Hi Colin,
I don't think it is, in fact I know it isn't empty because the logic is
inside a test for the return size of 0.
if @my_names.size == 0
render :update do |page|
// Bunch of updating code to the displayed message to
indicate no match found.
page[:name].visualEffect('highlight')
end
else
// This is where I try to test the code of
if @my_names[0].province == "XX"
// Then want to do some other things.
else
// Set sessions variables.
session[:var_a] = @my_names
session[:var_b] = @my_names[0].first_name
session[:var_c] = @my_names[0].last_name
session[:var_d] = @my_names[0].line_1
session[:var_d] = (@my_names[0].line_2 || '')
session[:var_e] = (@my_names[0].province || '')
----------
Any thoughts ? It doesn't seem to matter if I test AFTER the initial
test for 0 or before (knowing that I am going to get a match because of
predefined values that exist in the database.) I always get the same
error. Thanks again in advance.
