Estou com um problema na validação com Vraptor 3, no caso, é simplesmente um cadastro de usuário que pode ter uma ou muitas regras relacionadas.
Meu controller está assim:
[code]@Path("/user/insert")
public void form()
{
result.include(“roleList”, this.roleDao.listAll());
}
@Path("/user/edit")
public User form(Long user_pk)
{
result.include(“roleList”, this.roleDao.listAll());
return this.dao.find(user_pk);
}
@Post
public void save(User user, String confirmation)
{
result.include(“roleList”, this.roleDao.listAll());
if (user.getLogin().isEmpty())
validator.add(new ValidationMessage(“users.login_empty”, “error”));
if (user.getRole() == null)
validator.add(new ValidationMessage(“users.roles_empty”, “error”));
validator.onErrorUse(Results.page()).of(UserController.class).form();
if (user.getUser_pk() == null)
this.dao.insert(user);
else
this.dao.update(user);
}[/code]
Observe que tenho que verificar se alguma regra foi escolhida e é aí que está o problema. Meu JSP está assim:
[code]
<c:forEach var=“r” items="${roleList}" varStatus=“s”>
<c:set var=“checked” value=“false” />
<c:forEach var=“u” items="${user.role}">
<c:if test="${r.role_pk == u.role_pk}">
<c:set var=“checked” value=“true” />
</c:if>
</c:forEach>
<input type=“checkbox” name=“user.role[${s.index}].role_pk” value="${r.role_pk}" <c:if test="${checked}">checked</c:if> /> ${r.name} - ${r.description}
</c:forEach>[/code]
Algém tem alguma sugestão para resolver esse problema? Estou parado nesse ponto há dias e estou sem idéias. O erro é esse:
