  • Can you please unaccept the answer? Know it's weird to ask, but in Meta for a bug report, accepted answer should be a developer who actually fix the bug, or explain why it can't be fixed etc. Having it accepted might cause the team to ignore the bug report – Shadow Wizard Wearing Mask V2 Dec 2 '15 at 8:26
  • @ShadowWizard Oops, I've just unaccepted it. Thank you for letting me know. – unarist Dec 2 '15 at 8:35
  • No problem, hopefully devs will see this soon and fix. :-) – Shadow Wizard Wearing Mask V2 Dec 2 '15 at 8:38
  • @ShadowWizard I was a bit worried as well so I asked Oded about how answering would affect bug visibility for the team. – rene Dec 22 '15 at 11:29
  • @rene but the point here was that the answer was accepted, so common sense tells that it means the bug was handled. As it stands, it doesn't matter - this is just one another bug in the 6000-8000 bugs list that will be fixed in 6-8 years. (or not :)) – Shadow Wizard Wearing Mask V2 Dec 22 '15 at 11:46
  • Sure, good call @ShadowWizard – rene Dec 22 '15 at 12:11

That seems to be a bug in wmd.js

This line is wiring the click event to be only called one single time:

$(".js-post-editor input[type=checkbox][name=communitymode]").one("click", function () {
    return confirm(function (e) {
        return "Are you sure you want to make this post Community Wiki?" + e.blankLine + "Doing so will remove explicit ownership and you will no longer earn reputation for upvotes on it. Once saved, this option cannot be unchecked without moderator assistance."
            "blankLine" : "\n\n"

The jquery selector is .js-post-editor input[type=checkbox][name=communitymode]

When the page https://meta.stackexchange.com/questions/ask is served it already contains the answer box with the checkbox but is hidden:

<input id="communitymode-42" name="communitymode" type="checkbox" >

The WMD editor is however started twice, once for the question and once for the answer:

    function createEditor() {
            heartbeatType: '',
            bindNavPrevention: true,
            postfix: "-42", // for the question this is a ""
                onDemand: false,
                discardSelector: ".discard-question"

As the jquery selector for the checkbox doesn't take the postfix into account, it wires the click event two times, hence the confirmation box showing twice.

I think if the jquery selector in 02_EditorInitialization.js is changed to

 // community wiki can accidentally be enabled - inform users of this nuclear option
 $('#communitymode' + options.postfix).one('click', function () {  

it should work as designed.

Expect 6 to 8 units to get this patch pushed.
