Dear community.
I'm having some problems when I'm trying to inherit exportasJSON.
I'm extending module.Order, this worked for almost every method but this is not working.
I've tried:
this._super.apply(this,arguments);
and:
this._super();
But it displays some errors:
Uncaught TypeError: Cannot call method 'apply' of undefined
and
Object [object Object] has no method '_super'
Someone know why this is not working? I'm trying to add some variables to return when it calls exportAsJSON.
Thanks
