Bei dem Versuch eine HQL-Query zu erzeugen (createQuery(String) auf einem EntityManager) wirft hibernate eine NullPointerException.
Es geht um Folgende Query:
Code:
from MyClass where otherClass.industry = :industry
and ((otherClass is null and addresses[0].country = :country) or (otherClass is not null and otherClass.addresses[0].country = :country))
Folgende zwei Queries funktionieren allerdings problemlos:
Code:
from MyClass where otherClass.industry = :industry
and (otherClass is null and addresses[0].country = :country)
from MyClass where otherClass.industry = :industry
and (otherClass is not null and otherClass.addresses[0].country = :country)
