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
Priority: Minor
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.
