primefaces not show dataTable values with lazyModel - jsf

Question

I'm starting with primefaces and I try use LazyModel in p:dataTable.
I already implemented the LazyModel, bean and jsf. The call's to bean and model occur's correctly and my bean return a list with elements, but my jsf show nothing.
Please, somebody know whats happen?
Bellow is my code:
JSF:
<ui:composition template="./newTemplate.xhtml">
<ui:define name="content">
content
<h:form>
<p:panel id="formFiltro">
<p:messages id="messages"/>
<h:panelGrid>
<h:outputLabel for="fieldConta" value="Número da Conta:"/>
<p:inputText id="fieldConta" value="#{log.nrConta}" label="Número da Conta">
<f:convertNumber integerOnly="true" type="number"/>
</p:inputText>
<!--<p:message for="fieldConta" />-->
<h:outputLabel for="fieldAgencia" value="Código da Agência:"/>
<p:inputText id="fieldAgencia" value="#{log.nrAgencia}" label="Código da Agência">
<f:convertNumber integerOnly="true" type="number"/>
</p:inputText>
<!--<p:message for="fieldAgencia" />-->
<center>
<p:commandButton ajax="false" value="Pesquisar" action="#{log.search}" />
</center>
</h:panelGrid>
</p:panel>
<p:dataTable var="l" value="#{log.lazyLogModel}" paginator="true" rows="5"
paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
rowsPerPageTemplate="5,10,15" id="logTable" lazy="true">
<p:column headerText="ID">
<h:outputText value="#{l.logId}" />
</p:column>
<p:column headerText="Agência">
<h:outputText value="#{l.logAgencia}" />
</p:column>
<p:column headerText="Conta">
<h:outputText value="#{l.logConta}" />
</p:column>
<p:column headerText="SO">
<h:outputText value="#{l.logSo}" />
</p:column>
<p:column headerText="Plugin">
<h:outputText value="#{l.logVersaoPlugin}" />
</p:column>
<p:column headerText="Tam F10">
<h:outputText value="#{l.logTamF10}" />
</p:column>
</p:dataTable>
</h:form>
</ui:define>
</ui:composition>
My bean:
#ManagedBean(name="log")
#RequestScoped
public class consultaJsf implements Serializable {
private static final long serialVersionUID = 1L;
/**
* Creates a new instance of consultaJsf
*/
private List<TbLogLog> listaLog;
private LazyLogModel lazyLogModel;
private int nrConta;
private int nrAgencia;
public consultaJsf() {
try{
//this.listaLog = new ConsultarDados().getListLogAll();
}catch(Exception e){
e.printStackTrace();
}
}
#PostConstruct
public void init()
{
this.lazyLogModel = new LazyLogModel();
}
public List<TbLogLog> getListaLog()
{
return listaLog;
}
public int getNrConta()
{
return nrConta;
}
public void setNrConta(int nrConta)
{
this.nrConta = nrConta;
}
public int getNrAgencia()
{
return nrAgencia;
}
public void setNrAgencia(int nrAgencia)
{
this.nrAgencia = nrAgencia;
}
public LazyLogModel getLazyLogModel()
{
return this.lazyLogModel;
}
public String search() throws Exception
{
if(nrConta != 0)
this.listaLog = new ConsultarDados().getListLogByConta(nrConta);
else if(nrAgencia != 0)
this.listaLog = new ConsultarDados().getListLogByAgencia(nrAgencia);
return null;
}
}
My LazyModel:
public class LazyLogModel extends LazyDataModel<TbLogLog> {
private String nrConta;
private String cdAgencia;
#Override
public List<TbLogLog> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String, String> filters) {
List<TbLogLog> listaLog = null;
try{
listaLog = new ConsultarDados().getListLogAll(first, pageSize);
}catch(Exception e){
return null;
}
return listaLog;
}
/**
* #return the nrConta
*/
public String getNrConta() {
return nrConta;
}
/**
* #param nrConta the nrConta to set
*/
public void setNrConta(String nrConta) {
this.nrConta = nrConta;
}
/**
* #return the cdAgencia
*/
public String getCdAgencia() {
return cdAgencia;
}
/**
* #param cdAgencia the cdAgencia to set
*/
public void setCdAgencia(String cdAgencia) {
this.cdAgencia = cdAgencia;
}
}
Consult Method called by LazyModel:
private List<TbLogLog> getListLog(String hql, int firstResult, int sizePage) throws Exception {
List resultList = null;
try {
Session session = HubernateUtil.getSessionFactory().openSession();
if ((hql == null) || (hql.trim().length() == 0)) {
hql = QUERY_PESQUISAR_TODOS;
}
Query q = session.createQuery(hql);
if(firstResult > 0 )
q.setFirstResult(firstResult);
if(sizePage > 0)
q.setMaxResults(sizePage);
resultList = q.list();
} catch (HibernateException he) {
he.printStackTrace();
}
return resultList;
}
Everything work's fine, but my jsf don't show any result.
Thanks in advance.

Remove the init() in consultaJsf Class and update the getLazyLogModel() as follows
#ManagedBean(name="log")
#RequestScoped
public class consultaJsf implements Serializable {
private static final long serialVersionUID = 1L;
/**
* Creates a new instance of consultaJsf
*/
private List<TbLogLog> listaLog;
private LazyLogModel<TbLogLog> lazyLogModel;
private int nrConta;
private int nrAgencia;
public consultaJsf() {
try{
//this.listaLog = new ConsultarDados().getListLogAll();
}catch(Exception e){
e.printStackTrace();
}
}
public List<TbLogLog> getListaLog()
{
return listaLog;
}
public int getNrConta()
{
return nrConta;
}
public void setNrConta(int nrConta)
{
this.nrConta = nrConta;
}
public int getNrAgencia()
{
return nrAgencia;
}
public void setNrAgencia(int nrAgencia)
{
this.nrAgencia = nrAgencia;
}
public LazyLogModel<TbLogLog> getLazyLogModel()
{
if (lazyLogModel== null) {
lazyLogModel= new LazyDataModel<TbLogLog>() {
#Override
public List<TbLogLog> load(int first, int pageSize, String sortField,
SortOrder sortOrder, Map<String, String> filters) {
List<TbLogLog> listaLog = null;
try{
listaLog = new ConsultarDados().getListLogAll(first, pageSize);
}catch(Exception e){
return null;
}
return listaLog;
}
};
}
return listaLog;
}
public String search() throws Exception
{
if(nrConta != 0)
this.listaLog = new ConsultarDados().getListLogByConta(nrConta);
else if(nrAgencia != 0)
this.listaLog = new ConsultarDados().getListLogByAgencia(nrAgencia);
return null;
}
}
