本文介绍了部分页面渲染技术中的三个核心组件属性：autoSubmit、partialSubmit 和 partialTriggers 的使用方法。通过这些属性，可以实现页面的部分更新而无需重新加载整个页面。文中还解释了 Immediate 属性的作用。

The following are three main component attributes used in partial page rendering:

autoSubmit

When the autoSubmit attribute of an input component (such as inputText and selectManyListbox) or a table select component (such as tableSelectMany) is set to true, and an appropriate action takes place (such as a value change), the component automatically submits the form it is enclosed in. For PPR, you might use this in conjunction with a listener attribute bound to a method that will perform some logic when an event based on the submit is launched.

autoSubmit

When the partialSubmit attribute of a command component is set to true, the page partially submits when the button or link is clicked. You might use this in conjunction with an actionListener method that performs some logic when the button or link is clicked.

partialTriggers

The value of this attribute is the ID or IDs of other components. Use a space between multiple IDs. When those components are updated (for example through an autoSubmit), this component will also be updated. All rendered components support the partialTriggers attribute

linkUpdate.setValue(new　Date());

AdfFacesContext.getCurrentInstance().addPartialTarget(linkUpdate);

PartialTrigger will only update a section of the form - not the whole form. So, I'm not exactly sure where is the problem. As long as the other items on the page are outside of the panelGroup where the button is - they shouldn't be re-rendering.

Immediate ：把这个属性设置成True,他就会直接执行Action的方法，不执行一些get方法，不会读取一些必要的信息
