I have a problem to load the selected value in <f:selectItem> by the user When render gets that way:

<option value="320">Coordenador Desenvolvimento</option>

I wanted the attribute to be set selected="selected"

Follow my xhtml:

<div class="span3">
    <h:selectOneMenu id="txttecnicosselecionaveis" required="true" 
                     requiredMessage="Selecione o tecnico responsável pelo cliente" 
                     binding="#{cadastradorCliente.txtTecnicosSelecionaveis}" disabled="#{cadastradorCliente.desabilitarCampos}" styleClass="span12">
        <f:selectItems value="#{cadastradorCliente.tecnicosSelecionaveis}" 
                       itemLabel="#{cliente.tecnico.nome}" itemValue="#{cliente.tecnico.id}"/>
    </h:selectOneMenu>
</div>

My MB where I recover the data

public String actSelecionarTabela()
{
    FacesContext context = FacesContext.getCurrentInstance();
    HttpSession sessao = (HttpSession) context.getExternalContext().getSession(true);

    if (sessao != null) 
    {
        sessao = (HttpSession) context.getExternalContext().getSession(true);
        sessao.setAttribute("cliente", cliente);
    }

    txtCnpj.setValue(cliente.getCnpj());
    txtRazaoSocial.setValue(cliente.getRazaoSocial());
    txtNomeFantasia.setValue(cliente.getNomeFantasia());
    txtInscricaoEstadual.setValue(cliente.getInscricaoEstadual());
    txtSite.setValue(cliente.getSite());

    txtEndereco.setValue(cliente.getEndereco().getDescricao());
    txtResponsavel.setValue(cliente.getResponsavel().getNome());
    txtTelefone.setValue(cliente.getResponsavel().getContato().getTelefone());
    txtEmail.setValue(cliente.getResponsavel().getContato().getEmail());
    txtCemail.setValue(cliente.getResponsavel().getContato().getCemail());
    txtAtivo.setValue(cliente.isAtivo());       
    txtTecnicosSelecionaveis.setValue(cliente.getTecnico().getCodigo());
    txtGerentesSelecionaveis.setValue(cliente.getGerente().getCodigo());

When I return the data saved on the screen back so my selectItem inserir a descrição da imagem aqui

I would like to return already loaded the values that were selected the first time inserir a descrição da imagem aqui

Here is the result of database saved data inserir a descrição da imagem aqui

I’ve tried several ways and I can’t fix it, anyone has any idea?

java jsf

  • "i wanted it to be set the attribute Selected="Selected" - I didn’t understand.

  • Example I have already registered in database with the id of selectItem, however I want to load on the screen back the data for the user to be able to edit, I can recover on screen all the data of the register less my selected item

    How about posting a property to the bean that returns the selected item, and then setting the component’s "value" attribute pointing to this property <h:selectOneMenu value="#{cadastradorCliente.tecnicoSelecionado}">?

  • @Caffé my returns to xhtml are returning the correct value, the problem is when I click to select on the screen and trigger my actionListener "txtTecnicosSelectible.setValue(client.getTecnico().getCodigo());" It brings me the code that was saved it just doesn’t click on the screen :(

    I imagine that the problem is not only display, but that you also could not yet save in the bank a selected item on the page (inserted in the bank by another means). Right?

  • With you, I save the id and name of the selected technician and manager , I can also change this data through the application. It just doesn’t display :(

  • "the problem is when I click to select on the screen and fires my actionListener..." Well, I really couldn’t understand the problem. Good luck there!

Missing include the property value in the selectOneMenu.

For example, if your Managed bean owns the property tecnicoResponsavel indicating the previously selected technician you can do something like this:

<h:selectOneMenu id="txttecnicosselecionaveis" required="true" 
                     requiredMessage="Selecione o tecnico responsável pelo cliente" 
                     binding="#{cadastradorCliente.txtTecnicosSelecionaveis}"
                     disabled="#{cadastradorCliente.desabilitarCampos}" 
                     <!-- Carrega id do tecnico responsavel -->
                     value="#{cadastradorCliente.tecnicoResponsavel.id}"
                     styleClass="span12">

In order for a certain item to be preselected value of selectOneMenu should match the itemValue of selectItems (in that case, #{cliente.tecnico.id})

Sources:

  1. Soen - JSF: default Selection for <f:selectItem> Within <h:selectOneMenu>
  2. Soen - JSF f:selectItems set item Selected.

  • was that same guy, I’m still crawling in development, thank you very much.

  • Whoa, thank the @Caffè, only saw his comment now.

  • @Caffé thanks a lot for the help I ended up forgetting you!.

  • @What Anthony meant was that this same suggestion I had already made in the comments, right at the beginning of our conversation. Success there!

  • @Caffé I’m sorry, I had not understood your suggestion, thank you very much.

  • @Caffe, can I have a question? yesterday I thought I had solved the problem I created a property(String) in my MB that receives the selected technician that comes from the bank after recording, I have already performed a debug and the variables are being filled, but at the time of rendering it does not appear in the Selectonemenu.
