Problems down-casting in WHERE clause

I have a family of related types, like this: @Entity class Base { String val1; String val2; }; @Entity class Derived1 extends Base { String val3; }; @Entity class Derived2 extends Base { String val4; };  I'm trying to implement a query which will return all Base objects which have a given string within any of their String-typed fields.  The query I'm using looks somewhat like this: #1 2013-07-07 03:04 I have a family of related types, like this: @ Entity class Base { String val1 ...

PersistenceManager.getObjectsById(Collection,boolean) throwing JDOException

I have a call to getObjectsById(Collection,boolean) that is throwing a JDOException the first time I'm attempting to retrieve an object. If I try again, then the second request succeeds. Any idea why this might occur? We're using ObjectDB 2.2.4_02. The collection being passed in is a HashSet<Object> containing a single oid object (the method is written to support multiple objects, but it seems to only be failing irregularly when only a single oid is present). I'm passing false in as the verification argument.... Next build could be generated as soon as the problem is fully understood. I am not sure that ...

java.lang.NullPointerException when using ORDER BY

We are using ObjectDB 2.5.1_04. The following query causes an internal null pointer exception: SELECT r FROM RecordingMetaData AS r WHERE ((r.mapToCli != '192.168.10.200:9085' AND r.callDirection == 0)) ORDER BY r.startDateTime DESC If we remove the ORDER BY part, the query completes OK and returns the records from the DB, but obviously not in order.
