[html-formfu] Constraint "Required" with condition "when" doesn't work in apache-style config

[Christoph Metz]

using an Require constraint whith the "when" condition doesn't work fine =

for me :/

<element>
            type Select
              name kompetenzfeld_id
              <constraint>
                type Required
                <when>
                    field extern
                    values 0
                  </when>
            </constraint>
</element>


without the "<when>" part the Required constrain works correctly, maybe =

the syntax of my conf isn't correct, but this was the only variant, =

(config-loader) formfu accepted so far...

by the way, thanks to Carl for his answer, get_all_element() works =

perfectly! :)
