Notes

Grouping can't be performed when the output component is of table model type because the node to output aggregation result to doesn't exist.
Mapping under the loop point of grouping can't output nodes higher than the loop point.
Grouping and subsequent mapping under the loop point of the grouping aren't executed if the second handler (key for grouping) is not specified.
