Hi Anthony!
You have written:
Not sure what you mean. When I try it, I get the expected list of record
IDs in request.vars.records as well as the value of "f" in request.vars.f.
The list in *request.vars.records* is ultimately passed to the "selectable"
function, after which, the redirect happens. Can you explain exactly what
you are doing, what you expect, and what you see instead?
The important part is "*in request.vars.records*". Yes - there are the
expected values. Maybe this information ("vars.records") in somewhere in
the book or in the source text - but I did not find it. Again:
request.vars.records solves the problem - I think, this information is
worth to be mentioned in the book!
Thank you both for helping!
