> I have an extendedDataTable with a datascroller. The first page of results
> displays correctly, but on pressing the control for page 2 (or any other)
> nothing happens. Using a4j:log I see that the ajax response to the post
> request contains a java.lang.NullPointerException.
> On reverting to 4.0.0.Final it works successfully. The problem also affects
> a rich:dataTable. I've not been able to locate the M2 release in the Maven
> repo to test it.
> The extendedDataTable value attribute value is a straightforward List<Event>
> where Event is a standard pojo. I was using ExtendedDataModel but removed
> this code to eliminate this as a cause.
