Oracle refcursor in output variable: nested mapper not recognized as being nested about mybatis HOT 3 CLOSED

There is a workaround for this problem: set the resultMap at the top-level 
select in addition to setting it at the parameter level.  For example:

    <select statementType="CALLABLE" id="getUserByLdapAlias"
        resultMap="DetailedObjUserVo"
        parameterType="MyBatisBean" resultType="object">
        call PKG_USER_DATA_SERVICE_MYBATIS.get_user_by_ldap_alias (
        #{ldapAlias}
        ,#{retvalUsers,mode=OUT,jdbcType=CURSOR,javaType=java.sql.ResultSet,resultMap=DetailedObjUserVo}
        )
    </select>

I don't know if this is the way it should work -- the resultMap of the output 
parameter being identified as nested based on whether the resultMap at the top 
level select is nested -- but it seems to be the way it works as of v3.0.1.  
This might become a problem if there are multiple output parameters and not all 
of them are nested -- not sure.

The reason that it is failing is that MappedStatement.Builder sets the 
hasNestedResultMaps value for a statement by iterating over its result maps 
like this:

    for (ResultMap resultMap : resultMaps) {
        mappedStatement.hasNestedResultMaps = mappedStatement.hasNestedResultMaps || resultMap.hasNestedResultMaps();
    }

But for these statements resultMaps is an empty collection, as it is the output 
parameter that has a resultmap, not the statement.

Fixed in SVN
