Hi community,

I tried to implement the ToDo demo but don't get things done. I think the main code snippets are the controller and the zul file which I have attached below.

Can anybody of you tell me how the demo can be make running?

TIA

Stephan

// Controller -------------------------------------------------------------
package events;

import java.util.List;
import java.util.UUID;

import org.zkoss.zk.ui.util.GenericForwardComposer;
import org.zkoss.zul.Button;
import org.zkoss.zul.Listbox;

import groovyjarjarantlr.debug.Event;

public class EventController extends GenericForwardComposer {
private static final long serialVersionUID = 1L;

private Button btn_add;
private Button btn_update;
private Button btn_delete;
private Listbox listbox_events;

private EventDAO evtdao = new EventDAO();

public List<ToDoEvent> getAllEvents() {
return evtdao.findAll();
}

public void onClick$btn_add(Event event) {
// insert into database
ToDoEvent newEvt = new ToDoEvent(UUID.randomUUID().toString(), current
.getName(), current.getPriority(), current.getDate());
evtdao.insert(newEvt);
}

public void onClick$btn_update(Event event) {
if (listbox_events.getSelectedItem() != null) {
// update database
evtdao.update((ToDoEvent) listbox_events.getSelectedItem().getValue());
}
}

public void onClick$btn_delete(Event event) {
if (listbox_events.getSelectedItem() != null) {
evtdao.delete((ToDoEvent) listbox_events.getSelectedItem().getValue());
}
}

ToDoEvent current = new ToDoEvent();

public ToDoEvent getCurrent() {
return current;
}

public void setCurrent(ToDoEvent current) {
this.current = current;
}
}
