acho q sua descrição esta nula por isso não salva no banco.

att,

é ttipo.descricao msm? com 2 t ?

att,

então o que ocorre é que quando ocorre o submit chega tudo null, ai dei uma analisada no debug e vi isso:

17:53:26,421 DEBUG [OgnlParametersProvider] Applying ipo.descricao with [fdsfsd] 
17:53:26,421 DEBUG [OgnlFacade          ] cant find property for expression ipo.descricao ignoring

e coloquei ttipo, ele corta a primeira letra do mesmo jeito porem não funciona, esse projeto foi criado em cima do blank project.

Listando o banco de dados ele ta, pois já testei.

Nas entidades preciso anotar algo mais alem do JPA ?

jhonevitor

olha, vc etá recebendo um objeto tipo com o nome de ‘t’ no seu metodo e no seu .jsp vc está enviando um objeto ‘ttipo’ para o vraptor converter pra vc os tipos do metodo e do jsp tem que ter o mesmo nome ou ‘t’ ou ‘ttipo’. fui claro?

Edit: Agora que eu entendi, funcionou, obrigado !!!

Lucas_Cavalcanti

mas o parâmetro do método do controller se chama tipo?

J
jhonevitor

bom, veja só

<body>  
    <form action="novo">  
        <input type="text" name="ttipo.descricao"> <input  
            type="submit" value="Salvar">  
    </form>  
</body>
aqui seu form action nao devia ser 
<form action="/novo">

e no seu metodo

public void novo(Tipo t) {  
        try {  
            dao.add(t);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }
onde tem "Tipo t" vc deve receber
public void novo(Tipo tipo) {
praficar com o mesmo nome do .jsp ou então no jsp vc poe assim 
<input type="text" name="t.descricao"> <input  
            type="submit" value="Salvar">  
    </form>
pra que o vraptor possa encontrar os parametros correspondentes e converter

Então lucas agora sim ! ele estava assim:

public void novo(Tipo t) {  
        try {  
            dao.add(t);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }

ficou assim

public void novo(Tipo tipo) {  
        try {  
            dao.add(tipo);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }

funcionou !
