I'm having a problem loading the selected value into <f:selectItem> by the user when rendering looks like this:

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

I wanted to set the attribute 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 retrieve 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 it returns my selectItem

The value property in selectOneMenu is missing.

For example, if your managed bean has the tecnicoResponsavel property 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">

For a given item to be pre-selected, the value of the selectOneMenu must hit with the itemValue of the selectItems (in this case, #{cliente.tecnico.id} )
