问题描述

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应该显示所选节点。我不能使用相对id，因为p：ajax元素与organizationUnit组件不在同一个命名容器中。在这种情况下我需要使用绝对id。使用Firebug，组件的ID为 tabs：0：editorsGroup：4：editor3：accountWindowsContainer：organizationUnit 。不是：form：tabs：editorsGroup：editor：accountWindowsContainer：organizationUnit 组件的绝对id？

How do I determine the absolute id of the organizationUnit(from /webapp/resources/acme/organizationUnit.xhtml)? When I select a node from the tree, the organizationUnit should display the selected node. I can't use a relative id because the p:ajax element is not in the same naming container with the organizationUnit component. I need to use absolute id in this case. With Firebug the id of the component is tabs:0:editorsGroup:4:editor3:accountWindowsContainer:organizationUnit. Isn't :form:tabs:editorsGroup:editor:accountWindowsContainer:organizationUnit the absolute id of the component?

自定义：include配置如下：

custom:include is configured as follows:

<?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 { ... }

推荐答案


Isn 't ：form：tabs：editorsGroup：editor：accountWindowsContainer：organizationUnit 组件的绝对id？

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

只有当您从中删除 prependId =false时才会这样做< h：form> 如果您可以确保< custom：include> 实现 NamingContainer 。如果后者不成立，则需要从绝对ID中删除：editor 部分。

That's it only if you remove prependId="false" from the <h:form> and if you can assure that your <custom:include> implements NamingContainer. If the latter isn't true, then you need to remove the :editor part from the absolute ID.

这篇关于确定绝对id的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
