Hi. Im trying to deploy openerp in a small bussiness, almost everything was working, since i fint this problem:

I have more than 2000 products, everyone with its own barcode, the barcode is not EAN13, so im using the internal reference field to store it. I can search for the product in almost every module, using the barcode scannner that is conected to my keyboard. However when i create a sales order and try to search the product via the barcode scanner, openerp returns random products. This issue is giving a lot of problems with the sales. For reference: The first two numbers of the internal reference of the product are almost everytime the same. The barcodes i use are 13 digits long. I can read the barcodes in the POS modules with no problem, also i can type mannually the barcode in the sales order to search for the product and it appears correctly. I have checked the scanner, and it inputs the product number correctly in any other application, also i can search for the product in other modules of openerp rather than the sales module.

Is there any fix for this??
