/* Automatic incremented ID based on a prefix and a @@ as a pattern for
* an automatic increased number.
*
* e.g.: neu.txt
* <form>
* Action template template:bug: bugs :
* Thanks "For submitting the bug"
* Textbox "Description" "/^[^\/:]+$/"
* autoid "BUG-ID" "=BUG-@@" "/^[^\/:]+$/" @
* Submit "Send"
* </form>
*
* with template: start.txt
* ====== @@BUG-ID@@ ======
* @@Description@@
*
* The autoiid field BUG-ID contains a template BUG-@@.
* 'BUG-' is used as prefix for all new pages.
* '@@' is replaced with an incremental number based on existing namespace/directory names.
* e.g. BUG-1, BUG-2, BUG-15 esxist then a new page gets BUG-16 as pagename.
*
+* Changes dev@aboehler.at, based on post in DokuWiki Forum (https://forum.dokuwiki.org/thread/7620)
+*
+* - Fixed refresh problem by adding a token to each request and remembering in
+* the metadata if the token has already been used - quite a hack
+*
+* - Fixed renderfield() to really add the hidden element.
+*
+* - Made code a bit more readable
