Error in converting JSF

Question

Error or Bug? Well I have an error appearing in the eclipse console, on the registration screen the form records perfectly, everything ok, but the console points:

java.lang.NumberFormatException: For input string: "Selecione"
    at java.lang.NumberFormatException.forInputString(Unknown Source)
    at br.com.bb.uds.rotinas.controller.converter.PessoaConverter.getAsObject(PessoaConverter.java:18)
    at com.sun.faces.renderkit.html_basic.HtmlBasicInputRenderer.getConvertedValue(HtmlBasicInputRenderer.java:171)
    at com.sun.faces.renderkit.html_basic.MenuRenderer.convertSelectOneValue(MenuRenderer.java:202)

My convert:

@FacesConverter(value = "pessoaConverter", forClass = Pessoa.class)
public class PessoaConverter implements Converter {

    @Override
    public Object getAsObject(FacesContext arg0, UIComponent arg1, String id) {
        try {
            PessoaServices pessoaServices = new PessoaServices();
            return pessoaServices.obterEntidade(Long.valueOf(id));
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    @Override
    public String getAsString(FacesContext arg0, UIComponent arg1, Object pessoa) {
        if (pessoa.toString().equals("-1")) {
            return null;
        }
        return ((Pessoa) pessoa).getId().toString();
    }

}

XHTML in which I use the convert:

<!-- RESPONSAVEL -->
<h:outputLabel for="responsavel" value="Responsável"
    styleClass="panelGridGerenciar" />
<p:selectOneMenu id="responsavel"
    value="#{rotinasBean.rotina.pessoaResponsavel}" required="true"
    requiredMessage="Selecione um responsável"
    converter="pessoaConverter">
    <p:ajax event="change" listener="#{rotinasBean.changeSubstituto}"
        update="substituto" />
    <f:selectItem itemLabel="Selecione" itemValue="-1" />
    <f:selectItems var="_responsavel"
        value="#{rotinasBean.selectResponsaveis}"
        itemValue="#{_responsavel}" itemLabel="#{_responsavel.nome}" />
</p:selectOneMenu>

The console points that line of error.

return pessoaServices.obterEntidade(Long.valueOf(id));

I don’t know if it’s really a mistake or a bug.

Answer 1

His method getAsObject is taking the string id, which in this case has the value "Select" and is trying to give a Long.valueof("Selecione") that causes a Exception. If you don’t want it to happen to Exception test if the value id is equal to "Select" and treat it as you wish, as long as the return is null.

If you are using this convert in a selectOneMenu, follow an example of code:

<p:selectOneMenu  value="#{bean.lista}" converter="pessoaConverter">
        <f:selectItem itemLabel="Selecione" itemValue="#{null}"/>
        <f:selectItems value="#{listapessoas}" var="p" itemValue="#{p}" itemLabel="#{p.nome}"/>
    </p:selectOneMenu>
