Hi,

I was trying to do a new object similar to calendar.event but keeping the original. I try like this in mymodule/mymodule.py:

class radar_eventos(osv.osv):
    """ Model for Events """
    _name = 'radar.eventos'
    _description = "Events"
    _inherit = "calendar.event"
    _columns = {
        'eventotipo_ids': fields.many2many('radar.eventos.tipo', 'radar_tipo_eventos_rel',
            'evento_id','tipo_id','Tipo de Evento'),
    }  
radar_eventos()

In mymodule/mymodule_view.xml:

<menuitem id="menu_eventos" name="Eventos" parent="menu_gestao_ideias"></menuitem>

With this code I don't have erros but the view is disorganized, like if I didn't have defined a view.

But if I change the name of the model to "calendar.event" everything works fine.... I really want to keep the original and create my calendar based on the calendar of openerp, someone knows what I'm doing wrong ?

Thanks

UPDATE:

With this last code the view it's ok when I go through the menu, but when I use the field in a relation view (in a view of an object that it is related to my new object radar.eventos) the view of radar.eventos is like it doesn't have any view defined. Do I forget some action view ?

Thanks
