在JSF2中加载页面时重定向

标签： jsf redirect richfaces

我使用JSF2和RichFaces，我想在加载其他视图时更改我的视图，例如

<rich:panel rendered="#{MyMBean.necessaryToChangeView}" styleClass="passwordChangeReminder">... </rich:panel>

MyMbean中的恶意：

public boolean isNecessaryToChangeView() {
    if (myRequirement...) {
          FacesContext fc = FacesContext.getCurrentInstance();
          fc.getExternalContext().redirect(fc.getExternalContext().getRequestContextPath() + "/pages/changePass.jsf");                

          return false;
    }

    return true;
}

使用此代码我正在
