-----------------------------------------------------------
I have designed fix for this issue:
It is based on moving registration for
{{UIViewRoot#subscribeForViewEvent(...)}}
from constructor
to the {{PostAddToViewEvent}} time.
Component itself needs to register for events ({{PostAddToViewEvent}} and
{{PostRestoreStateEvent}}).

> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: component-tables
> Affects Versions: 4.1.0.CR2
> Reporter: Marius Bogoevici
> Assignee: Lukáš Fryč
> Priority: Critical
> Fix For: 4.1.1.Final
>
>
> The fix introduced for 4.1.0.CR1 by adding event registration to the
> constructor:
> {code}
> public UIDataAdaptor() {
> super();
>
> getFacesContext().getViewRoot().subscribeToViewEvent(PreRenderViewEvent.class,
> this);
> }
> {code}
> breaks when Spring Webflow restores the view in the middle of the flow with a
> NPE. E.g. when a data table is constructed, the viewRoot is not yet set on
> the current thread, which causes the exception above.
