Prototype inheritance on account.invoice doesn't work.

[Andrius Preimantas @ hbee]

Steps to reproduce:
1. install account module
2. install module which uses prototype inheritance on account.invoice object (I created a dummy module. You can find it in attachments)
3. Try to create an invoice and receive an error:
> Unknown Error
> Field move_id not found in browse_record(test.invoice, 3)

I used openerp 6.1 nightly built server and fresh database.

Any progress on this issue? I assume it concerns not only account.invoice object, the bug should be visible throughout the system when using prototype inheritance on any object, so it's quite important problem.

[Andrius Preimantas @ hbee (andrius-preimantas)]

Ok, so that's what I've figured out so far:

All the action takes place in BaseModel class, inside create method, on lines 4233-4240:

At the beginning of new account.invoice creation, an ID is acquired for this new object. This ID is passed to _store_get_values method (line 4234) which returns a list of tuples, which looks like this:

[(10, 'account.invoice', [52L], ['number']), (50, 'test.invoice', [52L], ['reconciled'])]

Then (line 4239) _store_set_values method is invoked on every object from the list, but IDS passed for each method invocation is one of the account.invoice object, which second invocation (test.invoice object) makes illogical (because IDS belongs to account.invoice object, not test.invoice).

Of course the problem lies somewhere deeper, but this should be good entry point for solving this issue.

Hello ,

This may be related to lp:799378.
Because if we have used different _name with _inherit then this type of
error will raised.

Thanks for reporting.

Hello Ajay,

I don't think it's a real duplicate of lp:996816, as the exception is different and probably the bug as well. lp:799378, lp:996816 and this one all three are related to each other but we can not consider all as a duplicate because If we missed the one part of them then may be all things will not fixed. So I am going to remove the duplicate.

Hope you can understand!

Thank you!

Hello all,

seems similar problem persists on OpenERP v7, I'm trying to inherit sale.order by prototyping and when trying to create default object sales order I'm getting an error linked to my new object, as I understand my inheritance should have no affect to original object. The error I get:
