Hi guys,
the JSF 2.2 has introduced a new feature of stateless views. It is done by setting a
transient attribute of f:view to true. All components in such tree become stateless.
Some features of using stateless views [1, 2]:
* It should bring memory and performance advantages (bigger views -> bigger
advantage).
* Preventing of view expired exceptions.
(* The @ViewScoped bean in such view will behave like @RequestScoped.)
* no state is saved and applied to components
Questions:
How should we test this feature with RichFaces components and which components should be
tested?
Some components will probably not fully work since they are dependent on its state
(tables?), how do we handle this? By throwing an exception?
Regards,
JS

I +expect+ all our components to behave correctly in stateless views. If they do not, we
should consider it a bug, unless it's for a truly exceptional circumstance.
I recommend changing the showcase or metamer to sue staeless views and testing all
components. We can then consider how to address any failures once we know the scope of
the problem.

Basically every RichFaces component is supposed to work in stateless mode,
even though it can be ineffectively.
I.e. every component should keep functioning properly when switching a view
from non-transient to transient,
but it is possible that slight modification of an app will be necessary
(.e.g change of scopes).
I.e. we shouldn't have components that are not able to run in transient
mode in under at least one configuration.
