[fw-db] Problem with toArray logging a fatal error to the screen instead allowing catch to get it.

I have a function that calls a table object to return a rowset. The
code results in a fatal error thrown up on the screen instead of
allowing me to gracefully handle it.

Below is a code example.

The variable $id is a umber for the article I am trying to pull up.
if $id is a number that there is no record for in the database then it
will crash.

try {
$this->view->mainArticle = $this->article->find($id)->current()-
>toArray();
}
catch( Exception $e )
{
Zend_Registry::get('logger')->err($e->getMessage());
Zend_Registry::get('logger')->notice('User tried to do somthing
in articles that was not allowed');
$this->_helper->redirector('index','index');
}

The error I was getting is Fatal error: Call to a member function
toArray() on a non-object in. My catch code is not ever getting a
chance to gracefully handle the problem.

I read thourgh the documentation the result is supposed to be a rowset
object even if the query fails. But the toArray() causes the fatal
error.
