> The POCasts resulting from the following scripts have a null load Function
> reference which leads to run time null pointer exceptions:
> Script 1:
> {code}
> a = load 'a' as (s);
> b = foreach a generate s#'a' as x;
> c = foreach b generate (int) x#'a' as intx;
> {code}
> Script 2:
> {code}
> a = load 'bla' as (s, m, l);
> b = foreach a generate s#'x' as f1, s#'y' as f2, s#'z' as f3;
> c = group b by f1;
> d = foreach c {
> fil = filter b by f2 == 1;
> generate flatten(group), SUM(fil.f3);
> }
> {code}
