Subject: Re: cgi class prints garbage in HTML output

Hi everybody

the correct (i.e. the code which creates the requested HTML code) ruby 
1.9.3 code for the requested result looks like:
NOTE: each ..collect do ... must be terminated by an ... end.join("")

<snip>
    nf = rf.length    # total number of fields to display
    noc = @sess["noc"].to_i
    nor = nf/noc  # total number of rows to display
    ncta = (CHARS_TEXTAREA / noc).to_s    # cols in the textarea
    if nrr == 1    # must be one single row
      @c.tablen("class"=>"ps") { "#{
        (0..nor).collect do |rct|
  # field names
      @c.tr{
      "#{ rf[rct*noc, noc].collect do |nf|  # field name
        nt = @dbx.tat[nf].to_s        # field type
        @sess["aeq"].include?(nf) ? nf = @sess["aeq"][nf] : nf = _(nf)
          @c.th("class"=>"tah") {"#{nf} (#{nt})"}
        end.join("")
      }"
      }+"\n"+
      @c.tr{
  # field content
      "#{ rf[rct*noc, noc].collect do |nf|  # field name
        nt = @dbx.tat[nf].to_s        # field type
        nr = rr[nf]          # field value
        if nf.match(/date_(next|last)_action/)
          nr = Time.now.strftime("%Y-%m-%d")
        end
        nx = CGI::unescape(nr)
        nrta = ROWS_NEW_TEXTAREA.to_s
        cmds[nt].call(ncta, nrta, nf, nx, nr)

        end.join("")
        }"
        }
        end.join("")
      }"+"\n"
      }

</snip>
