Silly me. Requesting the wrong (ant threrefor not-existing) property, will result in
an empty string. I even managed to create such new variables with set or ask:
<j:set var="all.${var}" value="${defaultval}"/>
<i:ask question="${prompt}" answer="all.${var}" default="${defaultval}"/>
Works great. I did not expect this, since the var and answer attributes are documented
as plain String values.
Thanks dion!
