Sven, thank you.
I had a look at the Ajax example. I think you mean that I need to use
the PanelDetails class as a model, and create all the properties in
it. This is very verbose as the Product class contains many fields
that I need to edit, and adding getters/setters to the PanelDetails
class will make it big, and the code is repeated.
Based on the example, my class should be:
public class ProductDetails extends Panel {
@EJB
private ProductServicesLocal productServices;
private Product product;
public ProductDetails(String id, Product product) {
super(id);
setOutputMarkupId(true);
this.setCurrentProduct(product);
add(new Label("id"));
add(new AjaxEditableLabel<String>("codProduct"));
add(new AjaxLink<String>("save") {
@Override
public void onClick(AjaxRequestTarget target) {
System.out.println("saving product .... ");
}
});
}
public void setCurrentProduct(Product product) {
this.product = product;
setDefaultModel(new
CompoundPropertyModel<ProductDetails>(this));
}
public void setCodProduct(String codProduct) {
this.product.setCodProduct(codProduct);
}
public String getCodProduct() {
return this.product.getCodProduct();
}
}
This brings up a question, what is the best way to wrap domain objects
in a Model for easy CRUD and with a minimum amount of coding, and
reusing the component (ie, without having to recreate the object) ?
