@nextcloud/javascript

and/or perhaps @nextcloud/contacts

I can confirm This Bug with NC12, IE11, nginx on Centos7.

[jacestk]

same thing here with Centos7!
Someone can tell me what apps/modules is generating this list? I will try to patch it

[herrfeuer]

@jacestk start searching in contactmenu.js. i tried to switch back to that version worked in nc11 but no success.

[jacestk]

Yep thanx, found it after some reseach... line 296

_onSearch: _.debounce(function() {
			this.trigger('search', this.$('#contactsmenu-search').val());
		}, 700),

if you replace the timer value "700" by "5000" for example, the list appears but the research don't work anymore until the end of the time.
So the problem is from the trigger or _debounce function... Have to investigate a bit more...

[jacestk]

here my awful patch:

	_onSearch: _.debounce(function(){
			if (this.fixie11 !== this.$('#contactsmenu-search').val() ) {
				this.fixie11 = this.$('#contactsmenu-search').val();
				this.trigger('search', this.$('#contactsmenu-search').val());
			}
		}, 700),

Another problem appears: the first time you click onto the contacts icon, the list is "empty" (only a empty div is sended). Still working on it

@ChristophWurst mind having a look? ^

[ChristophWurst]

Found it: we're focussing the input field after rending the list of contacts. Since IE11 apparently has a bug where it triggers the 'input' even whenever a input gets focus, this causes an endless loop. Looks like M$ doesn't care about the bug and it's not being fixed: https://connect.microsoft.com/IE/feedback/details/810538/ie-11-fires-input-event-on-focus

However, I think I can add a little fix to this. Won't be the best UX, but it will at least not keep reloading all the time …
