Hi everyone

I created a new model based on res.partner with delegation (_inherits).

I'm trying to inherit 'base.view_partner_form' to avoid copy/past most of the code and simply add/delete what a need. I think that it should works but I getting a very small javascript error message that I simply can't understand.

Model:

class MyModuleHospital(models.Model):
    _name = "mymodule.hospital"
    _inherits = {'res.partner': 'partner_id'}
    _description = 'Hospital'
 
    partner_id = fields.Many2one('res.partner', 'Related Partner',
                                 required=True, ondelete="cascade", index=True, auto_join=True)

View:

<record id="view_hospital_form" model="ir.ui.view">
        <field name="name">mymodule.hospital.form</field>
        <field name="model">mymodule.hospital</field>
        <field name="inherit_id" ref="base.view_partner_form"/>
        <field name="arch" type="xml">
           <xpath expr="//form" position="attributes">
                <attribute name="string">Hospital</attribute>
            </xpath>
        </field>
 </record>

Error:
