Have you tried this(not tested)?
ingrediententry
@init {
List<int> li = new List<int>();
}
// ingredient returns an id
: q=number uid=unit iid=ingredient
(qid=ingredient_qualifier {$li.Add($qid);} )*
{…
What you might try as an alternative:
AFAIK if you write this
qid+=ingredient_qualifier*
qid will be of type List and contrain the results of the rull calls as elements.
