[eclipselink-users] eclipselink bug with weld proxy
|
Hello,
Part of an object graph I'm trying to merge is returned by a CDI
@Producer method, which gives me a proxied object.
It seems that merging this graph gives below NPE.
While debugging, I noticed I have an object A with a relation to B and B
is proxied, B.id == null but B.getId() != null. Guess that's the problem?
What can I do?
I'm using Glassfish 4.1 and EL 2.5.2.
java.lang.NullPointerException
