[[ repeatIn(objects,'l') ]]

[[ l.date_contrat ]]

[[ repeatIn(l.lst_termes,'lst_termes') ]]

[[ lst_termes.descriptionterme ]]

i dont know why the origin of the error : object l is not defined. please someone help me. i want to say tha this is the relation between contrat and terme

class contratcommercial(osv.osv):
    _name='contratcommercial'
    _inherit='contrat'
    _rec_name = 'titreContrat'
    _columns = {
        'id_partenaire_commercial':fields.many2one('commercial','Commercial'),
        'lst_termes':fields.one2many('terme','id_contrat_comm','Liste des termes'),
