Bom dia galera tudo bem?
É o seguinte, no sistema que uso criei uma tela onde tem o seguinte componente:
<t:div>
<h:panelGrid columns="1" id="campos">
<h:outputLabel value="Selecione o tipo de Rota as ser usada"/>
<h:selectOneRadio binding="#{tipoRota.selecao}">
<f:selectItem itemValue="M" itemLabel="Minhas Rotas"/>
<f:selectItem itemValue="C" itemLabel="Criar Rotas"/>
<a4j:support event="onclick" action="#{tipoRota.proximo}" />
</h:selectOneRadio>
</h:panelGrid>
</t:div>public class TipoRota extends TipoRotaForm {
public String proximo(){
String retorno = "";
if(selecao.getValue() == null || ((String)selecao.getValue()).equals("")) {
MessageHelper.addMessage("Selecione uma opção para passar para a proxima tela!", 2);
return null;
} else {
if( ((String) selecao.getValue()).equals("M") ){
JsfHelper.setSessionAttribute( "tipoEscolhido", (String)selecao.getValue());
retorno = "novaRota";
} else{
JsfHelper.setSessionAttribute( "tipoEscolhido", (String)selecao.getValue());
retorno = "rotaFinaliza";
}
}
return retorno;
}public class TipoRotaForm {
public HtmlSelectOneRadio selecao;
public TipoRotaForm() {
selecao = new HtmlSelectOneRadio();
}
public HtmlSelectOneRadio getSelecao() {
return selecao;
}
public void setSelecao(HtmlSelectOneRadio selecao) {
this.selecao = selecao;
}Quando eu vou acessando na sequencia as telas ela funciona perfeitamente, mas quando eu clico no botão voltar está gerando a seguinte exception:

Desde já agradeço a atenção.
