Filtered jsf outputtext

Question

I would like to know how to filter so that only the patents of vehicles that are available appear.

<p:column headerText="Patent car">
<h:outputText value="#{v.fkcar.patent}"/>   
</p:column>

In the database there is a table called State with 2 income

id_state 1 ---- name_state Available and id_state 2 ---- name_state Not available

What I need is that only the patents of the vehicles that have the State in Available are shown

The State table has its respective Bean

I hope you can help me: D

    </h:body> </html>

Here is the state bean code.

private int id_entregado;
private String nombre_entregado;


public EntregadoBean() {
}

public String crear(){
    Entregado e = new Entregado();
    e.setNombreEntregado(nombre_entregado);
    entregadoFacade.create(e);
    return "#";
}

public List<Entregado> getEntregado(){
    return entregadoFacade.findAll();
}

public EntregadoFacadeLocal getEntregadoFacade() {
    return entregadoFacade;
}

public void setEntregadoFacade(EntregadoFacadeLocal entregadoFacade) {
    this.entregadoFacade = entregadoFacade;
}

public int getId_entregado() {
    return id_entregado;
}

public void setId_entregado(int id_entregado) {
    this.id_entregado = id_entregado;
}

public String getNombre_entregado() {
    return nombre_entregado;
}

public void setNombre_entregado(String nombre_entregado) {
    this.nombre_entregado = nombre_entregado;
}


 }

For me your question is unclear. DataTable fetches from `alquilerBean`, but there is no code. It seems you have to filter inside `alquilerBean` like: `public Collection getAlquiler() { return alquielers.stream().filter(filterForAttribute).collect(Collectors.toList());` to only serve the vehicles to display. But as mentioned: make your question more clear. — ChristophS, Jul 09 '18 at 06:13
@ChristophS: Don't do that in the getter. Or do it lazy http://stackoverflow.com/questions/2090033/why-jsf-calls-getters-multiple-times — Kukeltje, Jul 09 '18 at 08:15
Datatable complete is https://github.com/basnunez/Arrienda_Auto — Yerko Lizama Hermosilla, Jul 09 '18 at 08:28
@Kukeltje: I know about multiple executions of getters ... but you can do as long as you collect data only once. Same is done in your link (`if (someProperty == null) {...}`) — ChristophS, Jul 09 '18 at 09:07
@YerkoLizamaHermosilla: pls understand that I don't want to examine your project. Some hints: don't use constructor to initialize bean member variables (AlquilerBean.class), read about PostConstruct annotation. Maybe use an dedicated getter method to only serve the data you want do display (e.g. `getByState(stateAvailable)', read link by Kukeltje why bean gettery may perform bad. Here is an exaple for PostConstruct and dataTable, modify for your needs: https://stackoverflow.com/questions/5765853/how-and-when-should-i-load-the-model-from-database-for-hdatatable — ChristophS, Jul 09 '18 at 09:17
@ChristophS: yes, that is why I mentioned 'lazy'... in my comment too. ;-) — Kukeltje, Jul 09 '18 at 09:53
