bgribaudo, in my code and all the examples i have seen it is required to have a reference to your page type from the resource object. Are you sure you shouldn't have something like

class QualityPDF extends PDFResource
   static $has_one = array (
      'Page' => 'QualityPDFPage '

and then you could setParentClass('QualityPDFPage')

Good Luck, I'm no expert.

Yeah, the parent class has to be the one that's in your has_one relationship. Put it this way.. setParentClass() tells the table which ID field it will update. so setParentClass('Page') means it will try to update PageID on the object. setParentClass('QualityPDFPage') will try to update the field QualityPDFPageID.

@David -- Thanks for these fixes. I've checked them in.

Not sure if this has been posted but here is the link to the module on the unsuported modules page

There is a "small bug" behind the links on page navigation for lists. The parameters of First, Next, Previous an Last are twice in parameter string.

Hey! Look at that! It got posted. Finally. Still waiting for the ImageGallery to get some love.

@hu - Thanks for the heads up. I'll look at that.

Uncle Cheese,

I think I'm missing something. I'm setting setParentClass('Page') on the FileDataObjectManager instance, yet PDFResource's PageID column stays set at 0. Any clues?

Can you show me QualityChildPage?

Sure thing.

class QualityChildPage extends Page {
	static $db = array('Category' => "Enum('Links, Workplace, Family, Stories, Extras','Links')");
	static $default_parent = 'QualityHomePage';
	static $can_be_root = false;
	static $allowed_children = array();
	static $icon = "themes/memberscf/images/pageicons/cqarticle";

	function getCMSFields() {
		$fields = parent::getCMSFields();

		$fields->addFieldToTab('Root.Content.Metadata', new DropdownField('Category', 'Category', singleton('QualityChildPage')->dbObject('Category')->enumValues()));
		return $fields;
	function Quality() {
		return $this->Parent()->Quality;

class QualityChildPage_Controller extends Page_Controller {
	protected $sidebar = 'QualitySideBar';

    public function CategoryLinks($category) {
        return QualityHelper::CategoryLinks($category, $this->Parent());

class QualityHelper {
	public static function CategoryLinks($category, $quality) {
        $results = new DataObjectSet();
        foreach($quality->Children() as $child) {
            if ($child->Category != $category) continue;
        return $results;
