Create an new class:

Jease/WEB-INF/src/jease/cms/web/content/editor/MeetingEditor.java

The life-cycle of an editor is handled by Jease in the background, so you don't have to worry about it:

• #init() is called to create the editor-form with the specified order of the fields.
• #load() is called to load the editor-form-fields with the corresponding values from the persisted (or newly created) content-object.
• #validate() is called to validate given values of the editor-form-fields.
• #save() is called to transfer values from the editor-form-fields back to the content-object.

You can get a reference to the current selected content-object via the method #getNode() from the ContentEditor.

package jease.cms.web.content.editor;

import jease.cms.domain.Meeting;
import jfix.zk.Datetimefield;
import jfix.zk.RichTextarea;
import jfix.zk.Textfield;

public class MeetingEditor extends 
                    ContentEditor<Meeting> {

 RichTextarea topic = new RichTextarea();
 Textfield location = new Textfield();
 Datetimefield start = new Datetimefield();
 Datetimefield stop = new Datetimefield();

 public MeetingEditor() {
 }

 public void init() {
  add("Topic", topic, "Please enter topic.");
  add("Location", location);
  add("Start", start);
  add("Stop", stop);
 }

 public void load() {
  topic.setText(getNode().getTopic());
  location.setText(getNode().getLocation());
  start.setDate(getNode().getStart());
  stop.setDate(getNode().getStop());
 }

 public void validate() {
  validate(topic.isEmpty(), "Topic required");
  validate(location.isEmpty(), "Location required");
  validate(start.isEmpty() || stop.isEmpty(),
     "Date required");
  validate(start.getValue().after(stop.getValue()), 
      "Date invalid");
 }

 public void save() {
  getNode().setTopic(topic.getText());
  getNode().setLocation(location.getText());
  getNode().setStart(start.getDate());
  getNode().setStop(stop.getDate());
 }
}

Please note: If you want to display a nice icon for your newly created content-type in the views of the Content-Management-System, you have to place an icon (PNG-format) with the same name as your content-type into Jease/WEB-INF/src/web/jease/cms.
