Subject: [PATCH] [FIX] web: FieldX2Many must use AbstractManyField is_false
 method

If the method return false, when a user write require="1" on a x2many field, the content is valid that there have none or a value.

The method was overwrited for a visual change (display the field x2m in readonly mode when they are not value) but is_false is priority use to ensure datas.
