Subject Re: Error when executing EJBQL generated from an expression containing outer joins
Date Mon, 07 Sep 2015 06:19:14 GMT
Likely a limitation in EJBQL. Originally we tried to stick with JPA spec for EJBQL syntax,
and that does not support + notation for outer joins. Instead it has a separate join clause.
Now we are no longer bound with JPA compatibility and can actually accept paths with outer
joins. But I guess it has never been implemented in EJBQL parser.

everything works fine.
