As far as I know a mutation in Vuex should be synchronous. Vuex.nextTick ends up being asynchronous if I understand it correctly. Does it make it agains the convention to use it in the mutation then? Could it break something?
I have tried doing it this way and it seemed to work fine, but I haven't tried going back to previous state with Dev Tools for example.
Just to let You know: I use nextTick to postpone some sorting to avoid doing it unnecessarily multiple times. Maybe You have some other solution to that issue? I know I could use an action istead of a mutation, but I wanted to change some actions I already have into mutations as it seems to be a better option for me, but they use this pice of code.
