Hi Gabriel, just tried your code with DomainService Categories
package dom.simple;
import org.apache.isis.applib.DomainObjectContainer;
import org.apache.isis.applib.annotation.DomainService;
@DomainService
public class Categories {
public Category newCategory(
String name,
Double price) {
Category aCategory = container.newTransientInstance(Category.class);
aCategory.setName(name);
aCategory.setPrice(price);
container.persist(aCategory);
container.flush();
return aCategory;
}
@javax.inject.Inject
private DomainObjectContainer container;
}
You can create negative price, since there is no validation in newCategory,
but when you open the object view, edit object and try to type negative
value, validation will work.
