How to deal with @api.depends recursion in v8?

Question

Hi.

I need to have a field A that is recomputed when a field B is changed.

But also need that field B is recomputed when field A changes.

I tried using two @api.depends methods, dealing myself to avoid actual infinite changes. But Odoo just throws a recursion error making this way impossible.

In version 6.1 and 7.0 I used some ugly hacks like onchange methods and dummy boolean fields, or trying to use the context to set a flag to cut the changes (still fighting with it). And that's what I am

Also see my question about the usage/update of context:  https://www.odoo.com/forum/help-1/question/how-to-actually-use-and-modify-context-71903 [1]

So far, in this situation (A may modify B, B may modify A):

@api.depends: impossible. Simply raises errors and Odoo server crashes.
@api.onchange + context: no way if I cannot update context.
@api.onchange + readonly boolean fields: It looks the only way, like in v6.1. But it is ugly, weird, hard to implement and completely sends to hell the promi

Yes you can use @api.depends( field A) and then define your method which compute value of field B. In @api.depends, onchange is default. That means whenever you change value of field A it will recompute value of field B. If you need more clarifications, Iet me know, I can help you.
