scrollView is null when switching off of tabs view

[revie]

I'm running into an issue with today's release of Ionic (1.0.0-beta.12) that I wasn't experiencing with older versions. In my app, when navigating away from a view that has tabs, I've started getting this error show up:

Error: scrollCtrl.$element is null .link/<@lib/ionic/js/ionic.bundle.js:41174 Scope.prototype.$broadcast@lib/ionic/js/ionic.bundle.js:20368 Scope.prototype.$destroy@lib/ionic/js/ionic.bundle.js:20026 updateView@lib/ionic/js/ionic.bundle.js:42420 directive.compile/</eventHook@lib/ionic/js/ionic.bundle.js:42397 Scope.prototype.$broadcast@lib/ionic/js/ionic.bundle.js:20368 $StateProvider/$get/transitionTo/$state.transition<@lib/ionic/js/ionic.bundle.js:33645 qFactory/defer/deferred.promise.then/wrappedCallback@lib/ionic/js/ionic.bundle.js:18979 qFactory/ref/<.then/<@lib/ionic/js/ionic.bundle.js:19065 Scope.prototype.$eval@lib/ionic/js/ionic.bundle.js:20089 Scope.prototype.$digest@lib/ionic/js/ionic.bundle.js:19901 Scope.prototype.$apply@lib/ionic/js/ionic.bundle.js:20193 done@lib/ionic/js/ionic.bundle.js:15805 completeRequest@lib/ionic/js/ionic.bundle.js:16010 createHttpBackend/</xhr.onreadystatechange@lib/ionic/js/ionic.bundle.js:15953
ionic.bundle.js (line 17470)

and then, instead of going to the page I've selected, I'm instead sent to the last tab on my current view. I'm also occasionally getting this error:

Error: scrollView is null @lib/ionic/js/ionic.bundle.js:39362 timeout/timeoutId<@lib/ionic/js/ionic.bundle.js:21691 completeOutstandingRequest@lib/ionic/js/ionic.bundle.js:11901 Browser/self.defer/timeoutId<@lib/ionic/js/ionic.bundle.js:12202
ionic.bundle.js (line 17470)

but can't see yet how this one is triggered, though does seem to be related.

It seems like this is a result of changes implemented due to issue #1993, but I can't be certain. The only change I have in my app from the working version of Ionic I was using (1.0.0-beta.11) to this one was an implementation of the "expose-aside-when" addition to the side menu, but removing that option doesn't seem to solve the errors being thrown.

I'm sure a Codepen can probably explain this much better than I did. I'll work on setting one up.

Just open the side menu and click "Settings". You should end up on the "Account" tab. Click "Settings" again sends you to the right page.

Also experiencing this bug.

Realized that the Codepen I provided only shows the second error I reported. First error, although related to scrolling and tabs, seems to be specific to the "ion-infinite-scroll" functionality.

This codepen explains the problem a little better:

Scroll errors seem to occur:

• When going to a detail view from an infinite scroll view
• Moving away from a view that has an infinite scroll
• Switching away from tabs view to another page (both infinite scroll view and basic)

Hope this helps.

I've made some updates to the nightly build to fix these errors:

Would you be able to test out 1.0.0-beta.12-nightly-452 or greater and let me know if it fixes your issue:

Additionally, your example helped me find another bug which was hurting performance and not allowing your app to work correctly:

Please let me know how its working, and thanks for creating the issue.

Adam,

Oooh. Very nice! Love how elegant your change is.

Works perfectly. Thank you so much!
