T5 ASO & Services
How I'm suposed to get services inside an ASO?
I placed my DAO objects in services I didn't need any sesion so far, but at
a certain point I need an ASO the wich needs to make use of my DAO services.
btw I've notice an old post in wich the willing was the oposit; how to acces
the ASO from a Services, such is the destiny of frameworks: give
satisfaction to all needs....
Thanks and never mind !

Well I just wandered about serialization issues, but better for me if it's
not a problem, at the end I added my Service as a parametrer in the ASO:
MyASO.addproducttoChart(idProduct,MyServices)
{
Map<Integer,Product> _chartMap;
Product p=MyServices.getProductById(idProduct);
_chartMap.put(idProduct,p);
}
It is unclear for me how to inject those services in the
ApplicationStateCreator, and also which will be they time scope...in the way
I did I now that the service has been "freshly" injected in the page, but
really this I still don't get it full.
Thanks

What? It's not uncommon to have methods on an ASO. You can also inject
services into it when creating it if you use an ApplicationStateCreator.
The relevant docs on Application State has an example at the bottom.

oopss!
I think I missed the point
the ASO aplication state object is merely a container for sharing
information across pages and time it shall not have metods, so I'll do as
you say.
thanks again

Sounds good, if it's simply imposible to use services within ASO I'll do
that, but I found more natural the other way arround:
In the Page
_MyAso.addproductttoChart(id);
In the ASO
MyASO.addproducttoChart(idProduct)
{
Map<Integer,Product> _chartMap;
@Inject private MyServices _MyServices;
Product p=_MyServices.getProductById(idProduct);
_chartMap.put(idProduct,p);
}
Instead of
In my Page
@Inject _MyServices
@AplicationState _MyAso
_MyServices.AddProductToChart(idProduct,_MyAso.getMap());
And in services
......
MyServices.AddProductToChart(idProduct,map<Integer,Product>){
Product p=_MyServices.getProductById(idProduct);
_chartMap.put(idProduct,p);
}
It's basically the same but imho in the first model the separation of
responsabilities is higher and keeps the service DAO lean.
thanks for yor answer!

Of course, you'll have the went-to-null trouble even passing the bits
of data into your service as method args :)

Max,
What I do in my app is pass the relevant bits of ASO data into my
service methods as arguments. You could pass the entire ASO, but you
might risk having it go null on you if the ASO gets set to null
somewhere.
