This is my code

from openerp import models, fields, api, _, exceptions
class account_analytic_account(models.Model):

    _inherit = 'account.analytic.account'

    @api.one
    @api.multi
    @api.depends('planned_resources_ids')
    def _get_horas_planificadas(self):
        """
        Calcula horas planificadas
        """
        data = 0.0

        # Recorremos los datos obtenidos
        for plan_line in self.planned_resources_ids:
            if plan_line:
                data += plan_line.plan_coste_esf_tot

        self.planned_hours = data

    @api.multi
    def _get_lines(self):
        result = {}
        for line in self.planned_resources_ids:
            result[line.id] = True
        return result.keys()

    #Properties
    planned_resources_ids = fields.One2many('planned.resources.contract', 'contract_id', _(u'Líneas de contrato'))
    planned_hours = fields.Float(compute = "_get_horas_planificadas", string = _(u'Total horas planificadas'), digits = (12, 2), store = { 
        'account.analytic.account': (_get_lines, ['planned_resources_ids'], 10)
    })

1. This sort of questions should be asked on the Q&A of Odoo website and not here. Indeed, it is not a bug report.
2. store parameter in new api is a boolean, not a dict anymore (see https://www.odoo.com/documentation/8.0/reference/orm.html#fields)
3. api.one and api.multi are mutually exclusive: self is either a record or a recordset, not both.

@npiganeau seems to have covered all the bases, closing

@xmo-odoo you think it would be possible to add labels for closed issues like "invalid", "fixed", "duplicate"? That way we could take a look at the closed issues to see problems recently resolved without having to go through the invalid issues.
