Toplink issues with Entities in the Ids

It appears that when using entities with composite IDs in association with the @Ids of an Entity, Toplink runs into many problems. Although I could (and hope to) be wrong about this, there is some evidence. The error message thrown is: Exception Description: The parameter name [itemname] in the query's selection criteria does not match any parameter name defined in the query. Where "itemname" is the referencedColumnName of a join with an Id of the target entity. This error is invoked by making use of the @OneToMany Set (which is complemented by a ManyToOne relationship in the problematic entity). Here is the full stack trace (entities.cm.ContentManagedPage_Item_Link is the problematic one with the ManyToOne. entities.cm.ContentManagedPage_Item has the field itemname and the OneToMany): Exception [TOPLINK-6094] (Oracle TopLink Essentials - 2.0 (Build b46-beta3 (05/09/2007))): oracle.toplink.essentials.exceptions.QueryException Exception Description: The parameter name [itemname] in the query's selection criteria does not match any parameter name defined in the query.

Hi Sean, I am not aware of any problems with using composite ids in TopLink Essentials. What do your mappings look like?
