Using ADF Task Flow Components (continued)

to-activity-id: Specifies the activity to navigate to as a result of a control flow case

train-stop: Specifies that the activity is one of a sequence of defined steps

transaction: Specifies whether a called ADF bounded task flow should join an existing transaction, create a new one, or create a new one only if there is no existing transaction

url-view: Used to redirect the root view port (for example, a browser page) to any URL addressable resource

view: Used to display a JSF page or page fragment (page fragments are explained in the lesson titled “Ensuring Reusability”)

2. Components:


Method Call: Invokes a Java method from within a task flow

Router: Performs conditional routing depending on the outcome of an expression

Save Point Restore: Enables restoration of a previous persistent save point in an application that supports save for later functionality (This functionality is described in the lesson titled “Implementing Transactional Capabilities.”)

Task Flow Call: Invokes another task flow

URL View: Redirects the root view port, such as a browser page, to any URL-addressable resource

View: Displays a page or page fragment (Page fragments are explained in the lesson titled “Ensuring Reusability.”)

Control Flow:

Control flow case: Identifies how control passes from one activity to another

Wildcard control flow rule: Global navigation rule

3. Diagram Annotations:

Note: Adds a note to the task flow diagram

Note Attachment: Attaches an exiting note to an activity or control flow case in the diagram
