First round
My first try was #1025, I tried pass a default field state to updateField so that updateField can read initial value from given state.
But I forgot the the validate function which causes validate function cann't read initial values at first render.
Second round
My second try was #1061, I tried pass initial values to validate function. But I forgot a form may have no initial values or only have partial initial values which causes #1241.
Third round
I thought I can create a initial form state before creating fields, so that updateField and validate function can both read initial values.
