--------------------------------
Assignee: Andi Huber
> If return a google guava collection from an autoComplete or choices, then
> throws exception due to unsupported classes.

>
> Key: ISIS-1331
> URL: https://issues.apache.org/jira/browse/ISIS-1331
> Project: Isis
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.11.1
> Reporter: Dan Haywood
> Assignee: Andi Huber
> Priority: Minor
> Fix For: 2.0.0-M1
>
>
> For example, this seemingly innocuous code:
> {code}
> public List<SimpleObject> autoComplete(@MinLength(2) String search) {
> return
> FluentIterable.from(listAll())
> .filter(new Predicate<SimpleObject>() {
> @Override public boolean apply(@Nullable final
> SimpleObject object) {
> return object.getName().contains(search);
> }
> })
> .toList();
> }
> {code}
> will fail. to make it work, the developer needs to copy to an ArrayList, eg:
> {code}
> public List<SimpleObject> autoComplete(@MinLength(2) String search) {
> return
> Lists.newArrayList(
> FluentIterable.from(listAll())
> .filter(new Predicate<SimpleObject>() {
> @Override public boolean apply(@Nullable final
> SimpleObject object) {
> return object.getName().contains(search);
> }
> })
> .toList()
> );
> }
> {code}
> One possible solution is for the framework to do this automatically, for
> List, Set, Collection.
