Re: trying to avoid code bloat

[Barry Books]

I would not use an Abstract page for this purpose. The first problem is
protected will not work because the pages will not have the same package. I
would create a service with these services and just inject that. So your
page would just have

@Inject
private Services services;

and your service will have a constructer and get methods:

class Services(Service1 service1, ...) {
this.service1 = service1;
}

public Service1 getService1() {
return service1;
}

 Hi Folks,

 Can i construct an abstract page and inject a bunch of services and then
 have derived instances extend from that ?

 I tried it and seeing some weird class format errors.

 I did it with my model entities.

 trying to do it with pages and injectables.

 public abstract class AbstractPage implements

stick them in the base package, extend the class and it works great

Thanks Joakim... I noticed that. I didnt believe the error... but its good to 
have a confirmation.

I will try it again in that pages dir.

Base-classes need to be located in a package called base on the same level
as pages, components, mixins and services.
