    public Perfiles buscarPerfil(ObjectId id)
            {
                    ObjectIdQuery query = new ObjectIdQuery(id);
                    this.p = (Perfiles) DataObjectUtils.objectForQuery(this.dc, query);
    // this.perfiles.add(this.p);
    // return this.perfiles;
                    return this.p;
            }

    this is my buscarPerfiles method... its return a global uninitialized var.

    and btw this is my delete perfil methos...
    public void borrarPerfil(ObjectId id)
            {
                    this.p = this.buscarPerfil(id);
                    this.dc.deleteObject(this.p);
                    this.dc.commitChanges();
            }
     and it works... I'll try to be sure that I am creating the object
    into the datacontext.

    thanks for the replies btw
