Hi Raoua,
Replied you on the JIRA issue, for visibility also sharing it here. The
AbstractJPATypedQueryVisitor was designed to be extendable, I believe it
would make sense to open up (== protected) doBuildXxx methods so the
predicate construction could be customized. Thank you.
Best Regards,
Andriy Redko
