[solved] Multiple instances of a model

Hi,

I would like to know if it was possible to have multiple instances of the same model in a controller.

For exemple, I'dlike to do something like that : 

$objects = array();

for($i = 1;$i < 10; $i++){
       $objects[] = new Objectmodel($i);
}

The only way I found to do that is to include the corresponding model file in the controller php file and remove the "extends My_Model".

Is there a better way to do that using a more CI compliant manner ?

Thank you for your help,

Fred
