I tried it:
List<DBObjectAccess>accessList = (List<DBObjectAccess>)
query.execute(user.getKey());
ArrayList<Key> ids = new ArrayList<Key>();
...
query = pm.newQuery(DBPurchaseItem.class,
":idCollection.contains(id)");
List<DBPurchase> dPurchases = (List<DBPurchase>)query.execute(ids);
and catch Exception:
org.datanucleus.store.appengine.query.DatastoreQuery
$UnsupportedDatastoreFeatureException
Problem with query <SELECT FROM
ru.abc_software.shoplist.server.data.DBPurchaseItem
WHERE :idCollection.contains(id)>: Unsupported method <contains> while
parsing expression:
InvokeExpression{[ParameterExpression{idCollection}].contains(VariableExpression{id})}
