OpenXava 3.1.2, released recently, is a model-driven framework to develop Java Enterprise applications in an agile way: With OpenXava you provide only your POJOs annotated with JPA and you obtain an AJAX application ready for production.
The main new feature of this 3.1.2 release is the support for view inheritance. Although OpenXava generates a workable user interface from your naked JPA entities, you have the option to refine the produced user interface using the @View annotation. Just in this way:
@Entity
@View(name="WithSections",
members =
"name, sex;" +
"mainLanguage;" +
"experiences { experiences }"
)
public class Programmer {
Since version 3.1.2 you can defined a view extending an existing one. For example, you can reuse the WithSections view in a child class of Programmer:
@Entity
@View(name="WithSections",
extendsView="super.WithSections",
members =
"favouriteFramework;" +
"frameworks { frameworks }"
)
public class JavaProgrammer extends
Programmer {
As you can see, the way to extends a view of the superclass is using the super prefix for extendsView. In this case the WithSections view of the JavaProgrammer entity will have all the members of the WithSections view of Programmer entity plus its own ones.
Look the aspect of WithSections view of JavaProgrammer:
