i tried the IN clause it get the same error.
@Basic
@Extension(vendorName="datanucleus", key="gae.parent-pk", value =
"true")
private Key parentKey;
Query chatUserQuery = em.createQuery("Select c from ChatUser c where
c.parentKey IN (:parentKeyList)");
produces error
java.lang.ClassCastException: java.util.ArrayList cannot be cast to
com.google.appengine.api.datastore.Key
at
org.datanucleus.store.appengine.query.DatastoreQuery.internalPkToKey(DatastoreQuery.java:
1484)
But when i use a normal key field everything works.
@Basic
private Key parentKey2;
Query chatUserQuery = em.createQuery("Select c from ChatUser c where
c.parentKey2 IN (:parentKeyList)");
the issue seems to be with the "gae.parent-pk" not the query.
