An action handler (select_person_by_name) in my controller class assigns
into session, and then does a redirect_to. I get the error "TypeError
(singleton can't be dumped):" followed by a stack trace that doesn't
cross my code.
Google tells me this is ordinarily caused by assigning a singleton
instance into session, but what I'm assigning is an ordinary String.
This is verified by logging the value and its class.
Further, the log shows a "Redirected to" line to the URL I expect from
by redirect_to. The TypeError is reported from a SECOND attempt to
process the select_person_by_name handler.
The parameters for both invocations of select_person_by_name are as I
expect from what I did in the view.
select_person_by_name appears in my source twice: Once to def it, and
once as the :action in the form that invokes it.
Could someone please give me a further lead?

Here is the code, boiled down. Values, classes, etc., are verified by
logger calls (omitted):
===
class AdminController < ApplicationController
def select_person_by_name
# Here @people is set to be an Array with one element
case @people.size
# Other branches omitted
when 1
person = @people[0]
session[:focused_cnetid] = person.principal.cnetid
# person.principal.cnetid is as expected, it's a String,
# and it's generated from external data. ("fritza", nothing
special)
redirect_to :controller => :people, :action => :show, :id =>
person
# person.id is as expected.
end #case
end # select_person_by_name
end # class
