MiniLang's first-from-list behaviour

[Scott Gray]

Hi All,

I noticed the <first-from-list> element does nothing if the list is
either null or empty (i.e. the field retains it's current value), I
was expecting that it would set the field to null.  I would like to do
one of two things, either change the behaviour of the element or
document the element so that people are aware of its current
behaviour.

Any opinions on which?

Thanks
Scott

It seems to me it should return an empty field.

Well, when you put it that way...

Yes I think we should change the behavior and have it set the value to null if the list is null or empty. That seems totally reasonable.
