[2.0.0-rc2] Can't get $refs correctly

[dalphyx]

Vue.js version

2.0 rc2

Reproduction Link

https://jsfiddle.net/1khxsgue/

Steps to reproduce

Just click run button, open console can find the error Cannot read property 'hello' of undefined

What is Expected?

The same code with 2.0 rc-1 https://jsfiddle.net/y35ot0du/ run without any error. We can access key testA inthis.$refs when components mounted hook is called .

@dalphyx, seems to me is behaving as expected. There is a v-if directive set to false which alters the component execution. At the moment of mounted the test component is not available.

The fact that it does not work in -rc.2 anymore probably has to do with this:

Fixed

Fixed vdom patch errors on components with empty root (e.g. when root has v-if or transition)

@yyx990803 Is that a bug ?

[miljan-aleksic]

@LinusBorg, if using v-if in a root node is forbidden, shouldn't it warn about when doing such?

[LinusBorg]

Already deleted that comment, that was not entirely correct.

@TomKaltz please open a separate issue, thanks.

Maybe this is the same issue with #6632
