I swear I had this working before, but now its not. I have a simple HQL of:
Code:
SELECT DISTINCT tbl FROM AccountFee tbl WHERE tbl.account IN (:account)
I set the :account = an array of account objects. AccountFee.account is an Account object with an Account having many fees.
I get the following stack trace when I try to execute this:
Code:

Caused by: java.lang.IllegalArgumentException: Can not set long field Base.id to java.util.ArrayList
at java.lang.reflect.Field.get(Field.java:358)
at org.hibernate.property.DirectPropertyAccessor$DirectGetter.get(DirectPropertyAccessor.java:32)
Base is the Parent type of Account, id does have getters/setters, I can do FROM AccountFee where account.id = 4
The sql looks fine, the import bit being:
Code:
... from AccountFee accountfee0_ where accountfee0_.account_id in (?)
Any ideas on what I'm doing wrong or if this just isn't possible? I'm using hibernate 3.2.5ga
Thanks for the help!
