problem with choices for properties
Hei everybody!
I'm trying to learn isis and DDD, using the wicket viewer.
I have a class TransportDemand which has as a property a pickup destination and a delivery destination.
The Destination is again defined as a class.
The TransportDemands 'factory and repository' has an action newTransportDemand();
In order to give the user a choice for the pickup/delivery destinations I created a method
choicesPickup() in the class TransportDemand
But, in the UI there are no choices presented when selecting 'New Transport Demand'. Only 'null' is written.
When removing choicesPickup() and declaring the class Destination as @Bounded, the list of destinations is shown.
What have I done wrong? Some code fragments below.
Thank your for any help
Christian
---- TransportDemand.java
public class TransportDemand extends AbstractDomainObject implements Comparable<TransportDemand> {
private Destination pickup;
public Destination getPickup() {
return pickup;
}
public List<Destination> choicesPickup(){
return destinations.allDestinations();
}
.....
private Destinations destinations;
public void setDestinations(final Destinations destinations) {
this.destinations = destinations;
}
}
---- TransportDemands.java
public class TransportDemands extends AbstractFactoryAndRepository{
...
public TransportDemand newTransportDemand(
@Named("Pickup") Destination pickup,
@Named("Delivery") Destination delivery
)
{
final TransportDemand transportDemand = newTransientInstance(TransportDemand.class);
transportDemand.setPickup(pickup);
transportDemand.setDelivery(delivery);
transportDemand.setOwnedBy(currentUserName());
persist(transportDemand);
return transportDemand;
}
public List<TransportDemand> allTransportDemands(){
final String currentUser = currentUserName();
final List<TransportDemand> items = allMatches(TransportDemand.class, TransportDemand.thoseOwnedBy(currentUser));
Collections.sort(items);
return items;
}
---- Destinations.java
public class Destinations extends AbstractFactoryAndRepository{
....
public List<Destination> allDestinations() {
final List<Destination> items = allInstances(Destination.class);
Collections.sort(items);
return items;
}
}

nice one, Adam. I had misunderstood that the problem was with an action
parameter drop down.

Hi Adam,
that's it! :-)
Thank you very much for helping!

Christian,
I think what you're looking for is a method in your TransportDemands
factory like:
public List<TransportDemand> choices0NewTransportDemand() {
return destinations.allDestinations();
}
and then choices1... for the second argument.
This is how you tell an action where to get its choices as opposed to the
choicesPickups method you have in the TransportDemand class which tells an
"already created" instance where to get its choices.
Hope that helps.

Ah. You need to instantiate instances using
container.newTransientInstance(ClassName.class).

RE: problem with choices for properties
Posted by Christian Steinebach <Ch...@marintek.sintef.no>.
Hi Dan!
Thank you very much again. It seems if you can make
it to the point where you can 'Edit' an instance, the necessary services are injected
and you will get a drop down list.
The injections 'setDomainObjectContainer' and 'setToDoItems' etc.
are called when you edit an existing object but not when you try to allocate a new one.
That would mean, only if you make a property @Optional the choiceProperty() method will
be called (but only when editing the instance afterwards).
Maybe I'm completely on the wrong track here...?
Anyway, thanks to your suggestion it now works as expected with the autoComplete annotation, so my problem
is solved in a way. :-)
So long
Christian

Hi Christian,
Just coming back to you on this...
I added a new property to the quickstart archetype's ToDoItem [1], and it
seems to be working ok [2], [3], [4].
The only thing that might be a bit odd is the rendering of "(null)" when no
reference is set... perhaps that should simply be blank. Otherwise, seems
ok...

RE: problem with choices for properties

Hei Dan!
Thanks for your reply.
I created a repository on github
Everything is based on the ToDo example.
Two 'important' classes:
TransportDemand.java
Destination.java
TransportDemand has a Destination fro 'pickup'
and a Destination for 'delivery'. That's all so far. ;-)
https://github.com/chris58/TransportPlanner.git
mvn install
run the wicket viewer
install fixture
select New Transport Demand
list of Destinations is null when neither Bounded or Autocomplete is annotated to Destination class
Both @Autocomplete (when uncommented in Destination.java) and @Bounded work as expected.
Don't know whether that is a bug or I did something wrong. ;-)
Cheers
Christian

Hi Christian,
Welcome to the list, and thanks for trying out Isis.
>From a quick skim over your code, it doesn't look like there's anything
wrong, so you might have uncovered an issue with the Wicket viewer.
I do know that the autocomplete functionality works [1], [2], and this may
be a better UI experience anyway... so try that out too.
I'll take a look when I get a chance, but if you could also create a very
simple example test case on github, that'd be really helpful.
