Hi Ive got a subclass, and I use this subclass on a bag, however I want to use the order by from the base class.
<bag name="operates" table="SYS_Project_Operate" inverse="true" lazy="false" cascade="delete" order-by="addDate">
...
<class name="Operate" table="SYS_Operate">
<property name="addDate" column="addDate" type="string" length="19" />
<joined-subclass name="Project_Operate" table="SYS_Project_Operate">
...</joined-subclass>

it throw a exception,nested exception is:
Unknown column 'operates0_.addDate' in 'order clause'

thanks in advance
