Strange - params.nil? true in controller

Hi All
I am trying to implement a functionality where a user clicks on “Back to
Search Results” link he is taken to the search result screen. For this I
am
storing his search criteria (params object) in session. Here is my code


def search

logger.debug(“params.nil?=#{params.nil?}”) # this prints
'params.nil?=false’
<=== params is NOT nil at this point

if session[:incidentSearch].nil? or
session[:incidentSearch].empty?

params.each{|k,v| logger.debug(“key: #{k}, value: #{v}”)} #this
prints
the key value pairs perfectly

logger.debug(“params=#{params.to_s}”) # this prints
‘params.nil?=false’ <===
params is NOT nil at this point

s=params.dup

params=s

logger.debug(“params=#{s.to_s}”)

if params[:routeNum].nil? or params[:routeNum].empty? <===
params
is NOT nil at this point

flash[:warning] = “Don’t try stupid things…Enter some search
criteria.”

redirect_to :back and return

elsif !params[:routeNum].empty? and one more condition

flash[:warning] = “Specify only one search criteria Reference# or
Route or
Date (Start and End both)”

redirect_to :back and *return

*end
*

params.each{|k,v| logger.debug(“key: #{k}, value: #{v}”)}

elsif !session[:incidentSearch].nil? and
!session[:incidentSearch].empty?

control never reaches here for the first time the search is done

logger.debug("======> Somebody was here…") # <== control never
reaches here for the first time the search is done

params = session[:incidentSearch] # *<== *control never reaches
here,
if
I comment it every thing works fine i.e. params is never nil

puts “*^&^&^(^%%^%&^$%$%$&%$&$&^$&^ Somebody was here…” #
<== control
never reaches here and nothing is printed

*end

  • logger.debug(“params.nil?=#{params.nil?}”) # this prints
    ‘params.nil?=*
    true*’ <=== params is NIL at this point.

#proceed with search…


This is a single user development environment. So only one request comes
in
for a search… and the params is nil before I can even proceed with
search.

Can somebody please help me understand where and why is params being set
to
nil???

Oh and if I do the following in my first if

s=params.dup
params=s

everything works fine

This is completely wierd since the elsif
!session[:incidentSearch].nil?
and !session[:incidentSearch].empty? is never executed.
Anybody has any ideas.???
