Hi Thomas
Thanks for your reply with details. I am new in vaadin and still not successful, please don’t mind. I have modified the code as below and having the exceptions. I am also appending herewith the entities
Modified view
@CDIView("treetable")
public class TreeTableView extends MVerticalLayout implements View {
@Inject
AddressFacade af;
@Inject
CountryFacade cf;
TreeTable ttable;
private Set<Country> country = new HashSet();
@PostConstruct
public void initComponent() {
List<Address> a = (List) (Address) af.findAll();
List<Address> a2 = (List) (Address) af.findAll();
HierarchicalContainer container = new HierarchicalContainer();
// Initialize the container as required by the container type
container.addContainerProperty("city", String.class, null);
container.addContainerProperty("street", String.class, 0);
container.addContainerProperty("countryId", String.class, 0);
container.addContainerProperty("countryName", String.class, 0);
container.addContainerProperty("country", String.class, 0);
for (Address addr : a) {
for (Address addr2 : a2){
if(addr.getCity().equalsIgnoreCase(addr2.getCity())){
// Create an item
Object itemId = container.addItem();
// Get the item object
container.getContainerProperty(itemId, "city").setValue(addr.getCity().toString());
container.getContainerProperty(itemId, "street").setValue(addr.getStreet().toString());
container.getContainerProperty(itemId, "country").setValue(addr2.getCountry());
//container.setParent(container.getItem("street"), container.getItem("country"));
container.setParent(addr,addr2);
return;
}
container.setParent(addr, "");
}
}
ttable.setContainerDataSource(container);
// Expand the tree
ttable.setCollapsed(2, false);
for (Object itemId : ttable.getItemIds()) {
ttable.setCollapsed(itemId, false);
}
ttable.setPageLength(ttable.size());
addComponent(ttable);
//--------------------------
addLayoutClickListener(new LayoutEvents.LayoutClickListener() {
@Override
public void layoutClick(LayoutEvents.LayoutClickEvent event) {
}
});
}
@Override
public void enter(ViewChangeListener.ViewChangeEvent event) {
}
}
