Really need to set value in hidden field programatically

Hi there, i can not find a way to set a value in a field, it is no bound to any onChange event, i just need to set a value. Ideally something like that <Field setValue={some-value} type="hidden" .../> Is there any way to achieve that? If not would anybody be able to point me to where I could add that functionality in the redux-form codebase if I fork it? Thanks a lot!

The component you have wrapped with reduxForm receives a change function in the properties: this.props.change('fieldname', new_value);

This is basically a hidden field. And also I think this would work in React v16 or never.

<Field
    name="name"
    val="John"
    component={({ input, val }) => input.onChange(val)}
/>
