Hello,

I am working with the product.product class that inherits by delegation from product.template. I want to access field uos_id from the parent class. The field is defined as fields.many2one('product.uom', 'Unit of Sale',help='Some text').

I tried to access the fields as follows:

product_obj = self.pool.get('product.product')
product = product_obj.browse(cr, uid, product_id, context=context2)
uom = product.uos_id

The code crashes some lines further because (I guess) the variable is empty. I suspect the issue is in the way I access the many2one field because when I use field uos_coeff from the parent class, it works fine (the field is defined as a fields.float('Unit of Measure -> UOS Coeff', digits_compute= dp.get_precision('Product UoS'), help='Coefficient')

Any idea of what's wrong?
