FLATTEN custom bags

[Aniket Mokashi]

Hi,

I have a custom loader that creates and returns a tuple of id, bags. I
want to open these bags and get their contents.
For example-
data = load 'loc' using myLoader() as (id, bag1, bag2);
bag1Content = foreach data generate FLATTEN(bag1);
This works.

But when I do bag1Content = foreach data generate id, FLATTEN(bag1) --it
fails.
How should I fix it?

Thanks,
Aniket
