Hi there,

I am using an existing module that has the following code:

 
   private static $required_fields = array(
        'Country',
        'State',
        'City',
        'Address',
    );

i am trying to extend the class so that the core module stays the same. I want to change the required fields in the extension to make city and address required. How do i do that?

All the private static variables are automatically part of the config system. You can read up on it here: https://docs.silverstripe.org/en/3.3/developer_guides/configuration/configuration/

Thanks...will have a look at it
