Subject iBatis 2.2.0 and Spring Framework 2.0 Bug
Date Fri, 08 Dec 2006 16:02:41 GMT
This happens when executing a query for list that has a subselect.  We are
using the SqlMapClientDaoSupport and setting the data source in each DAO
instead of in the SQLMapClient.  However, by setting the data source in the
the SQLMapClient, then it works fine.


We investigated but we are not sure why this happens.

Here is the stack trace:
