Hello,

I need to change the value of attribute "use_contacts" in calendar.event model through "xml_id" of user group:

The new code inherit from calendar.view_calendar_event_calendar, the code is:

<?xml version="1.0"?>
<openerp>
    <data>
    <!-- CRM Meeting Calendar -->
    <record model="ir.ui.view" id="crm_view_calendar_event_calendar">
        <field name="name">Meetings Calendar</field>
        <field name="model">calendar.event</field>
        <field name="inherit_id" ref="calendar.view_calendar_event_calendar"/>
        <field name="priority" eval="2"/>
        <field name="use_contacts" eval="?????"/>
        <field name="arch" type="xml">
            <xpath expr="//calendar" position="replace">
                <calendar string="Meetings" date_start="start" date_stop="stop" date_delay="duration" all_day="allday" 
                             display="[name]" color="color_partner_id" attendee="partner_ids" avatar_model="res.partner"
                             use_contacts="[use_contacts]"
                             event_open_popup="%(calendar.view_calendar_event_form_popup)s">
                    <field name="name"/>
                    <field name="user_id"/>
                    <field name="color_partner_id"/>
                    <field name="partner_ids"/>
                </calendar>
            </xpath>
        </field>
    </record>
    </data>
</openerp>

I need to find another solution or alternative.

Thank you!
