Description: When creating a new Firefox Account in Settings, Year of Birth

Repro Steps:
1: Update a Flame to 20141014040203

I see a SyntaxError in the debugger when I tap the COPPA date selector:

    SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data

When I trace the error in the debugger, it looks (at first glance) like the method is trying to JSON.parse an object (detail.choices) that has already been JSON.parsed, lines 195-196[1]:

    195    if (detail.choices) {
    196      detail.choices = JSON.parse(detail.choices);

It's odd that there's no guard clause here to ensure detail.choices hasn't already been parsed from text into an object. However, I doubt this is the actual root cause, since git blame tells me that this code hasn't been touched in a _long_ time (since october of last year).

Bisecting gaia now to pinpoint the regression.

Thanks very much, Joshua.

Using today's m-c build of gecko, I can confirm that gaia commit c0ad769 introduces the regression.

Digging a bit deeper, it looks like the select element's change event is being fired twice: first by AppWindowManager, then by SystemDialogManager, both in response to the same mozChromeEvent. Unfortunately, it looks like the intention is for SDM to catch the event first, based on this comment[1] inside the SystemDialogManager event handler code:

    SystemDialogManager.prototype.handleEvent = function sdm_handleEvent(evt) {
        case 'mozChromeEvent':
  -->     // Making sure app-window does not receive this event.

I added a couple of console.logs to the spots where AWM and SDM attach mozChromeEvent listeners, and it does indeed look like awm_start is called first, so presumably its handler is invoked first by Gecko.

It appears that what's actually happening is that the AWM is creating the select options window as a div with id AppWindow_1, but it is assigning it the wrong z-index, so that it's drawn underneath the fxa SystemDialog:

(inside the system app debugger, after clicking the select element in the fxa coppa screen):
  <  aw = document.getElementById('AppWindow_1')
  <  window.document.defaultView.getComputedStyle(aw).getPropertyValue('z-index')
  >  "6"
  <  fxaDialog = document.getElementById('fxa-dialog')
  <  window.document.defaultView.getComputedStyle(fxaDialog).getPropertyValue('z-index')
  >  "100"

Anyway, this is getting a bit deep into the system internals.

George, any sense of the best fix here? I suspect that you might want to adjust the load order of SDM and AWM, rather than simply reverting the commit that caused this regression. I'm happy to help out, if you're short on time and can describe the changes needed.

Sorry, it's my mistake. I think I should keep the same init order to prevent more regression coming.

Hi Alive,
in bug 1049439, I change the module initializing order which cause this bug. I think I should keep the same order as before to prevent hidden regression. 

could you check it? Thanks.
