Has a problem using Navigator Controller, because I noticed when used conditions like ngIf or ngSwicht to alter an item by ion-list, ion-card and ion-grid, when I click in the back button on navigator is showing a error message Object Unsubscribed and stop the navigator controller.

Expected behavior:
In Ionic 1 this problem not exist, I'm starting use the latest version by ionic 2, I don't know if that this error exists in old version.

This issue should be fixed in the nightly release, to update:

npm install ionic-angular@nightly --save --save-exact

It will also be in the 2.0.0-rc.5 release. Please let me know if you still have an issue, thanks!

Hey @brandyscarney, sorry to say I just run into this error again on the latest nightly (2.0.0-rc.4-201701052314). I'm looking into it, I'll see if I can reproduce it in a minimal example.

Thanks @jsayol! Let me know when you do. I'll leave this issue closed and the other issue (#9751) open since this use case was fixed.

Oops, actually meant to comment on the other one.
