Story->List() Limit Over 300 Errors

I am working on an XML feed (from the Bricolage.cc Site
Templates) that 
I have modified to include some other data. My goal is to be
able to 
generate XML feeds for certain categories, and even the
entire site.

I have got it working with limits <= 300. When I set the
limit in the 
xml_feed.mc template greater than 300 I get the following
error:

An error occurred while processing your request:
Can't call method "get_elements" on an undefined
value at 
/usr/local/bricolage/data/burn/comp/oc_1030/output_rss_feed.
mc line 49.
Please report this error to your administrator.

I think the upper limit for my number of stories is near the
5000 mark.

Can anyone shed some light on this?

Regards,

Wayne

I doubt it's related to the limit, but rather that a
particular
story after the 300th one is triggering this error in your
template.
What's at
/usr/local/bricolage/data/burn/comp/oc_1030/output_rss_feed.
mc
line 49 ?

Scott,

Line 49 begins with foreach:

  <item>
    <title><![CDATA[<% $title
%>]]></title>
    <link><% $url %></link>

    <%perl>
    foreach my $e ($page->get_elements) {
        if ($e->has_name('paragraph')) {
    if ($count <= 85){
           
$m->out('</p><i>'.$e->get_data.'</i>
<p>');
    }
    $count += {[split /s+/, $e->get_data]};
    }}
    </%perl>
<br/><br/><a href="<%

Thanks,

It means that $page is undef. What is $page?
I'd guess you have an off-by-one error or something.

%      my $page = $elem->get_container('page');
%      my $count = 0;

For each story I get the deck and then I have a page with
paragraphs, 
however using $elem->get_data('page') does not work.

It could be possible, though I don't know for sure that a
page could 
have only a deck and no page... is this where my problem
might be coming 
from? How do I deal?

Thanks for your help.

This is very likely the problem.
Print out $story->get_primary_uri and see which one it
is.

You should check all return values like that.
unless (defined $page) {
     $burner->throw_error("You need a page,
foo'!");
}

Is page a field or an element? If it's an element,
get_data() (and  
its new name, get_value()), won't work. You can use
get_elements() or  
get_container().
