Required fields changing to red without validation

While testing review11461002:

When moving between required fields with Tab, all required fields without values are displayed at once in red color.

added tryton type::behavior + 1 deleted label

Can not reproduce.

I couldn't reproduce easily either (perhaps it was releated to review10461002), but here I found one occurence:

on tip with review11461002 applied:

- Get a database with module production installed (like scenario_production.rst).
- New production
- Select product
- On field BOM make new BOM
- On the new BOM hit New on Inputs
-> Quantity is already shown in red, others in violet.

This is not linked at to tab.
msg18068 describes just the domain inversion. I don't know if it is really an unexpected behavior.

Mark as a wish because the bahevior is the one expected by the design.

Depends on how design is defined. From the point of view of the user
- this behavior is different from previous version
- is disturbing and doesn't make sense ("Why are fields turning to red, while I am filling in values?" It feels like punishment without cause...)

I would really wish, we could have back the previous behavior for a better user experience.

Patch is welcome.

This also happens on pre_validate, see #4288 (closed) in order to get the steps to reproduce it.

For the purchase pre_validate, I think it could be solved by using a Pyson version:

[If(~Eval('field'), ('field', '!=', None), ()), …]

Because it will remove respected constraint from the domain inversion.

I can not more reproduce this on latest version.
