action.error cannot be set when Error object returned in payloadCreator

[ypxing]

The behaviour has been changed by below commit

b9d5eb7

But we do depend on the original behaviour so that some basic validation can be done in our payloadCreator and set "error" for invalid cases.

Should we revert above commit back?

Can you do the validation outside the payload creator, passing in an Error object only when validation fails?

Also, would #136 fix this for you?

Thanks @yangmillstheory

Yes, I believe #136 should fix the issue since it will check the return value of payloadCreator.

I put basic validation in my action creator since I don't wanna write another wrapper.
