Folks, z3c.form.converter.FloatDataConverter does not tolerate more than 3 digits after the decimal point, ever. That's UX fail for Dexterity types, and pretty much any z3c.form using stock converter, which is every form with a zope.schema.Float field AFAICT. This is due to regex validation in formatter from zope.i18n, can we fix this?
For now, I'm writing a converter override in my add-on, but this seems a curious problem. Can we fix this in plone.zpp.z3cform, perhaps? I'm happy to contribute that and docs if there isn't some other solution I am unaware of.
