Hi all,

I need to set maximum nesting level of pages in SiteTree. For example, content manager should be able to create Page page type in SiteTree root, and as a children of pages - but it should not be possible to create pages under another pages.
I created simple function, but it doesn't work.

	public function canAddChildren($member = null) {
		if ($this->CurrentLevel() == 1) {
			return true;
		} else {
			return false;
		}
	}

I used CurrentLevel() function posted by UncleCheese here:

CurrentLevel works fine when used in getCMSFields(), but in canAddChildren() it always returns 1.
