我用的是Apache/2.2.14 (Win32) PHP/5.2.6 Yii Framework/1.1.0
修改了demos下示例blog的layouts里面的column2.php就出现问题了。
<?php if(!Yii::app()->user->isGuest) $this->renderDynamic($this->widget('UserMenu')); ?>
CController::renderDynamic()里面不能用CController::widget，那么怎么让$this->widget(‘UserMenu’)不被缓存？
注意查看renderDynamic的参数规范。你应该用：$this->renderDynamic(‘widget’, ‘UserMenu’);
看了一下API文档，按你说的用$this->renderDynamic(‘widget’, ‘UserMenu’);结果报错：Object of class UserMenu could not be converted to string
调试了一下，发现是因为CController::widget的返回值是CWidget类型的对象，看了API上写的也是。是不是这里不能用widget？Yii的demo blog里面UserMenu是从CPortlet继承的类。如果这里不能用widget，UserMenu类就是多余的了，要自己写个函数来返回UserMenu的html代码再在视图里用$this->renderDynamic()来调用了。还有好多其他的用widget的地方也都要改。这样写感觉结构好乱。有没有一个比较好的解决方案？
出错的call stack是怎样的？

我刚给widget()函数添加了一个参数。你可以试试：$this->renderDynamic(‘widget’, ‘UserMenu’, array(), true);
好了，这下完美了。非常感谢强的帮忙和解决问题的及时。Yii很好很强大！ 
这个方式源代码里或api里貌似都没有说明，能不能加上呀。这个真的很完美
顺便再问一下
假如我需要对“新闻详细内容页”进行页面缓存，但是我又想记录每次访问的点击量，请问如何是好？
正常情况下，action是这样的
function actionView() {
$model=$this->loadModel();
$model->incHit();//增加点击量
$this->render(…)
}
