Title: Uniqueness In Generated XML Objects

Hi,

I'm using Castor 0.8.11 and whenever I do a SELECT query with a WHERE IN LIST clause containing negative Long values (e.g. select obj from MyObject obj where myUId in list(-10, -20)),

I get the following exception :

 

org.exolab.castor.jdo.QueryException: The LIST can only contain literals and Keywords nil and undefined.

 at org.exolab.castor.jdo.engine.OQLQueryImpl.create(OQLQueryImpl.java:535)

No such problem with positive numbers.

I know that the Castor version is very old but I can't upgrade it right now. Any idea of what causes this problem and how to fix/work around it?

 

Many thanks,

Al.
