Tenta isso.

GUJ Hacker Membro desde: 08/07/2007 00:08:14 Mensagens: 6396 Offline

a tag <select> não tem o atributo value, ele está nas options...

no controller vc está recebendo um parâmetro chamado tipoVisita?

JavaChild Membro desde: 30/10/2009 19:13:03 Mensagens: 148 Offline

no controler esta assim

preciso receber o objeto para adicionar a uma visita

No meu projeto eu passo só o ID e depois eu faço uma consulta e trago o objeto completo...

JSP:

Controller:

dá uma olhada neste tópico também:

-Edit-
o "name" do seu select tem q ser igual ao nome do parametro que vc recebe, exemplo:

Mais não tem como recuperar o objeto inteiro para evitar realizar uma consulta no banco?

GUJ Hacker Membro desde: 08/07/2007 00:08:14 Mensagens: 6396 Offline

se o nome do parâmetro é "tipo", o name do select tb tem que ser "tipo"

tipoVisita não é um enum?

JavaChild Membro desde: 30/10/2009 19:13:03 Mensagens: 148 Offline

não, TipoVisita é uma Classe que

os tipos são recuperados no banco de dados e populam o select

GUJ Hacker Membro desde: 08/07/2007 00:08:14 Mensagens: 6396 Offline

então o select tem que se chamar tipo.id e o value das options também tem que ser o id do tipo...

JavaChild Membro desde: 30/10/2009 19:13:03 Mensagens: 148 Offline

Por exemplo:
eu tenho a o seguinte codigo

public class Visita implements Serializable {

@Id
    @AttributeOverrides({
        @AttributeOverride(name="visID", column=@Column(name="vis_id", nullable=false, precision=10, scale=0)),
        @AttributeOverride(name="tecID", column=@Column(name="vis_tec_codext", nullable=false, precision=10, scale=0)),
        @AttributeOverride(name="visitaSequencia", column=@Column(name="vis_sequencia", nullable=false, precision=10, scale=0))
    })
    @Column(name="vis_id", nullable=false)
    private VisitaID id;
     .
     .
     .

@ManyToOne
    @JoinColumns({
       @JoinColumn(name="vis_cli_codigo", referencedColumnName="cli_codext", insertable=true, updatable=true),
       @JoinColumn(name="vis_cli_filial", referencedColumnName="cli_fili", insertable=true, updatable=true),
       @JoinColumn(name="vis_cli_regiao", referencedColumnName="cli_regi", insertable=true, updatable=true)
    })
    @Fetch(FetchMode.JOIN)
    @Cascade(CascadeType.SAVE_UPDATE)
    private Cliente cliente;

queria saber se consigo na minha jsp adicionar o o objeto cliente que esta na minha seção a visita
tipo

onde cliente foi enviado pelo controller
ou eu tenho que fazer

pois acho que do primeiro jeito seria mais facil, como se fosse um visita.setCliente(cliente);

GUJ Hacker Membro desde: 08/07/2007 00:08:14 Mensagens: 6396 Offline

vc precisa passar pelo id mesmo...

lembre-se que vc está gerando um HTML, e no html não existe uma representação de Cliente...

passando o id, o hibernate já consegue se virar
