I've following class defined:

public class User {

private String id;

//get,set, equals & hashCode method are defined

}

If I add more attributes using declare syntax as below:

declare User

    name : String

end

it gives error "Error creating field accessors for 'User' for type 'User'". Is there a way, more attributes can be added in existing class using declare syntax? 

Alternatively, if a class is created by using only declare syntax, can we add equals/hasCode methods dynamically?

Thanks & Regards,

Neel
