CHAPTER 11The ADF Controller and Task Flows

We herd sheep, we drive cattle, we lead people.Lead me, follow me, or get out of my way.

—George S. Patton (1885–1945)

The ADF Controller (ADFc) is one of the most important new features of the ADF Framework introduced with 11g and a key part of any Fusion technology based application. Unlike other major parts of the framework, such as ADF BC, the ADF Controller is a totally new feature, although it will have some familiar concepts and features for developers that have built applications in Apache Struts or JavaServer Faces in the past. The key artifact that the controller introduces into the framework is a task flow, which is the metadata that the developer creates to configure the controller’s operation. ...
