Mapping solution for an innerloop/outerloop scenario.

In the mapping tab, the left schema has an unbounded item record (the outerloop). The looping functoid handles that data fine. Within each item record, there is an unbounded comment record (the innerloop).

The two configurations used generate either the only first comment for each item (incomplete) or repeats all the comments for each item (completely wrong).

How do you arrange the functoids to process innerloop/outerloop data?
