This works fine for returning scalars, but if I return an

Specifically the callback code is thus:
sub attributes : CallBack(attributes)
{
get_logger()->debug("ATTRIBUTES WAS CALLED");
my $df = XML::LibXML::NodeList->new();
for my $key (keys %{get_session_handler()->session()})
{
get_logger()->debug("key is $key");
my $e = XML::LibXML::Element->new('key');
$e->setAttribute('name',$key);
$e->appendText(get_session_handler()->session()->{$key});
$df->push($e);
}
use Data::Dumper;
get_logger()->debug("NODE LIST IS : ".Dumper($df));
return $df;
}
There used to be known issues with this, and I don't know if they were
fixed so your problem might require some backtracing and XS patching.
However I do note that the elements you return belong to no document,
which shouldn't happen. Maybe if you passed your function a node from
the document it's processing and used that document to create the
elements it would work better?
