Type: bug

Platform: all

See -> http://forum.ionicframework.com/t/back-button-missing-sometimes/28235/9

@yewnork - Its a BUG 😦

See this fork of your Plunker: http://plnkr.co/edit/JVvifeOX5VSDGoa8lrTJ?p=preview

I updated the Plunker to use 1-0-1 (http://forum.ionicframework.com/t/1-0-1-vanadium-vaquita-released/27420) which didn't work so I checked my bower.json and noticed that I am still using:

"ionic": "v1.0.0-rc.3"

which works, index.html:

<link rel="stylesheet" href="http://code.ionicframework.com/1.0.0-rc.3/css/ionic.css" />
<link rel="stylesheet" href="style.css" />
<script src="http://code.ionicframework.com/1.0.0-rc.3/js/ionic.bundle.js"></script>

Note: I also updated from href to ui-sref in several files + fixed 'menu.html' as well :)

Just tried:

"ionic": "v1.0.0"

Which works, but:

"ionic": "v1.0.1"

doesn't :(

I have same issue with version 1.0.1

Here is code pen demo. http://codepen.io/anon/pen/wamRVX4

Sequence to reproduce

1. Select Check in from side menu.
2. Click on Attendees on main page new page will display back button
3. Click back which will return to Check in page
4. Now select check in from side menu (Even if same page is open)
5. Click on Attendees link new page will not display Back button

Plunker Ionic 1.0.1: http://plnkr.co/edit/wzh9enXseYHfhakdxXhm?p=preview

Plunker "Playlists - Ionic v1.0.0":

@Robinyo so whats the difference between these two plunkrs?

This one, http://plnkr.co/edit/pGwucVrTBDxSvw6z092h?p=preview , works as expected.

[Robinyo]

That's correct, Plunker "Playlists - Ionic v1.0.0" - http://plnkr.co/edit/pGwucVrTBDxSvw6z092h?p=preview displays a '<' back button if you:

1. Tap 'Reggae'
2. Tap '<'
3. Tap 'nav-icon'
4. Tap 'Playlists' shows Playlist with a '<' back button

If you follow the same steps with the Ionic v1.0.1 Plunker - http://plnkr.co/edit/wzh9enXseYHfhakdxXhm?p=preview it displays a 'nav-icon' NOT a '<' back button.

So, the 'bug' was introduced in Ionic version 1.0.1.

[mhartington]

There's a small list of changes in 1.0.1, and only two that may be the culprit.

https://github.com/driftyco/ionic/blob/master/CHANGELOG.md#101-vanadium-vaquita-2015-06-30

[mhartington]

Okay, so cef6708 is the culprit, looking into a fix

@perrygovier I am still seeing this behavior in ionic v1.1.0 where eventually I will see this in the console:

TypeError: Cannot read property 'expire' of null

When using the menu-toggle attribute it is working fine.

This issue remains unresolved. Using Ionic 1.7.12. The error occurs in nextViewOption() in the deregisterStateChangeListener. When a $stateChangeSuccess event occurs it's handler is called. nextViewOptions is null when the event occurs which triggers the error at nextViewOptions.expire when calling $timeout().

nextViewOptions: function(opts) {
      deregisterStateChangeListener && deregisterStateChangeListener();
      if (arguments.length) {
        $timeout.cancel(nextViewExpireTimer);
        if (opts === null) {
          nextViewOptions = opts;
        } else {
          nextViewOptions = nextViewOptions || {};
          extend(nextViewOptions, opts);
          if (nextViewOptions.expire) {
              deregisterStateChangeListener = $rootScope.$on('$stateChangeSuccess', function() {
                nextViewExpireTimer = $timeout(function() {
                  nextViewOptions = null;
                  }, **nextViewOptions.expire**);
              });
          }
        }
      }
      return nextViewOptions;
    },

This occurs to me to, on Ionic 1.7.14.
