Hi,
I have a question about the "required" keyword. The Advanced Tutorial says:
"As a complement to changeable you can use required for Attributes and
References that are to be included in the constructor, but still have a
setter method."
I find that when we set a Reference collection to required, it does not
appear in the constructor. The collection reference is like:
- List<@Foo> foos required
It turns out that the code in helper.ext specifically excludes Reference
collections (see the last line):
List[NamedElement] getConstructorParameters(DomainObject domainObject) :
domainObject.getSuperConstructorParameters().
addAll(domainObject.attributes.select(a | (!a.changeable ||
a.required))).
select(a | a != domainObject.getIdAttribute()).
addAll(domainObject.references.select(r | !r.many && (!r.changeable
|| r.required)));
But Attribute collections that are "required" are included in the
constructor. Since Reference collections are specifically being excluded,
there must be a very good reason, but I cannot figure out what that is. Or
is this a bug??
Thanks,
Polly
