Variable empty in try block

Hi,

Im unsure if this is 100% the correct list, but I am using Perl to form
dynamic web pages (CGI afaik?) so I'll give it a shot.

I have a script which implements a try-catch block. Before entering the
try portion of this block, I am defining a variable and placing some
content into it, which is a hash table.

The problem seems to be that when I go to access this variable inside the
try block, and subsequently any catch blocks, or the otherwise block, the
variable seems to be empty.

Here is a snip of the code I am using:

        my $session = new App($query, $thisModule);

        try {
                $session->{AccessControl}->checkAccess();
                &$method($session);
        } catch App::AccessControlException with {
                my $e = shift;
                print "Content-type: text/plain\n\n";
                print "An access control exception has occurred.\n\n";
                print Dumper($e);
        } otherwise {
                my $e = shift;
                print "Content-type: text/plain\n\n";
                print "An error has occurred.";
                print Dumper($e);
        }

The first line creates a new instance of an object which contains some
runtime variables and other content based on the request being performed.

If I chuck the following line in immediately after the first line:

warn(Dumper($session));

I see the following in my webserver log file:

$VAR1 = bless( {
                 'thisModule' => 'module',
                 'Request' => {
                                'params' => [
                                              'b',
                                              'c'
                                            ],
                                'what' => 'a'
                              },
                 'cgiQuery' => bless( {
                                        '.parameters' => [],
                                        'use_tempfile' => 1,
                                        '.charset' => 'ISO-8859-1',
                                        '.fieldnames' => {},
                                        'escape' => 1
                                      }, 'CGI' )
               }, 'App' );

This is fine, its what I want to see.

But if I place this Dumper line inside the try block, I only see the
following:

$VAR1 = bless( {}, 'App' );

So it appears that the variable has no content inside the try block.

I dont see any complaints about the variable being undefined, so it
obviously exists, just not its content.

Can anyone think of a reason, or does anyone know the reason, why this
would be occurring?

Let me know if any further details are needed, or if you know of a better
list to post this question.

Thanks,
Tom
