[8.0] Old/New API compatibility Error Into Test

[JonathanNEMRY]

Old/New API compatibility Error

Impacted versions:

• 8.0

Steps to reproduce:

1. Add a button into a form view of a model (no matter which). This button is type of object and the related method is "@api.multi" decorated
2. Into this method call the method onchange_product_id from purchase.order.line into new API
3. Click on this button: it will work and you'll receive as well the result.
4. Create a test for this method and call it into api.v8 form the test. (self.env.button_method())

Current behavior:

• the onchange_product_id crash during the call with a bad number of arguments (6 given/waiting 9)

Expected behavior:

• calling this method should run with wrapper but it seems that it is not called

Note:
@api.cr_uid_ids_context on onchange_product_id seems to fix the problem
