Good point. It should help with my enlightenment, as well as make it easier for others to see and comment. I've stripped out what is clearly not relevant, and left just bits of the global block and the subroutine. It does still reflect the issue. Error log complains about some undefined $term in a print statement, which is ok. In an example where I see the issue, the source code of the rendered page has
<!--bless({ ".charset" => "ISO-8859-1", ".fieldnames" => {}, ".parameters" => ["exec", "table", "orderby"], ".r" => bless(do{\(my $o = 94308584056848)}, "Apache2::RequestRec"), "escape" => 1, "param" => { exec => ["list"], orderby => [2], table => ["users"] }, "use_tempfile" => 1,
<!-- variables (index, desc) are (10, 1) -->
which would have been correct from a previous instance. The CGI:

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
