Can't make something on Isis
Hi, I am with a problem trying to implement something on Apache Isis.
Here is what I want to do:
I have a class Country that has a String with the name of the country. Also
I have a class called Client which represents a client with the following
variables: String name, String surname, String address, Country country. I
made the setters and getters for all the properties. I also have the
classes Countries and Clients. Both of this classes have the methods create
and listAll. My problem is: I want to create a new Client and when I create
it, I want to have a select with the countries that I already persisted.
The problem is that I can't achieve this. I send the classes done on
attachment to understand how I am doing it. But basically is that what I
want, that when I create a new client, this one has a name, surname and
address to complete and a select with the countries that I already
persisted.
Thank you

Hi juan,
Could you direct these questions to users@i.a.o mailing list, please, and
I'll answer there.
Thx
Dan
PS: I don't think the apache mailing list servers allow attachments, but
you could always upload eg to imgur.com and provide a hyperlink.

Thanks for the feedback. We're constantly working to improve our
documentation, and we always provide help via the users@i.a.o mailing list
(cc'ed).
But also, remember this is an open source community. If you think
something can be improved, and you have the time to do so, then please
contribute. Doesn't need to be code... docs also work (as do raising
bug/feature requests). In this way the product gets better for all.

There isn't an up-to-date one, no. Apache Isis has grown from the
combination of the original Naked Objects Framework plus a number of
"sister" projects that I wrote for a book, Domain Driven Design using Naked
Objects Framework (2010). That book is now out of print, but possible to
obtain. It'll provide useful context even if none of the code in it runs.
See [1]
The other book still around is Naked Objects 2002. That'll give even more
insight into some of the original thinking/motivation of the framework.
But, as I say, if what you want is up-to-date answers as to how to achieve
something, then ask on users@ or look at our documentation page [2]

Our direction is to build on the REST API provided by our Restful Objects
viewer [1], which implements the RO spec [2]. The intent is then for
client-side Javascript apps to consume this API. The "next-gen" Isis
viewer will probably be written in AngularJS or similar.
I'm guessing that XavaPhone looks more like a PhoneGap'd webapp? It would
certainly be possible to adapt and reskin the Wicket viewer to support
this, but it would probably take a good few weeks working full time to do
so... Not on the roadmap for me.
Going back to RO client apps, last year we had two Google Summer of Coders
write generic viewers against RO. One was a native Android viewer, the
other was PhoneGap/JQueryMobile. Both would need some tidy up, but the JQM
one is most similar to OpenXava (albeit a different architecture); see [3]

Hi Juan,
(two requests: could you send just to users@ rather than to both users@ and
also dev@; also could you subscribe to users@ so that I don't have to
approve your posting and can make sure you get any replies. Thanks).
OK, this is easy to achieve enough to achieve. Several ways to accomplish
it, in fact.
given:
public class Clients {
public Client create(final @Named("Nombre") String name, final
@Named("Apellido") String surname, final @Named("Direccion") String
address, final @Named("Pais") Country country) {
final Client client = newTransientInstance(Client.class);
client.setName(name);
client.setSurname(surname);
client.setAddress(address);
client.setCountry(country);
persist(client);
return client;
}
...
}
Option 1 [1]: if the list of Countrys is bounded and immutable (which it
probably is), then just add @Bounded as an annotation to Country class:
@Bounded
public class Country { ... }
~~~
Option 2 [2]: if the list of Countries is the same in every context, but
is quite long and you want to filter by name, then provide an autoComplete
repository method:

public class Country {
...

public class Countries {
...
@Hidden
public List<Property> autoComplete(String searchPhrase) {
return ...
}
}
~~~
Option 3 [3]: if the list of Countries varies by context, and you don't
want to filter by name, then provide a supporting choices method:
public class Clients {
public Client create(final @Named("Nombre") String name, final
@Named("Apellido") String surname, final @Named("Direccion") String
address, final @Named("Pais") Country country) { ... }
public Collection<Country> choices3Create() {
