Hello Niels,
I'v found another solution for my problem. In the Class SelectionListQuestion
which extends the Question Class described in my first mail, I had to implement
two "proxy methods" that take as parameter Collection Objects:
public Collection getCollection() {
if (this.getResponse instanceof Collection) {
return (Collection)this.getResponse();
}
return new ArrayList();
}
public void setCollection(Collection col) {
this.setResponse(col);
}
In the Binding I have to point to this methods for multivalue fields and it
works. I don't no why, but it works.
Thanks,
Mike
