I need it here: _columns = { 'stock_real': fields.function(nfx_product_value, type='float', string='Real Stock', multi="product"), }

def nfx_product_value(self, cr, uid, ids, field_names, arg, context=None): need id of product here... (ids has stock_location_ids only...)

def nfx_product_value(self, cr, uid, ids <--- this is a list with all the id..if there is only 1 id, you can take it with ids[0]

no, ids is a list with stock_location ids. I need the product id in this function and the location ids...

What file and what line have you this code? So I can read it, too..

self made module. you can see part of it here: http://help.openerp.com/question/8598/how-can-i-pass-context-to-a-one2many-field/

function test is called and returns location ids. this location ids are passed to the fields complete_name, stock_real and stock_virtual

If I don't know all the code and the context when is it inserted I can't help you...I'm sorry

to calculate the real_stock of the product, I need the id of the location and the product too...

ok, thank you. that's why I want the id from the url... :-(

If you print the context, can you see the product_id?

no, the product_id is not in the context. I tried add it manually with <field name="stock_real" context="{'product_id': 49}"/> but it don't works.
