I have just made an addon that adds a field to the stock.picking.out form.

Here is my code :

from osv import fields,osv
class stock_picking_out2(osv.osv):
    _name = "stock.picking.out"
    _inherit = "stock.picking.out"

    _columns = {
        'statut_id2': fields.many2one('sale.statut', 'Statut', required=True),
    }   
stock_picking_out2()


<record id="view_livraison_move_picking2_form" model="ir.ui.view">
   <field name="name">stock.picking.out.form.inherit</field>
   <field name="model">stock.picking.out</field>
   <field eval="1" name="priority"/>
   <field name="inherit_id" ref="stock.view_picking_out_form" />
   <field name="arch" type="xml">                
       <field name="stock_journal_id" position="replace" >
          <field name="statut_id2"/>
       </field>
   </field>
</record>

Everything works perfectly on my local server, but when I install the addon on a remote server I have different errors :

• I can't edit the field with the form : when I edit, the changes are not saved.

• I got this error when I try to edit a field in another form like "SALE ORDER" form :

(The error occurs for any types of fields, I tried to replace by Integer, char, etc... So I don't think that I comes from the relational field !)

I have also tried to change stock.picking.out by stock.picking in the inheritance and it worked, but I can't modify the field I want in the XML code...

The module is very simple but I can't see where my error come from... Do you have any idea to solve it?
