In _require_element right after populate()

For the first time for every element in the form (via ObjectUtil, see above)
and then a second time if an element is contained within a block element
because block.pm overrides setup() to call setup() on every sub element
of itself. So setup() is called twice for elements which are contained in a
block element.

It subclasses multi to build up a three-select-field date element. See the
other mail I just fired off to the list.

Nope, it's not :)

Thanks!
