in thread WWW::Mechanize follow_link() crashes if no link is found

Hi,

First thanks for the reply.

But, Pardon me for my ignorance. I didn't get your point.

Is there any way to make my program move on with the next step rather than crashing at follow_link line?

Thanks

    If all else fails, you could trap the exception, i.e. wrap the call within eval { ... } — Something like this 

    my $foo;          # undefined
eval {
    $foo->url();  # would 'Can't call method "url" on an undefined val
+ue ...'
};
if ($@) {
    # ... handle the exception
    print "error: ...: $@\n";
}

    Well, one way would be to always pass a valid link to be followed. The other would be, as is specified in the WWW::Mechanize docs, to set autocheck to 0. Although, this would silence all requests unless they're errors.
