java - 确定绝对id

Question

如何确定organizationUnit的绝对ID(来自/webapp/resources/acme/organizationUnit.xhtml)？当我从树中选择一个节点时，organizationUnit 应显示所选节点。我无法使用相对 id，因为 p:ajax 元素与organizationUnit 组件不在同一命名容器中。在这种情况下我需要使用绝对 id。对于 Firebug，组件的 ID 为 tabs:0:editorsGroup:4:editor3:accountWindowsContainer:organizationUnit。 :form:tabs:editorsGroup:editor:accountWindowsContainer:organizationUnit 不是组件的绝对 id 吗？

custom:include 配置如下:

<?xml version="1.0"?>
<!DOCTYPE facelet-taglib PUBLIC
"-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
"http://java.sun.com/dtd/facelet-taglib_1_0.dtd">
<facelet-taglib>
    <namespace>http://acme.com/custom</namespace>
    <tag>
        <tag-name>include</tag-name>
        <component>
            <component-type>com.acme.custom.DynamicInclude</component-type>
            <handler-class>com.acme.client.custom.tags.DynamicIncludeHandler</handler-class>          
        </component>        
    </tag>   
</facelet-taglib>  

@FacesComponent("com.geneous.custom.DynamicInclude")
public class DynamicInclude extends javax.faces.component.UIComponentBase{ ... }

public final class DynamicIncludeHandler extends javax.faces.view.facelets.ComponentHandler { ... }

使用Mojarra 2.0.8。

Isn't :form:tabs:editorsGroup:editor:accountWindowsContainer:organizationUnit the absolute id of the component?

仅当您删除时才会出现这种情况 prependId="false"来自<h:form>如果您能保证您的<custom:include>实现NamingContainer 。如果后者不正确，那么您需要删除 :editor绝对 ID 的一部分。
