Description

The current process for pagination uses direct method for gathering data. Without any checks, validations and convertations. 

public class DataContext extends BaseContext{
...
public ResultIterator performIteratedQuery(Query query)
}

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();
}

After applying this PR we need to redirect pagination flow to the

public class DataContext extends BaseContext{
...
public <T> ResultIterator<T> iterator(final Select<T> query)  
}
