I have a class ETSCustomer which decorates Member. (Actually, it's a subclass of EcommerceRole from the ecommerce module.)
It's registered like this in mysite/_config.php:
Object::remove_extension('Member', 'EcommerceRole');
Object::add_extension('Member', 'ETSCustomer');
And it seems to be working properly, except that it's requireDefaultRecords() method is not being called on /dev/build.
I'm not familiar enough with SS to know how methods are dispatched on /dev/build. Anyone have any thoughts as to why my method isn't getting called?
