Resolution: Fixed
Assign To: Clinton Begin
Fixed as described
> Can't store a List in a Map
> ---------------------------
>
> Key: IBATIS-221
> URL: http://issues.apache.org/jira/browse/IBATIS-221
> Project: iBatis for Java
> Type: Bug
> Components: SQL Maps
> Versions: 2.1.5
> Environment: Windows XP, j2sdk1.4.2_08
> Reporter: Gary Bradshaw
> Assignee: Clinton Begin
> Priority: Minor
> Fix For: 2.2.0
> Attachments: BasicResultMap.java
>
> Nested selects (N+1 selects) with a 1:N relation work fine as long as the
> primary result set is mapped to a JavaBean, but when the primary result set
> is mapped to a Map, iBATIS ignores the javaType of the column with the select
> attribute and treats it as a simple Object. This is a problem for 1:N cases
> since it needs to treat the column as a List and use queryForList() instead
> of queryForObject() to load it.
> A small change to com.ibatis.sqlmap.engine.mapping.result.BasicResultMap.java
> seems to take care of the problem in my case, but there may be a
> corresponging change required for LazyLoading that I haven't looked into.
