Hi all,

I have some parent and grandparent checking to do.

Parent checking is as so (in Page model):

function getParent(){
		return ($this->Parent())? $this->Parent()->Title : false;

This works fine.

Grandparent checking is as so (in page model)

function getGrandparent(){
			return $this->Parent()->Parent()->Title;
			return false;

Grandparent checking fails with the following error:

"Call to a member function Children() on a non-object "

Now, the class tree should be:
BookHolder -> BookList -> BookPage

I've set up BookList to have BookHolder as a parent, so a call from a bookpage, which sits in a booklist (which belongs to a bookholder) should return the title of the BookHolder page?

Or am I missing something?

Happy to clarify more if required,
