Traceback (most recent call last): File "netsvc.pyo", line 489, in dispatch File "service\web_services.pyo", line 599, in dispatch File "osv\osv.pyo", line 122, in wrapper File "osv\osv.pyo", line 176, in execute File "osv\osv.pyo", line 167, in execute_cr File "C:\Program Files\OpenERP6.0\Server\addons\syst_hr_payroll_ma\hr_payroll_ma.py", line 154, in compute_all_lines File "osv\orm.pyo", line 181, in <lambda> File "C:\Program Files\OpenERP6.0\Server\addons\syst_hr_payroll_ma\hr_payroll_ma.py", line 674, in compute_all_lines File "C:\Program Files\OpenERP6.0\Server\addons\syst_hr_payroll_ma\hr_payroll_ma.py", line 518, in get_igr TypeError: 'bool' object is unsubscriptable

And here is the line of code concern:

def get_igr(self, cr, uid, ids, montant, cotisations): #print('fonction IGR') res = {} taux=0 somme=0 salaire_net_imposable = 0 pool = pooler.get_pool(cr.dbname) id_bulletin = ids[0] bulletin = pool.get('hr.payroll_ma.bulletin').browse(cr, uid, id_bulletin) personnes = bulletin.employee_id.chargefam logement = bulletin.employee_id.logement params = self.pool.get('hr.payroll_ma.parametres') ids_params = params.search(cr, uid, []) dictionnaire = params.read(cr, uid, ids_params[0]) fraispro = montant * dictionnaire['fraispro'] / 100 if fraispro < dictionnaire['plafond']: salaire_net_imposable = montant - fraispro - cotisations - logement else : salaire_net_imposable = montant - dictionnaire['plafond'] - cotisations - logement

    objet_ir = self.pool.get('hr.payroll_ma.ir')
    id_ir = objet_ir.search(cr, uid, [])
    liste = objet_ir.read(cr, uid, id_ir, ['debuttranche', 'fintranche', 'taux', 'somme'])
    for tranche in liste:
        if(salaire_net_imposable >= tranche['debuttranche']/12) and (salaire_net_imposable < tranche['fintranche']/12):
            taux = (tranche['taux'])
            somme = (tranche['somme']/12) 

    ir_brute = (salaire_net_imposable * taux / 100) - somme
    if((ir_brute - (personnes * dictionnaire['charge'])) < 0):
        ir_net = 0
    else:
        ir_net = ir_brute - (personnes * dictionnaire['charge'])
    res = {'salaire_net_imposable':salaire_net_imposable,
         'taux':taux,
         'ir_net':ir_net,
         'credit_account_id':dictionnaire['credit_account_id'][0],
         'frais_pro' : fraispro,
         'personnes' : personnes
         }

    return res

So I apologize for the inconvenience and I hope you can help me thank you in advance
