redux-form: How to disable submit button if at least one Field is not valid?

Question

I'm rendering the below simple form using redux-form and it's working nicely. Now, I'd like to have the submit button disabled in one more situation: If any of the Field's has an error (i.e. it's meta.error is set).

From lokking into the docs, I suppose it is not possible for the surrounding <form> to know if its <Field> components have an error. Maybe anyone has an idea, how to solve it as easy as using disabled={hasErrors || submitting || pristine}

const EditBlogEntryForm = ({ onSubmit, reset, handleSubmit,
                         pristine, submitting, ...rest }) => {
    console.log('rest: ', rest);
    return (
        <form onSubmit={handleSubmit(onSubmit)}>
            <div className="form-group">
                <Field name="title"
                    type="text"
                    component={renderField}
                    label="Titel"
                    className="form-control"
                    placeholder="Titel eingeben..." />
            </div>
            <div className="form-group">
                <Field name="text"
                    component={renderTextArea}
                    label="Text"
                    className="form-control"
                    placeholder="Textinhalt eingeben..." />
            </div>  
            <div className="form-group">
                <Field name="image"
                    type="text"
                    component={renderField}
                    label="Bild-URL:"
                    className="form-control"
                    placeholder="Bildadresse eingeben..." />
            </div>  
            <div>
                <button type="submit" className="btn btn-default"
                    disabled={submitting || pristine}>
                    Blogeintrag speichern
                </button>
                <button type="button" className="btn btn-default"
                    disabled={pristine || submitting}
                    onClick={reset}>
                    Formular leeren
                </button>
            </div>
        </form>
    );
};

Redux forms already passes lots of properties into the form. One is invalid. That's what I am using to determine if any of the field validations failed and then disable submit.

Don't abuse state you need just using this.props for each setState Component one more time will be render

const {invalid} = this.props

return(
<button type="submit" className="btn btn-default"
     disabled={invalid|| submitting || pristine}>
     Blogeintrag speichern
 </button>)
