----------------------------------------------
Summary: CdiQueryInvocationContext#isNew isn't portable across jpa
providers
Key: DELTASPIKE-948
URL: https://issues.apache.org/jira/browse/DELTASPIKE-948
Project: DeltaSpike
Issue Type: Improvement
Reporter: Daniel Cunha (soro)
Assignee: Daniel Cunha (soro)
Ww use PersisteceUnitUnitl for it, however - see the javadoc for it:
http://docs.oracle.com/javaee/6/api/javax/persistence/PersistenceUnitUtil.html#getIdentifier%28java.lang.Object%29
Solution:
I guess the only portable check is EntityManager#contains and if it returns
false a #load with the id >if< the id is available, the part with #contains
just to be faster with entities which are really loaded by the em, well -
instead of #load a count query would be better to avoid that it really loads
the entity.
