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;
}
