I came up with another solution: a generic (reusable) nested_sequence
renderer.

This functions is like the standard sequence render, but instead of
using the "standard" data, it calls a nested_'data_directive_name'
method of the Page instance.

For this to work, there is the need to store the last used data
directive in the context.

II will try to write some code.
I know this is an hack, but it seems to be a reusable pattern.



P.S.
I'm looking at DataFactory and I don't understand this:
	if args:
            return callable(*args)

What's happening here?



Thanks and regards  Manlio Perillo
