Chaining actions and waiting for state updates?

[SaphuA]

What is the recommended way to chain actions where the second action is dependent on the first action to update the state?

For example. Selecting a country in a dropdown and then fetch a list of cities once one is selected.

This obviously doesn't work.

    selectCountry: (state, actions, country) => {
        actions.readCities();
        return { selectedCountry: country };
    },
    readCities: (state, actions) => {
        state.selectedCountry; // etc...
    }

The workaround I use now is to make country an optional argument of readCities, but I feel this is making the code needlessly complex. Especially with larger/complexer stores/actions.

    selectCountry: (state, actions, country) => {
        actions.readCities(country);
        return { selectedCountry: country };
    },
    readCities: (state, actions, country) => {
        country = country || state.selectedCountry; // etc...
    }

I came here with a similar question. Did you solve this? @didierfranc can you offer any insight?
