Hi support,
Its me again!
My Isis version is 1.14.0, thanks for the help. Now we used DN's data
federation to managed multiple databases.
But there are some exceptions here, that's
org.datanucleus.exceptions.NucleusException: Not yet supported for queries with
unknown candidate.
Then I went to track the source code，I found the
org.apache.isis.core.runtime.system.persistence.PersistenceSession.newJdoQuery(Class<?>
cls) used org.datanucleus.api.jdo.JDOPersistenceManager.newQuery(Class cls) to
create javax.jdo.Query,
and then execute
org.datanucleus.api.jdo.JDOPersistenceManager.newQuery()，that's invoke
newQuery("javax.jdo.query.JDOQL", null).
Now,variable query is null,when invoke
org.datanucleus.store.federation.FederatedQueryManagerImpl.newQuery(String
language, ExecutionContext ec, Object query) will throw new
NucleusException("Not yet supported for queries with unknown candidate").
Is my configuration wrong?
Ekko.
