java.lang.ClassCastException: java.lang.String cannot be cast to javax.faces.model.SelectItem

Question

I'm trying to get the itemValue from a oneSelectMenu but this exception has returned. Could anyone help me?

<p:outputLabel for="tipo" value="Tipo "/>
                    <p:selectOneMenu id="tipo" value="#{pessoaBean.pessoa.tipo}">
                        <f:selectItem itemLabel="Cliente" itemValue="Cliente"/>
                        <f:selectItem itemLabel="Funcionário" itemValue="Funcionário"/>
                    </p:selectOneMenu>

help with what? did you read the error message? you are trying to cast a String to a SelectItem. since there is no is-a relationship between the two, that's not possible — Stultuske, Nov 06 '17 at 17:24
As already mentioned by others, you should post the content of `pessoa` and `pessoaBean` so that someone might help you. — ujulu, Nov 06 '17 at 20:41

Maybe you have to implement a javax.faces.Converter and add attribute converter="..." to p:selectOneMenu

see for example How to inject @EJB, @PersistenceContext, @Inject, @Autowired, etc in @FacesConverter?
