First step is to fix framework to allow resetting reference values by writing
False (bool, not str!) in the field.
We need to fix orm._check_selection_field_value() and probably use a _symbol_f
= lambda x: x or None in fields.reference class.
Then we can change clients to write False when a reference fields is
emptied.

Title:
[6.0] impossible to reset reference fields
Status in OpenERP GTK Client:
Confirmed
Bug description:
Selection fields that are not mandatory can be empty. However, once you
select an entry, you cannot reset value to unselected.
There should be an empty line with no value like in the search view or like
with the widget selection on a many2one.
Another side effect is with reference fields that are composed of a
selection field as first widget. When you select an object, you are
forced to define the reference (even if optional) as you cannot
unselect any object of the drop down in order to remove the value of
the reference field.
There must be a way to reset the value of a reference field that is
not mandatory.
