>                 Key: IBATIS-427
>                 URL: https://issues.apache.org/jira/browse/IBATIS-427
>             Project: iBatis for Java
>          Issue Type: New Feature
>          Components: SQL Maps
>    Affects Versions: 2.3.0
>            Reporter: Andrew Bethell
>
> (Added this issue as a new feature, as I cannot find any documentation or instructions on how to implement this with iBATIS.)
> I have the same requirements described here : http://www.mail-archive.com/user-java@ibatis.apache.org/msg00962.html - in a nutshell I have an 'Order' object which contains a List of 'OrderItem' objects (lazy loaded), but I want the OrderItems to contain references back to the parent 'Order' object (also using a lazy-load property).  
> At the moment iBATIS runs into an infinite loop when I try this (StackOverflowError), and from reading the email thread I mentioned above - it seems like this functionality is not implemented.  However, this discussion thread here - http://www.theserverside.com/news/thread.tss?thread_id=34028#171643 - has a comment from one of the iBATIS developers claiming that circular references are supported - 
> "Resolves circular references - iBATIS solves circular references the same way O/R broker does...with a cache. But yes, you do have to configure the cache in iBATIS for this to work."
> I had a quick go at configuring caching with ibatis, but it didnt seem to change anything.  Can anyone shed any light on this issue? 
> Thanks.
