Thiswill cause the appropriate Locale to be set into the application,causing the proper ResourceBundle lookup.</p><h1>Custom Tags / Components</h1><p>The <code>MapComponent</code> component is driven by the <code>map</code>tag, and it keeps track of the the selected area on the map. It determinesthe selected area from the incoming request, and fires an<code>AreaSelectedEvent</code> whenever the selected area is changed. <code>AreaSelectedEvent</code>is an <code>ActionEvent</code>. A method binding reference expression tag attribute is used to reference a method in the backing file bean (imagemap), and that method listens for action events. The listener method <code>processAreaSelected</code>,receives the <code>ActionEvent</code> and sets the locale accordingly.<p>The <code>AreaComponent</code> component is driven by the <code>area</code>tag. It uses Javascript events to visually show the selected area, and it sendsthe identifier of the selected area as part of the request. This tag must benested within an <code><d:map></code> tag.</p><h2>JSP Attributes</h2><p>Attributes described below apply to map tag.Attributes can represent values directly or point to them via value bindingexpressions except for actionListener attribute that points to amethod reference. <table border="1"><tr><th>JSP Attribute Name</th><th>What it Does</th></tr><tr><td><code>actionListener</code></td><td>Method binding reference that refers to a method that sets the locale from information contained in the <code>AreaSelectedEvent</code>.</td></tr><tr><td><code>immediate</code></td><td>A flag indicating that the default ActionListener should execute immediately (that is, during the Apply Request Values phase of the request processing lifecycle, instead of waiting for Invoke Application phase). The default value of this property must be false.</td></tr><tr><td><code>current</code></td><td>This refers to the current selected area on the map.</td></tr></table><hr></body></html></h:form></f:view>?? 快捷鍵說明
