Reference to outer parameter in nested repeat does not work

[tivv]

Mapper:

<update id="velocity-nested-ref" lang="velocity">
    #repeat( $_parameter.list $level1)
    #repeat( $level1 $level2)
    @{level1}
    #end
    #end
</update>

Test:

@Test
public void velocityTestNestedRef() throws SQLException, IOException {
    expect(connection.getAutoCommit()).andStubReturn(false);
    expect(connection.prepareStatement("\n" +
            "                        ?\n" +
            "                ?\n" +
            "                                ?\n" +
            "                ?\n" +
            "                    ")).andReturn(statement);

    replay();

    SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(
            Resources.getResourceAsStream("configuration.xml"));
    SqlSession sqlSession = sqlSessionFactory.openSession(ExecutorType.BATCH, connection);
    List<List<Integer>> param = Arrays.asList(Arrays.asList(10,11),Arrays.asList(20, 21));
    sqlSession.insert("velocity-nested-ref", param);
    sqlSession.flushStatements();
    sqlSession.close();

}

Hi Tivv,

I am trying to verify this issue. $level1 is a list, so what is the intended output of @{level1} in your use case?

[tivv]

Well, it's a little too much simplified. Actual usage is when level1 is a bean and we try to get it's property from a nested repeat.

[mnesarco]

Ok, I got it. It is a bit hard to fix it so fast because of the structure
of the code. I will do a major refactoring but it will take a while.
