inheriting class from osv.fields.one2many

I've tried without any success to inherit from one2many field. I wanted to override some methods in the new class but when openerp tries to load the module it shows a CRITICAL error in the log (no special message to understand what is the problem)

What I intended to do in my python source file is something like this:

Code:

from osv import fields

#class inherited from fields.one2many
class x_one2many(fields.one2many):

    _inout = None

    def __init__(self, obj, fields_id, string='unknown', limit=None, inout, **args):
        fields.one2many.__init__(self, obj, fields_id, string, limit, args)
        self._domain = [('type', '=', inout)]
        self._inout = inout
        

    def get(....)
        new get() code here 

...
class X(osv.osv):
...
    _columns = {
        col1= fields. ...,
... 
        coln= fields. ...,
        'coly': x_one2many('y', x_id', 'name', readonly=True, inout='in'),
    }

X()
...
class Y(osv.osv):
...

Y()

[/code]

even if I don't use x_one2many class in the code, the module doesn't load. What could be the problem?

the problem was the order of the required parameters of the constructor

inout parameter must be placed must be placed before the string, first parameter with default value
