Subject: Problem with null field. Plz help!

Hi all.

Could someone please help me diagnose what might be wrong with this code snippet (taken from within a program) that cropped up after I upgraded from Ruby 1.68 to 1.8. The problem is that the Ruby crashes with this message:

	autogen.rb:301:in `initialize': Permission denied - ./boiler_install_notes/ (Errno::EACCES)
		from autogen.rb:301:in `open'
		from autogen.rb:301
		from autogen.rb:92:in `foreach'
		from autogen.rb:92
	>Exit code: 1

What's weird is that the crash happens when field[5] should be nil -- the entire if/end should be skipped. (If I insert a line # 297 puts field[5], console just shows does a line space as all puts do. No space or tab appears there.)


298	if field[5] != ""
299		if FileTest.exist?("./boiler_install_notes/#{field[5]}" )
300			install_note = ""
301			File.open("./boiler_install_notes/#{field[5]}") { |f| install_note = f.read.strip }
302			content2.gsub!(/<start_note_2>/, install_note)
303			puts "start_note_2:  #{field[5]} added."
304			outf.puts "start_note_2:  #{field[5]} added."
305		else
306			# Warn if note file specified in field[5] doesn't exist. 
307			puts "start_note_2:  #{field[5]} doesn't exist"
308			outf.puts "start_note_2:  #{field[5]} doesn't exist"
309		end
310	end


Thanks!
