@marshare I do not think you understand my problem。

@qbaty @click.self="add"

@qbaty Thanks for rteporting this, looks like a bug indeed!

I took the freedom to correct the Vue version in your OP, as you use 2.1.6, noch 2.0.3

@LinusBorg Okey first I met this bug when I am using vue 2.0.3,and I try to update vue to the lastest version. this bug still exsit, so ... version should be 2.x

Seems fixing this bug created a new bug for :checked="" binding when using in combination with vuex states for maintaining checkbox states.

<template>
	<ul>
		<li v-for="option in visibleOptions" :key="option.value">
			<input
				type="checkbox"
				:name="filter.key"
				:value="option.value"
				:checked="inArray(option.value, filter.active)"
				@change="updateFilter">
		</li>
	</ul>
</template>

In this code example is :checked set to true or false whenever it's in the active filter array.
It seems when this component is updated (via vuex) the :checked stated doesn't get's updated like in 2.1.6. In my application is the state managed almost totally by Vuex.

Vue.js version

2.1.7+

Reproduction Link

Howto reproduce

When selecting several checkboxes (like brands) and use your browser back button to fallback to previous states. (it's managed by the popstate event)

What is expected

The checkbox will go on or off depending on the previous action.

What is actually happening?

Everything get's correctly updated (value wise), except the checkbox isn't honored to update (checked true/false). It keeps in a previous state. When selecting multiple after eachother and navigating back and forward is looks like is off a beat and missing the last changed checkbox.

Code that goes with it:
https://github.com/Automotivated/vroom/blob/master/src/views/elements/filters/Multiple.vue

While reading the docs in Vuex, it seems to be best practise to do it like I did.

When did it work

It worked like a charm in 2.1.6. Seems really that fixing this bug triggered this bug to be created.

@FKobus Please open a new issue instead of adding to the bottom of closed ones. Thanks!
