I think you can also say min_length=1 ... but the error message in case
the list is too short might be cryptic, IIRC.

OK figured out a workaround:
def isnotempty(value):
return bool(value)
layers = schema.List(
title=_(u"Layers"),
description=_(u"WMS Layers"),
required=True,
constraint=isnotempty,
value_type=schema.Choice(
source=layers_vocab,
required=True,
),
)

I try to make a list filed required for a dexterity type:
layers = schema.List(
title=_(u"Layers"),
description=_(u"WMS Layers"),
required=True,
value_type=schema.Choice(
source=layers_vocab,
required=True,
),
but when I save the edit form it does not complain wether
the list field is filled or not

If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.
1) Don’t drive species to extinction
2) Don’t destroy a habitat that species rely on.
3) Don’t change the climate in ways that will result in the above.
