Hi all.

I have a problem with the display of a date value in the web client.
The date is 1899/12/30.
Imported from legacy data as datetime.date value.
So the date value is correct (no Python or ORM error).

Any workaround, how to enable the web client to display this value?

Thanks in advance

Best regards
Thomas

class Licence(models.Model):
   _name        = 'licencetool.licence'
   name         = fields.Char(string='Licence')
   ...
   validto      = fields.Date(string='Valid to')
   ...
----------------------------------------------------------
>>> lm=env['licencetool.licence']
>>> l=lm.search([('name','like','JK-Ho%')])
>>> l
licencetool.licence(275,)
>>> l.validto
'1899-12-30'
>>>

So it's correct in the database.
1899-12-30 is a correct date and is used as indicator for endless.
