If the initialState argument of createReducer is nil, then its actionHandlers are never called.

Consider the following code:

local Rodux = require(workspace.Rodux)

local testReducer = Rodux.createReducer(
	nil,
	{
		TestStringSet = function(state, action)
			print("TestStringSet was called")
			return action.string
		end
	}
)

local reducer = Rodux.combineReducers(
	{
		testString = testReducer
	}
)

local SetTestString = function(str)
	return {
		type = "TestStringSet",
		string = str
	}
end

local store = Rodux.Store.new(reducer)

store:dispatch(SetTestString("foo"))
print(store:getState().testString)

When I run this, only nil is printed. TestStringSet was called also wasn't printed, which means that the handler wasn't called.

When I change the initialState argument of createReducer from nil to any non-nil value ({} for example"), TestStringSet was called and foo are printed, in that order.

I stared at this for awhile, since it didn't make sense to me why this would happen!

This was fixed in #33, which probably wasn't in the last binary release for Rodux. You should be able to pull in the latest Git master via Rojo, but I'll go ahead and publish a new release as well.

Right, my bad. Should have occurred to me to test on the latest version of the code. Thanks for the new release!
