Bug: Checkbox values not restored when editing a form

See DebianBug:152766

Failed to include URL http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=152766 Protocol scheme 'https' is not supported (LWP::Protocol::https not installed) From: Jonathan H N Chin <jhnc%stone@newton.cam.ac.uk> Subject: twiki: need \Q...\E in TWiki::Form::renderForEdit To: submit@bugsPLEASENOSPAM.debian.org X-Mailer: bug Delivered-To: submit@bugsPLEASENOSPAM.debian.org

Package: twiki Version: 20011201-1 Severity: normal

I set up a TWikiForm like:

| *Name:* | *Type: | *Size:* | *Values:* | *Tooltip message:* |
| myfield2 | checkbox | 3 | [[MyWikiWord1][opt1]], [[MyWikiWord2][opt2] | |

and then attach it to a topic.

I edit the topic and set some checkboxes.

Once I have saved the topic, if I re-edit it, the checkbox values are "unset" regardless of what actual value was saved.

I have painfully traced this to TWiki::Form::renderForEdit which does not escape $item when it is used in the checkbox match:

if ( $value =~ /(^|,\s*)$item(,|$)/ ) {

This would be better written as:

if ( $value =~ /(^|,\s*)\Q$item\E(,|$)/ ) {

which would give the expected result (ie. checkboxes are selected).
