Many To Many Widget Question

Hi, I’m testing this widget, And I found that the list box doesn’t show all the values I spected. I have the typical many-to-many relation, from table_a, Table_b, Table_rel_ab. I’m updating or creating a record in table_a, and the list box of the relation is empty. If I add a record on table_reb_ab, I start seeing data.

Any suggest?

I created a relation in table_a model:




'Alumnos'=> array(self::MANY_MANY, 'AlumnoCuotaDefAnual', 't_alumno_cuotadefanual(fk_alumno_id, fk_cuota_def_anual_id)'),



The model 'AlumnoCuotaDefAnual? also have the relation:




return array(

			'fkAlumno' => array(self::BELONGS_TO, 'Alumno', 'fk_alumno_id'),

			'fkCuotaDefAnual' => array(self::BELONGS_TO, 'CuotaDefAnual', 'fk_cuota_def_anual_id'),

		);



Best regards
