如何在Zend框架操作中捕获自己的模型异常

我有一个引发XMLDocument异常的模型。在我的控制器操作中,我希望包含一个try catch块,该块可能会引发此异常,但由于某些原因,它没有被捕获。

public function listissuesAction() {
    $publicationPid  = $this->_request->get('publicationPid');
    $this->getFrontController()->throwExceptions(true);
    try {
        $fedoraPublication = new FedoraMETSPublication($publicationPid);
    } catch (XMLDocument_Exception $e) {
        return $this->_forward('content/unavailable');
    }
}

模型抛出异常如下:

if ($mets) {
    $this->loadXML($mets);
} else {
    throw new XMLDocument_Exception('Failed to load METS Document from SOAP Server');
}

FedoraMETSPublication扩展了扩展XMLDocument的FedoraMETS。上面的代码在FedoraMETS构造函数的构造函数中。

我看到以下错误:

Fatal error:  Uncaught exception 'XMLDocument_Exception' with message 'Failed to load METS Document from SOAP Server' in    2 /Users/dof/Sites/ccymod/trunk/application/models/Fedora/METS.php:21

为什么我的动作控制器没有捕捉到这个异常?

检查堆栈跟踪,#2:

#2 /Users/dof/Sites/ccymod/trunk/application/views/scripts/browse/listissues.phtml(19): FedoraMETSPublication-&gt;getIssues()

显然,异常被抛出到视图,而不是控制器。使用 try...catch 在视图中(或更改您的方法)。
