Transition Error: Cannot read property 'getTransitionName' of null

[TheMohanraj]

Ionic 2, IOS issue. Reproducible in desktop browser too.

Steps:
First I need to navigate more than 2 levels, then come back by pressing back instantly (regular speed) and you will get empty black screen in desktop browser or white screen in ios app.

Error stack:
nav-controller-base.js:289 Uncaught TypeError: Cannot read property 'getTransitionName' of null

@Dheran can you test if the problem persist in nightly?

npm install ionic-angular@nightly --save

@manucorporat I've never seen this stack trace when the black screen occurs in reference to #8885. I'm able to reproduce this in the browser and on iOS

Testing ionic-angular@nightly now

**Edit
Issue does not seem to be reproduceable in ionic-angular@nightly... so far.

I ran into this issue as well. However, as @curtisblanchette points out, after upgrading to ionic-angular@nightly, the problem doesn't occur anymore.

I will keep monitoring it...

[manucorporat]

I will close this issue for the moment. please feel free to reopen it.

I installed ionic-angular@nightly module. But to me it does not work, the problem persists. What could I do wrong?

[boye]

Alas, the problem persists indeed. I applied a different work-around for now.

I was getting a similar issue too with the same stack trace on rc.1. Seems to be fixed with nightly so far.

Hi Ionites,Did this fix the problem?
I installed ionic-angular@nightly module ,the problem persists in my project .
I want this problem to be definitely fixed!!!

Odd because it works for me using ionic-angular@2.0.0-rc.1-201610241941 but not the normal rc.1 release when I nav in and out of my views. Not sure why.

@TongeJie thanks for the repo! I will check it out this week! Reopening!!

Navigation bugs are top priority for us, we want to release a RC2 with a very stable navigation. We are adding a lot tests and asserts across the whole code base:

#8951
#8927

[manucorporat]

@TongeJie I was able to reproduce the problem with your repo, then noticed it does not use nightly:

    "ionic-angular": "2.0.0-rc.1",

UPDATE: after upgrading to nightly, I can not longer reproduce this issue with your repo

[jgw96]

After some testing with the conference app running the latest nightly I also cannot reproduce this issue anymore. Because of this I am going to close this issue for now. Thanks everyone!

Hi, I'm currently getting this error (rc3), I suspects it's some sort of race condition where using Loading.

**Edit: it's nothing to do with Loading, it's when you dismiss a modal using navController.pop() **

**Edit 2: using viewController.dismiss() (which is the right way to dismiss a modal) fixes this. Still, it probably shouldn't crash with .pop() **
