> The current process for pagination uses direct method for gathering data.
> Without any checks, validations and convertations.
> {code:java}
> public class DataContext extends BaseContext{

> public ResultIterator performIteratedQuery(Query query)
> }{code}
> {code:java}
> public class IncrementalFaultList<E> implements List<E>, Serializable {
> ...
> protected void fillIn(final Query query, List<Object> elementsList) {
> elementsList.clear();
> try (ResultIterator<?> it = dataContext.performIteratedQuery(query)) {
> while (it.hasNextRow()) {
> elementsList.add(it.nextRow());
> }
> }
> unfetchedObjects = elementsList.size();
