Pessoal, venho novamente aqui pedir ajuda de vocês, pois estou criando componentes dinamicos, porem estou com problema no SelectOneMenu e SelectItem, é o seguinte tenho o seguinte metodo
ATRIBUTOS
    private Class classePessoa;
    private Pessoa pessoa;
    private HtmlForm formulario;
    private HtmlPanelGrid painel;
    private HtmlPanelGrid painelPrincipal;
    private List<String> pessoas;
    private List<String> pessoasSelecionadas;
    private List<String> operadores;
    private List<SelectItem> operadoresSelectItem;
    private List<String> operadoresSelecionados;
    private List<String> valoresFiltro;
    private String filtroTeste;
    private HtmlInputSecret itxOperador;
GETTERS E SETTERS
METODO
private void criarComponentes() {
        FacesContext context = FacesContext.getCurrentInstance();
        ELContext elContext = context.getELContext();
        Application app = context.getApplication();
        ExpressionFactory expressionFactory = app.getExpressionFactory();
        this.setPainel(new HtmlPanelGrid());
        this.getPainel().setColumns(2);
        HtmlOutputText hotTitulo = (HtmlOutputText) FacesContext.getCurrentInstance().getApplication().createComponent(HtmlOutputText.COMPONENT_TYPE);
        hotTitulo.setValue("Configuração do Relatório de Pessoas");
        Integer posicao = 0;
        this.setFormulario(new HtmlForm());
        for (Field field : this.getClassePessoa().getDeclaredFields()) {
            HtmlSelectOneMenu somOperadores = new HtmlSelectOneMenu();
            somOperadores.setId("som" + posicao);
            UISelectItems sim = new UISelectItems();
            sim.setId("sim" + posicao);
            ValueExpression veSim = expressionFactory.createValueExpression(elContext, "#{mbPessoa.operadoresSelectItem}", List.class);
            sim.setValueExpression("value", veSim);
            somOperadores.getChildren().add(sim);
            this.getOperadoresSelecionados().add(new String());
            ValueExpression veSom = expressionFactory.createValueExpression(elContext, "#{mbPessoa.operadoresSelecionados.get(" + posicao + ")}", String.class);
            somOperadores.setValueExpression("value", veSom);
            HtmlInputText itxOperador = new HtmlInputText();
            itxOperador.setId("itx" + posicao);
            this.getValoresFiltro().add(new String());
            ValueExpression veItx = expressionFactory.createValueExpression(elContext, "#{mbPessoa.valoresFiltro.get(" + posicao + ")}", String.class);
            this.getPainel().getChildren().add(somOperadores);
            this.getPainel().getChildren().add(itxOperador);
            posicao = posicao + 1;
        }
        this.getFormulario().getChildren().add(this.getPainel());
    }
e tenho a seguinte JSF

    </h:body>

Quando eu rodo minha aplicação funciona certinho, cria os SelectOneMenu com os items e tals, o problema é que quando eu clico no botão “Metodo” chama um metodo no meu mb que serve somente para teste, testa se esta fazendo submit e tals, porem ele nem chega chamar este metodo gera a exeção javax.el.PropertyNotWritableException: Illegal Syntax for Set Operation na hora que eu clico.
