        上图中紫色的椭圆结点在ecore模型中代表Method，在属性视图中可见它的一些属性。如果要使TimeProperty属性值为"NONE"时，TimeUnit和Value值分别变为"NONE"和0.0，应该如下修改MethodItemProvider类中的notifyChanged()方法(紫色的代码是添加的，其他均为GMF生成的）：
    public void notifyChanged(Notification notification) {
        updateChildren(notification);

        switch (notification.getFeatureID(Method.class)) {
            case EventPackage.METHOD__PROPERTY_NAME:
         {
                //如果该项设置为NONE,那么TimeUnit和Value项应该分别设置为NONE和0.0
                Method owner = (Method)notification.getNotifier();
                TimeProperty newValue = (TimeProperty)notification.getNewValue();
                if(newValue.equals(TimeProperty.NONE))
              {
                    owner.setTimeUnit(TimeUnit.NONE);
                    owner.setValue(0.0);            
                }
             }
            case EventPackage.METHOD__VALUE:
            case EventPackage.METHOD__TIME_UNIT:
            case EventPackage.METHOD__CLASS_NAME:
            case EventPackage.METHOD__METHOD_NAME:
            case EventPackage.METHOD__PARAMETERS:
            case EventPackage.METHOD__RETURN_TYPE:
                fireNotifyChanged(new ViewerNotification(notification, notification.getNotifier(), false, true));
                return;
        }
        super.notifyChanged(notification);
    }
  MethodItemProvider类位于genmodel生成的edit项目中，它相当于Property View的ContentProvider。

    2.某个EReference如果多重性为"0...*",则在属性页中把lower bound设置为0，upper bound设置为-1。
    3.genmodel根元素的第一层子元素的属性页中，"All"类别中“prefix”属性值是指EMF生成的代码中Factory和Package等类的前缀，可以指定为模型名字，首字母大写以符合类名的习惯；“base package”属性值是生成的各个包的前缀，假设指定为“com.example"。然后有“Ecore”类别，其中的各个属性值是从ecore模型中读过来的，不可修改，其中“Package”类别下的"Name"属性值是包名的一部分（假设指定为model），接在前面的base package值之后，那么生成的Model 部分代码分别有三个包：com.example.model; com.example.model.impl; com.example.model.util. 
   btw：在有的GMF 版本中，如果包名存在首字母大写的单词，那么生成代码的时候会出错。
