing the target of a named component link events should
be sent (they should be queued up to the next parse phase), the controller
adds a listener for this event (which probably could be performed by the
base class Controller with an abstract template method createModels() throws Exception)

public Controller(Application application)
public Application getApplication()
public View getView()
- This method is called by the framework at any time and any number of times during
the render phase.
To decrease memory usage and optimize serialization the view is transient and
referred using a weak reference. This implies that the createView method can be
called at any time recreating the view. The createView method thus need to be able to
completely restore the view and it's link to actualy persistent conversational state such
as the models which should be kept in a non-transient field.
