[ceylon-dev] Java persistence interop getSingleResult()

[Travis Brown]

I'm experimenting with the Ceylon + Wildfly (JaxRS and JPA) and have a
minor API change suggestion for ceylon.interop.java.Query.

TypedQuery has this signature signature but throws NoResultException if the
entity is not found:
shared Result? getSingleResult()

I would expect this to either not return null or to allow null to mean
"entity not found".


Below in the same file, QueryResults has this signature:
shared Anything getSingleResult()

This similar method (but pertaining to a stored proc query) catches
NoResultException and returns null.


Regards, Travis

Sure, I agree, would you do me a favor and open an issue against
ceylon-sdk, please?

TIA
