我正在开发一个JSF2/Primefaces应用程序,我在访问此组件的支持bean中复合组件的接口中定义的属性时遇到问题.
我的组件定义如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:composite="http://java.sun.com/jsf/composite">
<composite:interface componentType="testComponent">
<composite:attribute name="text" required="true" type="java.lang.String" />
</composite:interface>
<composite:implementation>
<h:outputText value="Passed text is: #{cc.attrs.text}" />
</composite:implementation>
</html>
它存储在名为text.xhtml:application/src/main/webapp/resources/my_componentdirectory 的文件中.
我在另一个页面(这是一个Facelets组合元素)上使用此组件,如下所示:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:myc="http://java.sun.com/jsf/composite/my_component"
template="./resources/templates/template.xhtml">
<ui:define name="content">
<h:form id="products">
<myc:test id="test" text="A text" />
</h:form>
</ui:define>
</ui:composition>
支持组件类定义如下:
package my.application.component;
import javax.faces.component.FacesComponent;
import javax.faces.component.UINamingContainer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@FacesComponent ( value="testComponent" )
public class TestComponent extends UINamingContainer {
Logger log = …
