Hi everyone,

I'm using Odoo 10 and try to customize a view in my module.

My code:

<record id="view_calendar_event_form_popup" model="ir.ui.view">

        <field name="name">calendar.event.form</field>

        <field name="model">calendar.event</field>

        <field name="inherit_id" ref="calendar.view_calendar_event_form_popup"/>

        <field name="priority" eval="2"/>

        <field name="arch" type="xml">

            <xpath expr="//field[@name='alarm_ids']" position="after">

                <field name="delete_series" attrs="{'invisible': [('recurrency', '=', False)]}"/>

            </xpath>

        </field>

    </record>

But when opening the form, I got this error:

Uncaught Error: Unknown field recurrency in domain [["recurrency","==",false]]

And I'm sure that the field 'recurrency' is existing in the object 'calendar.event'

Did I make something wrong?

Thank you.
