UnpicklingError: Global and instance pickles are not supported

[Marco Pattaro]

in object account.voucher, every time onchange_price() is called, this traceback pops up several times per call:

Traceback (most recent call last):
  File "/home/mpattaro/openerp/openerp-server-6.0.1-rev3341/bin/service/netrpc_server.py", line 69, in run
    msg = ts.myreceive()
  File "/home/mpattaro/openerp/openerp-server-6.0.1-rev3341/bin/tiny_socket.py", line 88, in myreceive
    res = unpickler.load()
UnpicklingError: Global and instance pickles are not supported.

This is not happening with GTK.
I'm using version 6.0.1

Hello ,

I have tested your scenario successfully at my end but did not face any problem.
Would you please provide more information or producible steps or Screenshots.

Thank you.

[Stephane Wirtel (OpenERP) (stephane-openerp)]

1. Could you check if there is no problem with an Exception from the server to the client (gtk or web).
2. the problem is only with the net-rpc .

Thanks.

Do you have a fix for this bug ?

Hi,

I got this error on the web client this week, for me the web client is try to pickle TinyDict class instance without converting it to standard dict. (it got this when calling an on_change on a one2many field as parameter),

Cheers,

Hi,

I have the same issue with account.voucher. Click on menu Customer Payment, click New to create. Then click on Tree View, this error will occur.

Cuong: tried reproducing this: created new database using latest 6.0 bzr (server, addons and client) went to Accounting > Customers > Customer Payment, clicked [New] (switched to form edit/create view) and back to the tree view (via the [Search View…] leftmost switcher button).

No error on either Firefox 5 or Webkit trunk, client is configured to use net-rpc on port 8070 (default).

Xavier: was your test on one of your own addons, or one available in a public repo?

Addendum: I also tried it on suppliers voucher, I get calls to onchange_price() (as hinted to by Marco Pattaro) but can not repro errors.

Got this error with a web addon I'm writting, adding more complete traceback. It seem to be triggered when trying to raise an exception

This bug is being closed as Won't Fix in the OpenERP Web Client project, as it is not going to be developed further after the 6.0 series. It will be replaced in 6.1 by a newer and better web frontend known as the OpenERP Web project[1], so further R&D efforts on the 6.0 project would be wasted.
Bugs affecting customers in production of course continue to be handled via the OpenERP Enterprise (OPW) maintenance service.
You can find more details about this in the Bug Management FAQ[2].
