Question

我正在尝试使用AJAX来更改我的页面内容并包含其他一些内容，但它只是不起作用。我尝试了很多不同的解决方案。我需要我的menuItem_Cursos调用托管bean changePage并呈现组件panelGroup_Target。当我尝试调试java它只是没有到达那里。请帮忙。

这是页面

                value="Estudos de Casos" />
            <rich:dropDownMenu id="dropDownMenu_Acompanhamento"
            label="Acompanhamento" value="Acompanhamento" mode="ajax">
                <rich:menuItem label="Acompanhamento por Estudante" />
                <rich:menuItem label="Acompanhamento por Estudo de Caso" />
            </rich:dropDownMenu>
            <rich:dropDownMenu id="dropDownMenu_Sobre" label="Sobre o Sistema"
                value="Sobre o Sistema">
                <rich:menuItem label="Mapa do Software" />
                <rich:menuItem label="Ajuda" />
            </rich:dropDownMenu>
        </rich:toolbar>
        <h:panelGroup id="panelGroup_Target">
            <rich:panel rendered="#{principalProfessor.page == 'listaCursos'}">
                <ui:include src="#{principalProfessor.page}" />
            </rich:panel>
        </h:panelGroup>
    </f:view>
</h:body>
</html>

这是我的java代码：

package magicBeans.professor;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.event.ActionEvent;

import classesBasicas.Curso;
import classesBasicas.Pessoa;

import fachada.Fachada;
/**
 * @author Jesus
 *
 */
@ManagedBean(name="principalProfessor")
@ViewScoped
public class PrincipalProfessorBean {

    @SuppressWarnings("unused")
    private static Fachada fachada;

    private Pessoa usuarioLogado;
    private Curso curso;
    private String page = "";  

    public PrincipalProfessorBean(){

        fachada = Fachada.getInstance();
    }

    /**
     * @return the usuarioLogado
     */
    public Pessoa getUsuarioLogado() {
        return usuarioLogado;
    }

    /**
 * @param usuarioLogado the usuarioLogado to set
     */
    public void setUsuarioLogado(Pessoa usuarioLogado) {
        this.usuarioLogado = usuarioLogado;
    }

    /**
     * @return the curso
     */
    public Curso getCurso() {
        return curso;
    }

    /**
     * @param curso the curso to set
     */
    public void setCurso(Curso curso) {
        this.curso = curso;
    }

    public String getPage() {  
        return page;  
     }  

     public void setPage(String page) {  
        this.page = page;  
     }  

     public void changePage() {  
        page = "listaCursos.xhtml";
        System.out.println("AJAX PEGOU!");
     } 

}

感谢Chrome上的chrome（ctrl + shift + j），控制台告诉它需要一个带有ajax的表单。 =]

Ajax不支持richfaces
