I think you are using it wrong.

<el-select :value="value" @change="update">

To bind a variable to Select, one should use v-model, not :value. And, inside the update method:

update: function (selected) {
  value = selected
}

I wonder what the purpose of this callback is. Because selected always equals to value when the change event fires. Besides, to access value, one should use this.value. A working demo: https://jsfiddle.net/hq4scjto/4/

Also, 1.0.3 doesn't work perfectly in this case: https://jsfiddle.net/hq4scjto/5/ . You can see from the console that this.value never changes.

Sorry but I'm using vuex andv-model simply does not work in this scenario. As far as I know v-model is just a syntactic sugar to binding a value along with a change event so I was expecting this to work and it actually did. I was using the @change event and it worked perfectly with vuex mutations. Same for :value with vuex getters. 1.0.4 broke it for sure. So is it something that you would be willing to take a look at?

Regarding your example with 1.0.3 this.value never changes because , just like in my first jsfiddle, value was out of scope. Please take a look at this https://jsfiddle.net/6Lccqqfp/1/ and see that it actually works in 1.0.3. Same is impossible with 1.0.4 or 1.0.5. The @change event is just not triggered - and that is the only thing that's been broken.

In this case, try changing change to input: https://jsfiddle.net/hq4scjto/6/
Select without v-model should not fire change event (it's actually a bug if versions prior to 1.0.3 does). #1508 talks about a similar scenario.

It makes sense now. Swapping change to input works like a charm. Thanks for your help.

My input will be triggered,But when the input triggers the update of the data source,Value is not re-rendered
