A literal '+' in a value passed to the formula in formlink is converted to a space in the form field.

I only tried this using the default mode of operation of formlink, which passes the formula parameter in the URL (GET). The problem is that the + character in the URL is sometimes interpreted as a space by CGI applications. For example, the #urlencode parser function converts spaces into +s for URL encoding!


Here is the code that causes problems:

{{#formlink: TNAME
 | Add a Link
 | link
 | TNAME[fields]={{PAGENAME}}
}}

It works to link instances of 'TNAME' to the current page, however, because the '{{PAGENAME}}' gets changed (when it contains a +), the resulting link is broken.
