Modifying properties

The Controller SPI allows you to modify properties resources.

To modify properties of a resource, proceed by the following steps:

1. Obtain the appropriate controller for the model of which you want to modify a resource.
2. Obtain a modifiable instance of the resource from that controller.
3. Invoke the appropriate methods of the modifiable instance to perform the modifications.
4. Persist the modifications by using the commit() method of the controller.
