Hey guys, whenever I try to save a product in the CMS using the latest SS and eCommerce (burnbright) I get the following error

ERROR [User Error]: Uncaught Exception: Object->__call(): the method 'setbyidlist' does not exist on 'DataObjectSet'

Any ideas?

Okay guys if you find this thread and have the same problem, here is what it was for me

In Page.php I had added a method called ProductGroups() which would return all the product groups so that every page would have access to it for a sidebar I wanted to have

class Page extends SiteTree {

public static $db = array(
);

public static $has_one = array(
);

public function ProductGroups() {
return DataObject::get("ProductGroup","",null,null,null);
}

}

Unfortunately for me, the official method for getting the ProductGroups in the CMS admin panel has the same name, but returns a different variable type (ComponentSet rather than DataObjectSet) and that is why the problem occurred!

Hope this helps somebody
