Selection field with if in Domain

[Daniela Barroso]

Hi!

I need to make a selection field that must to change the options basead in an other selection field.
I tried to do with domain and If, but the selection doesn't load the options.

doador = fields.Selection([(None, ''),
                                             ('dv', 'Vivo'),
                                             ('df', 'Falecido')], 'Doador')
tipagem_hla = fields.Selection([(None, ''),
                                                     ('idem', u'Idêntico'),
                                                     ('haplo', u'Haploidentico'),
                                                     ('dist', u'Distinto'),
                                                     ('miss', u'Missmatches')],
                                                     u'Tipagem HLA',
                                                     domain=[(
                                                                      If((Bool(Eval('doador') == 'dv')),
                                                                          ([('tipagem_hla', '=', None),
                                                                          ('tipagem_hla', '=', 'idem'),
                                                                          ('tipagem_hla', '=', 'haplo'),
                                                                          ('tipagem_hla', '=', 'dist')]),
                                                                        ([('tipagem_hla', '=', None),
                                                                           ('tipagem_hla', '=', 'idem'),
                                                                           ('tipagem_hla', '=', 'haplo'),
                                                                           ('tipagem_hla', '=', 'dist'),
                                                                           ('tipagem_hla', '=', 'miss')])))] )

Can anyone help me?

With your domains, there are no value ever possible.
The field tipagem_hla can not be None and 'idem' and 'haplo' and 'dist'
at the same time.
domain lists with no initial operator are 'AND'.
