> I was one of the user who use Hibernate in a legacy database schema, and always had a issue on using composite-key (and formula) inside collection. I was able to modify the hibernate source (from 3.3.2) to overcome such issue. I am hoping the new version 3.5.0 would even fix this problem. Anyway, I just leave the fix information here, hope it would help.
> In /org/hibernate/loader/JoinWalker.java
> Line 641: String[] aliasedLhsColumns = StringHelper.qualify(alias, lhsColumns); 
> Modify with these:
>   String[] fullAliasedLhsColumns = persister.getElementColumnNames(alias);
>   String[] aliasedLhsColumns = ArrayHelper.slice(fullAliasedLhsColumns, begin, length); 
> Without above change I would get NullPointerException on a mapping as
