Ini related kalo equals dan hashcode nggak di implement properly.
Coba add ini method di User object.
<code>
public boolean equals(Object object)
{
if (this == object)
{
return true;
}
if (!(object instanceof User))
{
return false;
}
final User that = (User)object;
if (this.id == null || that.getId() == null || !this.id.equals(getId()))
{
return false;
}
return true;
}
public int hashCode()
{
int hashCode = 0;
hashCode = 29 * hashCode + (id == null ? 0 : id.hashCode());
return hashCode;
}
</code>
