Below an answer i got by mail from francois, i don't see it as a reply, so incase anyone is looking for the explanation later, tnx francois
Hi, Due to late static binding not being implemented yet in PHP, what you ask is impossible... Check this link for more info: http://de2.php.net/manual/de/function.get-class.php#77698 But, there is a workaround. Say you wrote a `myFinder` class with custom methods that you want to use in several models: class myFinder extends DbFinder { // custom methods ... } If you call: $finder = myFinder::from('Article'); then `$finder` is an instance of `DbFinder` - this is the Late Static Binding problem. But if you define a custom `ArticleFinder` class extending `myFinder`, as follows: class ArticleFinder extends myFinder { protected $class = 'Article'; } Then calling: $finder = DbFinder::from('Article'); will return an `ArticleFinder` instance, which inherits from `myFinder`. And that means you can use your custom finder methods on several models.
