ionSwipe in beta 11 and data binding

[m5rk]

Short description of the problem:

Changes made to an item via (ionSwipe)="someFunction(item)" are not reflected as expected.

What behavior are you expecting?

I expected the modifications made as a result of swiping to be reflected in the page.

Steps to reproduce:

1. See this repo
2. Clicking the item toggles it. Swiping it does not.

insert any relevant code between the above and below backticks

Made a more minimal repo here with the latest nightly that shows that if you put the logic inside a zone.run() that it works. If the logic is not inside a zone.run it does not.

Also, i can confirm that this seems to be limited too "gesture" event emitters like ionSwipe and ionDrag

[m5rk]

@jgw96 Thanks for the zone.run(() => { ... } workaround. That allows me to get back on track with beta 11.

note to team: Seeing some really weird stuff with zone. The gif below shows everything.

The template variable that im changing to make *ngIf hide the button with the ionSwipe event does not cause the template to update and does not appear to run in zone. But, when i do something that does run in zone, like a click event, then the template gets updated (as you can see by the button disappearing).

@jgw96 the gif is not longer working. what is this issue about? sliding item?

[jgw96]

@manucorporat hmm the gif seems to be working for me still? This is about the (ionSwipe) event on sliding lists. It does not seem to run in zone properly.

I had the same issue with ionSwipe. I believe the gesture event is not running in the NgZone, so it's not triggering any change detection. But as soon as you're emitting a event in the NgZone like a click, the change detection triggers and the view is updated.

@m5rk @fknop fixed!
