I have tried to activate the lazy loading in iBatis. From working perfectly
without lazy loading I turn into lot's of exceptions like this one:
org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation;
uncategorized SQLException for SQL []; SQL state [null]; error code [0];
--- The error occurred in sqlMap.xml.
--- The error occurred while applying a result map.
--- Check the Library.
--- The error happened while setting a property on the result object.
--- Cause: java.lang.RuntimeException: Error setting property
'setStructures' of '[EMAIL PROTECTED]'.
Cause: java.lang.IllegalArgumentException: argument type mismatch; nested
exception is com.ibatis.common.jdbc.exception.NestedSQLException:
--- The error occurred in sqlMap.xml.
--- The error occurred while applying a result map.
--- Check the Library.
--- The error happened while setting a property on the result object.
--- Cause: java.lang.RuntimeException: Error setting property
'setStructures' of '[EMAIL PROTECTED]'.
Cause: java.lang.IllegalArgumentException: argument type mismatch

What am I doing wrong? Do I need interfaces for my domain objects? I didn't
need it when using Hibernate so I thought that maybe... Or what?
