Good afternoon.
I am trying to create a domain service with a method to finish a purchase.
So, I have to set in the purchase a list of items, and I don't know how I
do this.
I imagine the interface with a field to find items and a table or a list
showing the selected items by the user.
Any tips?
Thank you.

Yes, I am aware of this.
My doubt is how to create a form to persist an entity like the others, but
I need to persist such entity with a list of items.
My example is: an entity Purchase and many entities PurchaseItem. I need
that Isis renders a list or a table, something like this.
I don't know if I explained correctly. I hope so.
Sorry for my english.

See ToDoItems class in the Todo app demo.
It is a domain service and a repository for ToDoItem objects.
I think you need a Purchase repository for PurchaseItem objects.

It sounds like you want to obtain a reference to an existing domain object
(probably "Product" from your description) so that your new "Purchase" (or
"Order") object references it...
public class Order {
private Product product; // I'm guessing this is what needs to be set
private int quantity;
/// other fields
/// getters and setters omitted
So you could use an action to create, with an autoComplete supporting
method [1] for the appropriate action parameter , eg:
public class Orders { // the domain service
public Order createOrder(Product p, @Named("Quantity") int quantity) {
Order o = container.newTransientInstance(Order.class);
public Collection<Product> autoComplete0CreateOrder(String
productRefOrDescription) {
return products.findByRefOrDescription(productRefOrDescription);
@Inject private DomainObjectContainer container;
@Inject private Products products;
where Products is a repository for the Product class letting you locate
products by their reference or description.
