crm_claim categ_id domain is not working

hello,

In the module crm_claim, the field categ_id has a domain :

        'categ_id': fields.many2one('crm.case.categ', 'Category', \
                            domain="[('section_id','=',section_id),\
                            ('object_id.model', '=', 'crm.claim')]"),

However, in the view crm_case_claims_form_view, the field has the attribute widget="selection" :

                                    <field name="categ_id" widget="selection"
                                        domain="[('object_id.model', '=', 'crm.claim')]" />

So two problems appears here.
First the domain does not consider the section_id anymore.

Second, when the field is a selection, dynamical domains are not allowed anymore.

The result is that the categories showed in the selection are not depending on the section_id chosen.

Best regards,

Benoît
