Re: a word of caution about base action rules / Automated Actions

- the initial problem description about undesired side effects,
- a interim relief by maintaining workflows at least until v10
- the call for improvement of the existing workflow engine
- the hint to tryton's solution

as for design a combination of tryton's solution with the well known @depends() decorator could be worth a line of thought. The "why" is based on the following assumptions.

Asumption 1: depends() does not expose the undesired external effects which come with obscure writes in dirty fields, which are not handeled correctly by automated actions (yet). (Alexandre's Case Description)
Assumption 2: declare the transition field as a class attribute is indeed mimicking the current aproach of the magic 'state' field, but joining a dictionary of allowed transitions would bring back some of the desired control flow.
Assumption 3: The @workflow() decorator could hook a custom method into a better implementation of some/all of the mentioned improvements about ACL for example, once those are gathered and duely explained in a comprehensive document.

Please make sure you put some effort
on understanding this approach, as only refutating the core weeknesses of this approach (as in Grahan's Pyramid of refutation) are most useful, for what it's worth promoting towards solution. ;-)

Best, David

Thanks for the clarification Fabien, but this is besides the point I was
making before this thread was hijacked...
