I have this xhtml code:
<div class="row">
<div class="col-lg-5 col-md-5 col-sm-12 col-xs-12">
<div class="input-group">
<h:inputText p:placeholder="Nro Documento" class="form-control" value="#{BeanPersonal.paramNroDocSearch}" id="paramNroDoc" type="text"/>
</div>
</div>
<div class="col-lg-1 col-md-1 col-sm-12 col-xs-12">
<div class="input-group">
<h:commandLink id="searchButton" value="" >
<f:ajax event="click" listener="#{BeanPersonal.buscarPersonasN()}" render="tablaDatos" execute="paramNroDoc"/>
<i class="fa fa-search fa-2x"></i>
</h:commandLink>
</div>
</div>
</div>
<h:panelGroup id="tablaDatos">
<div class="row">
<h:panelGroup rendered="#{BeanPersonal.personasN.isEmpty() eq false}">
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
<div class="table-responsive">
<h:dataTable id="personasN" styleClass="table table-bordered" value="#{BeanPersonal.personasN}" var="perN" >
<h:column>
<f:facet name="header">Apellido y Nombre</f:facet>
<h:outputText id="nombreCompleto" value="#{perN.nombreNCompleto}" />
</h:column>
<h:column>
<f:facet name="header">Nro. Documento</f:facet>
<h:outputText id="doc" value="#{perN.documentoNro}" />
</h:column>
<h:column>
<f:facet name="header">Sexo</f:facet>
<h:panelGroup rendered="#{perN.sexo eq 'M'}">
<h:outputText value="Masculino" />
</h:panelGroup>
<h:panelGroup rendered="#{perN.sexo eq 'F'}">
<h:outputText value="Femenino" />
</h:panelGroup>
</h:column>
<h:column>
<h:commandButton class="btn btn-info" value="Seleccionar" type="button" >
<f:ajax event="click" listener="#{BeanPersonal.seleccionPersonaN(perN)}" render="datos" onevent="defaultTab"></f:ajax>
</h:commandButton>
</h:column>
</h:dataTable>
</div>
</div>
</h:panelGroup>
<h:panelGroup >
<h:panelGroup layout="block" rendered="#{Bean.personasN.isEmpty() eq true}">
<div class="row">
<div class="col-lg-3 col-sm-3 col-lg-offset-3 col-sm-offset-3 col-xs-12">
<h2>
<span class="label label-danger">No se ha encontrado la persona</span>
</h2>
</div>
</div>
<div class="col-lg-3 col-md-3 col-sm-12 col-xs-12">
<div class="input-group">
<h:commandButton class="btn btn-info" value="Dar de Alta Nuevo" type="button" >
<f:ajax event="click" listener="#{Bean.nuevaPersona()}" render="datos" onevent="defaultTab"/>
</h:commandButton>
</div>
</div>
</h:panelGroup>
</h:panelGroup>
</div>
</h:panelGroup>
And in the BeanPersonal the following method:
public void buscarPersonasN()
{
personasN = new ArrayList<PersonasN>();
Session sessionN = null;
try{
paramNroDocSearch = paramNroDocSearch.trim();
sessionN = DBUtil.crearSesion();
personasN = sessionN.createQuery("select p from PersonasN as p where p.documentoNro = :documentoNro")
.setParameter("documentoNro", paramNroDocSearch)
.list();
if(personasN == null){
personasN = new ArrayList<PersonasN>();
}
}catch(Exception e){
e.printStackTrace();
}finally{
if(sessionN != null)
sessionN.close();
}
}
The idea is basically to find a person in a database and add them in a list to show in a h: datatable so that it can be selected.
When I execute the code, there are times when it works well, but sometimes where I miss the following error:

It gives me the error and I can not find a logic for it because it's long, and it does not show me any line of the code above. The error is generated when I press the h: commandLink.
