symfony - Duplicate control using ShtumiUsefulBundle Symfony2 -

i'm using shtumiusefulbundle. config section in application:

shtumi_useful : dependent_filtered_entities:     ciudad_by_dpto:         class: gestionbundle:ciudad         parent_property: dpto         property: nombreciud         role: is_authenticated_anonymously         no_result_msg: 'no hay regiones encontradas'         order_property: nombreciud         order_direction: asc 

this configureformfields

$formmapper         ->add('nombre')         ->add('email')         ->add('urlcurriculum')         ->add('cargo')         ->add('departamento')          ->add('ciudad', 'shtumi_dependent_filtered_entity', array(             'entity_alias' => 'ciudad_by_dpto',             'empty_value' => 'select',             'parent_field' => 'departamento',             'required' => true,          ))     ;
