Problema em rich:dataTable

Front-end
#1

Olá, caros.
A dúvida é algo que era para parecer simples.
Implementei uma paginação à partir do blog de Marcus mazzo.
Funcionou muito bem, porém, ao executar o componente pela primeira vez os dados são carregados e há de fato uma paginação, porém, ao clicar sobre o link da página pela segunda vez, o layout simplesmente se perde, como se não houvesse Css definido, as cores somes e as divisões da tabela, como se não houvesse implementado, de fato uma suite de componentes.

Classe para paginar:

package br.com.agets.paginator;

import java.io.Serializable;
import java.util.List;

import javax.faces.model.DataModel;

@SuppressWarnings("rawtypes")
public class PagedDataModel extends DataModel implements Serializable {
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	   private int rowIndex = -1;  
	    private int totalNumRows;  
	    private int pageSize;  
	      
	    private List<?> list;  
	  
	    public PagedDataModel() {  
	        super();  
	    }  
	  
	    public PagedDataModel(List<?> list, int totalNumRows) {  
	        super();  
	        setWrappedData(list);  
	        this.totalNumRows = totalNumRows;  
	        this.pageSize = list.size();  
	    }  
	  
	    public PagedDataModel(List<?> list, int totalNumRows, int pageSize) {  
	        super();  
	        setWrappedData(list);  
	        this.totalNumRows = totalNumRows;  
	        this.pageSize = pageSize;  
	    }  
	  
	    @Override  
	    public boolean isRowAvailable() {  
	        if (list == null)  
	            return false;  
	  
	        int rowIndex = getRowIndex();  
	        if (rowIndex >= 0 && rowIndex < list.size())  
	            return true;  
	        else  
	            return false;  
	    }  
	  
	    @Override  
	    public int getRowCount() {  
	        return totalNumRows;  
	    }  
	  
	    @Override  
	    public Object getRowData() {  
	        if (list == null)  
	            return null;  
	        else if (!isRowAvailable())  
	            throw new IllegalArgumentException();  
	        else {  
	            int dataIndex = getRowIndex();  
	            return list.get(dataIndex);  
	        }  
	    }  
	  
	    @Override  
	    public int getRowIndex() {  
	        try {  
	            return (rowIndex % pageSize);  
	        } catch (ArithmeticException e) {  
	            return 0;  
	        }  
	    }  
	  
	    @Override  
	    public void setRowIndex(int rowIndex) {  
	        this.rowIndex = rowIndex;  
	    }  
	  
	    @Override  
	    public Object getWrappedData() {  
	        return list;  
	    }  
	  
	    @Override  
	    public void setWrappedData(Object list) {  
	        this.list = (List<?>) list;  
	    }  
	}

Métodos usados para paginação com Hibernate.


	@SuppressWarnings("unchecked")
	public List<T> listarTodos(Integer startPage, Integer maxPage, List<Criterion> restricoes, List<Projection> projecoes, List<Order> ordenacao) {
		Criteria criteria = this.session.createCriteria(this.persistentClass);

		List<T> list = new ArrayList<T>();
		if (restricoes != null) {
			for (Criterion r : restricoes) {
				criteria.add(r);
			}
		}
		if (projecoes != null) {
			for (Projection p : projecoes) {
				criteria.setProjection(p);
			}
		}
		if (ordenacao != null) {
			for (Order order : ordenacao) {
				criteria.addOrder(order);
			}
		}
		criteria.setFirstResult(startPage);
		criteria.setMaxResults(maxPage);
		list = criteria.list();

		for (T t : list) {

			for (Method method : t.getClass().getMethods()) {

				if (method.getName().indexOf("get") > -1) {

					Object obj;
					try {
						obj = method.invoke(t);

						if (obj instanceof java.util.Collection) {

							for (T lista : (List<T>) obj) {

								Hibernate.initialize(lista);

							}
						}
					} catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException e) {
						e.printStackTrace();
					}
				}

			}

		}
		return list;
	}

	public Integer count(List<Criterion> restricoes) {
		Number size = 0;
		Criteria c = this.session.createCriteria(this.persistentClass);
		if (restricoes != null) {
			for (Criterion criterion : restricoes) {
				c.add(criterion);
			}
		}
		size = ((Long) c.setProjection(Projections.rowCount()).uniqueResult());
		return size.intValue();

	}

Implementação da paginação mo MBean



	private DataModel dataModel;
	private UIDataTable uiDataTable;


//GETS/SETS destes valores acima.


	@SuppressWarnings("rawtypes")
	public DataModel getDataModel() {
		int totalListSize = new AtendimentoService().count();
		List<Atendimento> pagedList = new AtendimentoService().listarTodos(getUiDataTable().getFirst(), getUiDataTable().getRows());
		dataModel = new PagedDataModel(pagedList, totalListSize);
		return dataModel;

	}
