The steps I use are as follows:
  1. Publish the proper WSDL (generate with Pod::WSDL) after having annotated your (dispatchable) classes with POD as described for classes in Pod::WSDL's documentation.
  2. Please check that the generated WSDL actually contains nice-looking descriptions of your classes (properly marked as complex types).
  3. Don't try to "construct" your complex types. Use normal hash-based perl objects. Return them (or arrays of them) directly.

I'll try to find the time to put up a working example soon.

Update:

Example of annotated class:

package Wholesale::Addon;

=begin WSDL
  _ATTR productid    $int      doc for attr.
  _ATTR name         $string   doc for attr.
  _ATTR description  $string   doc for attr.
  _ATTR price        $int      doc for attr.
  _ATTR windowIncr   $int      doc for attr.
  _ATTR computerIncr $int      doc for attr.
  _ATTR deferred     $boolean  doc for attr.
  _ATTR addonid      $int      doc for attr.
  _ATTR added        $dateTime doc for attr.
  _ATTR username     $string   doc for attr.
=end WSDL
=cut
sub new
{
  my $class = shift;
  my ($productid, $name, $description, $price, $windowIncr, 
      $computerIncr, $deferred, $addonid, $added, $username)  = @_;
  bless {
    productid    => $productid,
    name         => $name,
    description  => $description,
    price        => $price,
    windowIncr   => $windowIncr,
    computerIncr => $computerIncr,
    deferred     => $deferred,
    addonid      => $addonid,
    added        => $added,
    username     => $username
  }, $class;
}

#... methods omitted for brevity.

Example of method returning a list of complex values:

package Wholesale;
use Wholesale::Addon;

# other methods ommitted for brevity

=begin WSDL
  _DOC                       doc for method.
  _IN     username  $string  doc for param.
  _RETURN @Wholesale::Addon  doc for returnval.
=end WSDL
=cut
sub list_attached_addons
{
  # process arguments
  my $self = shift;
  my ($username) = @_;

  my @addons;
  
  # <snip>
  #   construct a list of Wholesale::Addon objects
  #   here using Wholesale::Addon->new(...) passing
  #   data retrieved from the database.
  # </snip>
  
  return @addons;

That all works fine for me.

Are you doing anything terribly more complicated than that?
