Daniel Keir Haywood resolved CAUSEWAY-3507.
-------------------------------------------
Resolution: Fixed
> RepositoryService#allMatches should support JDOQL that has a 'result'
> ---------------------------------------------------------------------
>
> Key: CAUSEWAY-3507
> URL: https://issues.apache.org/jira/browse/CAUSEWAY-3507
> Project: Causeway
> Issue Type: Improvement
> Components: Persistence JDO
> Affects Versions: 2.0.0-RC1
> Reporter: Daniel Keir Haywood
> Assignee: Daniel Keir Haywood
> Priority: Major
> Fix For: 2.0.0-RC2
>
>
> given this JDOQL:
> SELECT DISTINCT this.paymentMethod FROM IncomingInvoice
> it is not possible to submit using RepositoryService#allMatches(...)
>
> compared to v1, the reason seems to be that we used to use
> JDOQuery#executeWithMap(), whereas now we use JDOQuery#executeList, and the
> latter has a check for whether there is a return phrase (ie "DISTINCT
> this.paymentMethod").
> The fix, I think, is to call either JDOQuery#executeResultList rather than
> JDOQuery#executeList if there is a result phrase.
