Hi, I've a script exteding the main page class

class CustomExtention extends DataExtension { }
+
Object::add_extension('Page', 'CustomExtention ');

All good, however, on a site where there is another module already extending the 'Page' class, this 2nd extension doesn't seem to be picked up

Is it only possible to have one dataextension on any one class? If that's true, is there any kind of work around?

cool, seems to work now using to add some content into the header...

public function contentcontrollerInit($controller) { }
