Weird NPE when trying to grant permission
Hi everyone,
I'm using Seam 2.1.0.SP1 and trying to make a simple test to exercite seam's permission stores but I'm facing a strange problem when invoking grantPermission() method of PermissionManager. It all starts from a simple call to my PermissionAction.grantPermission(User) method:
<h:dataTable id="users" value="#{users}" var="user" rendered="#{users.rowCount>0}">
...
<h:column id="column3" rendered="#{s:hasRole('admin')}">
<f:facet id="ActionFacet" name="header">Perfis</f:facet>
<s:link id="viewRoles" value="Alterar" action="#{roleAction.selectUser(user)}" />
<s:link id="ativar" value="Ativar" rendered="#{s:hasPermission(user,'mudar')}" action="#{permissionAction.grantPermission(user)}" />
...Then in the PermissionAction:
@Name("permissionAction")
public class PermissionAction {
@In
private PermissionManager permissionManager;
@In
private Identity identity;
public void grantPermission(UserAccount user) {
Permission p = new Permission(user, "mudar", identity.getPrincipal());
permissionManager.grantPermission(p);
}
...I debugged and checked that none of the paremeters of the Permission p are null.
While executing the permissionManager.grantPermission(p); this shows up in the browser window(not in the appserver console):
Exception during request processing: Caused by javax.el.ELException with message: "java.lang.RuntimeException: Could not grant permission"

I've did everything to try to mimic the SeamSpace example but I couldn't solve this error.
My UserAccount class (The target of the permission) is :
@Entity
@Table(name = "user_account")
@NamedNativeQueries( { @NamedNativeQuery(name = IUser.USER_BY_STORED_PROCEDURE, resultClass = UserAccount.class, query = "{ call SELECT_USERS(?, ?, ?) }", hints = {
@QueryHint(name = "org.hibernate.callable", value = "true"),
@QueryHint(name = "org.hibernate.readOnly", value = "true") }) })
@NamedQueries( {
@NamedQuery(name = IUser.USER_VALIDATE, query = "select u from UserAccount u where u.login = :login and u.password = :password"),
@NamedQuery(name = IUser.USER_BY_LOGIN, query = "select u from UserAccount u where u.login=:login"),
@NamedQuery(name = IUser.USER_BY_NAME, query = "select u from UserAccount u where lower(u.userInfo.name) like lower(:name) order by u.userInfo.name") })
@Permissions({
@Permission(action = "mudar"),
@Permission(action = "desmudar")
})
//@Identifier(value=TestIdentifier.class)
@Identifier(value=EntityIdentifierStrategy.class)
@Name("userAccount")
public class UserAccount implements IUser {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private Integer id;
@Column(name = "login")
private String login;
@Column(name = "password")
private String password;
@ManyToMany(targetEntity = Role.class, cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"), inverseJoinColumns = @JoinColumn(name = "role_id"))
private Set<Role> roles;
@OneToOne(targetEntity=UserInfo.class)
@JoinColumn(name = "userinfoId")
private UserInfo userInfo;
public UserAccount(){
this.userInfo = new UserInfo();
}
public UserInfo getUserInfo() {
return userInfo;
}
public void setUserInfo(UserInfo userInfo) {
this.userInfo = userInfo;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
@NotNull
@UserPrincipal
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
@NotNull
@UserPassword(hash = "none")
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@UserRoles
public Set<Role> getRoles() {
return roles;
}
public void setRoles(Set<Role> roles) {
this.roles = roles;
}
@Transient
public Set<Role> getRoles(ISystem system) {
Set<Role> systemRoles = new HashSet<Role>();
for (Role role : roles) {
if (role.getSystem().equals(system)) {
systemRoles.add(role);
}
}
return systemRoles;
}
@Override
public int hashCode() {
int hash = 0;
hash += (id != null ? id.hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are
// not set
if (!(object instanceof UserAccount)) {
return false;
}
UserAccount other = (UserAccount) object;
if ((this.id == null && other.id != null)
|| (this.id != null && !this.id.equals(other.id))) {
return false;
}
return true;
}
}
I've also tryed without any @Identifier annotations and with my custom identifier strategy TestIdentifier:
public class TestIdentifier implements IdentifierStrategy {
public boolean canIdentify(Class arg0) {
return arg0.equals(UserAccount.class);
}
public String getIdentifier(Object arg0) {
return "user"+((UserAccount) arg0).getId();
}
}Unfortunaly the same NPE occurs in all the cases.
Any assistance will be much appreciated,
Thanks !
