[8.0] functions fields in tests are not computed with new api

[JulioSerna]

After this commit some of our tests that are validating the distinct values of the functions fields into process are failing

Impacted versions:

• 8.0

Steps to reproduce:

• Create functions field with new api like this invioced2
• Create tests to validate value for this field before and after the pay invoice

Current behavior:

• The function fields only is calculated the first time, the second time is not calculated

Expected behavior:

• The field function must be calculated in all test

@rco-odoo Can you have a look at this issue?

Hello,

Your field is not correctly defined. For a computed field, you should define the dependencies thanks to @api.depends. In your case, this should probably be the solution:

@api.depends('state', 'invoice_ids')
def _invoiced2(self):
....

Please read https://www.odoo.com/documentation/9.0/reference/orm.html#computed-fields
