useInput/onChange not working in initial useEffect.

[hereblur]

I'm trying to implement custom input using useInput.
The initial value of input come from other context. I try to use 'onChange' to update value of the input but it's not update value as expected.

However It's working if I delay a bit using setTimeout().

What you were expecting:
onChange inside useEffect should update value of input.

What happened instead:
onChange inside useEffect not update value of input.

Steps to reproduce:
Implemented as example code

const {
    input: { onChange, name, value },
    meta: { touched, error }
  } = useInput({ ...props, source });

  useEffect(() => {

    onChange(Math.random() * 99999);
    // This should update value of input when render.
 
    console.log("ONCHANGE CALLED [useEffect]");
  }, []);

We've fixed an issue about defaultValue in Edit views (#6272) in 3.15.2. Can you test it and report if it fixes your issue?
