FormDataConsumer is not working with custom form name

[ashim-kr-saha]

What you were expecting:
FormDataConsumer should provide form data object with custom from name or where form name is not record-form.

What happened instead:
Returns an empty object.

Steps to reproduce:
Give custom form name inside TabbedForm

Related code:

class VoucherCreate extends Component {
  render() {
    return (
      <Create title="Voucher" {...this.props}>
        <TabbedForm form="my-custom-form-name">
          <FormTab label="Details">
            <TextInput source="voucher_no" />
            <ReferenceInput
              source="student_id"
              reference="students"
              perPage={5}
            >
              <AutocompleteInput optionText="name" />
            </ReferenceInput>
            <FormDataConsumer>
              {({formData, ...rest}) =>{
                console.log(formData); // Should print the form data
              }
            </FormDataConsumer>
          </FormTab>
        </TabbedForm>
      </Create>
    );
  }
}

Thanks for the report. That's feasible using redux-form's FormName component.
