* named "field_changed:<field_name>" with <field_name> replaced by the name of the field.
* This event is not related to the on_change mechanism of OpenERP and is always called

* value of the field is syntactically valid, but it can be triggered when the value
* is sematically invalid (ie, when a required field is false). It is possible that an event
* about a precise field is never triggered even if that field exists in the view, in that
* case the value of the field is assumed to be false.
