[Alejandro Santana <alejandrosantana@xxxxxxxxx>]

Confirmed in Linux (Kubuntu 12.10 and 13.10).

Also, the proposed patch seems to solve the problem.
Should anyone do a merge proposal with such modification (I can do it myself if Fabio agrees).

  3) I'm expecting to have BoM duplicated.

  4) I'm working on Windows XP, with Google Chrome as browser.
    
  5) I'm working on openerp-7.0-20130901-231054 server version on Debian 7.0 server.
  This crash happens only on unix servers and not on windows ones.
  In my configuration I added some fields to mrp_bom :

  class plm_relation(osv.osv):
      _name = 'mrp.bom'
      _inherit = 'mrp.bom'

      _columns = {
                  'state': fields.related('product_id','state',type="char",relation="product.template",string="Status",store=False),
                  'engineering_revision': fields.related('product_id','engineering_revision',type="char",relation="product.template",string="Revision",store=False),
                  'description': fields.related('product_id','description',type="char",relation="product.template",string="Description",store=False),
                  'weight_net': fields.related('product_id','weight_net',type="float",relation="product.product",string="Weight Net",store=False),
                  'uom_id': fields.related('product_id','uom_id',type="integer",relation="product.product",string="Unit of Measure",store=False),
                  'child_complete_ids': fields.function(_child_compute, relation='mrp.bom', method=True, string="BoM Hierarchy", type='many2many'),
                 }

  plm_relation()

  And debugging server I can notice that in unix server, on
  osv/fields.py :

  
      def postprocess(self, cr, uid, obj, field, value=None, context=None):
          if context is None:
              context = {}
          result = value
          field_type = obj._columns[field]._type
          if field_type == "many2one":
              # make the result a tuple if it is not already one
              if isinstance(value, (int,long)) and hasattr(obj._columns[field], 'relation'):
                  obj_model = obj.pool.get(obj._columns[field].relation)
                  dict_names = dict(obj_model.name_get(cr, uid, [value], context))
                  result = (value, dict_names[value])

          if field_type == 'binary':
              if context.get('bin_size'):
                  # client requests only the size of binary fields
                  result = get_nice_size(value)
              elif not context.get('bin_raw'):
                  result = sanitize_binary_value(value)

          if field_type == "integer" and value > xmlrpclib.MAXINT:
              # integer/long values greater than 2^31-1 are not supported
              # in pure XMLRPC, so we have to pass them as floats :-(
              # This is not needed for stored fields and non-functional integer
              # fields, as their values are constrained by the database backend
              # to the same 32bits signed int limit.
              result = __builtin__.float(value)
          return result

  Here, the last condition (if field_type == "integer" and value > xmlrpclib.MAXINT) with uom_id field results true (and it shouldn't be, or better it should be evaluated better).
  On Windows server it results false. More precisely value > xmlrpclib.MAXINT changes its evaluation.
  When you're evaluating uom_id type is integer but value is browse_record: browse_record(product.uom, 1).

  I tried to patch it with :
               if isinstance(value, (int,long)):
                   result = __builtin__.float(value)

  instead :
              result = __builtin__.float(value)

  But, of course, is your decision on how to solve it.

  Thanks
