Question

I have a model which throws a XMLDocument_Exception. In my controller action I want to include a try catch block which may throw this exception but for some reason it is not getting caught.

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');
    }
}

and the model is throwing the exception like so:

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

FedoraMETSPublication extends FedoraMETS which extends XMLDocument. The code above is in the constructor for FedoraMETS’s constructor.

I’m seeing the following error:

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

Why am I not catching this exception in my Action Controller?

Answer 1

Check the stack trace, #2:

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

Apparently, the exception is being thrown to the view, not to the controller. Use try...catch in the view (or change your approach).
