Dynamic namespaces in binding helpers (mapState, …)

[ThomasKientz]

What problem does this feature solve?

With this feature we can use a prop for setting a namespace :

...mapState(this.namespace, ['filter'])

Actually we got the error :

Cannot read property 'namespace' of undefined

In my app I am dynamically registering store modules with generated on the fly namespaces. And I am passing the namespace as component properties.

Right now I have to do :

filter() { // more verbose but working
      return this.$store.state[this.namespace].filter
}

which is more verbose.

What does the proposed API look like?

...mapState(this.namespace, ['filter'])
