[17.0] account: debit, credit can be modified even if is posted (Big, Big Issue)

[Florent de Labarre]

Impacted versions: 17.0, 16.0 and maybe other

Steps to reproduce:
Create an account.move with line and balance !=0.
Post entry
Execute record.line_ids.write({'balance':0})
--> Issue debit credit is now zero, WTF !!!!!!

Note: after a migration V8 to V17, if you open (in V17) an posted invoice with an attachment, register_main_attachment is triggered, then a write appear, and sync_line is recomputed (it is useless because the invoice is posted). During the recomputing if there are some mitshmatch data, Odoo update the account.move.line. (same case if you reconcile)

Did you post the entry? maybe the expected behavior is that it can be modified if not posted yet.

[Florent de Labarre]

Yes on posted entry (see video)
