my ionic version is 1.0.1

this error appear when i have a ion-slide with more than one image and i switch between views (with cache: false). It appear randomly. it's not a blocking error but somethink crash view app.
not solution jet need help!

Same thing here. It's ionic-slide with ng-repeats inside of it that seems to causes this. I also have view caching turned off.

[gimox]

ok i found the solution.
It's a safari mobile bug related to angularJs.
To solve it we need to rewrite all code like this:

object.$$a = 5;

to this:

var __webkitAssign__$$a = '$$a';
object[__webkitAssign__$$a] = 5;

The npm repo has a fantastic utility that help us.

https://www.npmjs.com/package/webkit-assign
It rewrite the ionic bundle for safari bug and IT WORK PERFECT!.

Thanks that worked.

[gimox]

yeaaaa!

Is this still an issue with angular 1.4?

[mrtomrichy]

@mhartington I just encountered this issue and I updated to Ionic 1.1.0 with Angular 1.4 to see if it would fix the problem but it still persists on iOS8.4 iPhone 6 sim.

[mhartington]

So this is an issue still?
Could you provide a codepen to test against?

[gimox]

problem is here in ionic 1.1 and angular 1.4.*, patched as above in my post and it worked.

I am able to webkit-assign ionic bundle and it works just fine, but I am not able to get it to work with the minified version of ionic bundle. I get angular not defined.. @mrtomrichy , @gimox , any ideas?

[gimox]

follow this guide:

• http://blog.ionic.io/minifying-your-source-code/
• https://www.airpair.com/ionic-framework/posts/production-ready-apps-with-ionic-framework

you need some trick to minify angular.
