First test works good for me. I will test it now for longer.

A question to Patch Set 4 : Allow to use switch widget between o2m and m2m

What is switch widget?

It is for https://bugs.tryton.org/roundup/issue1103
So it will allow to use the widget m2m for a o2m field and the widget o2m for a
m2m field.
