Which three options are available in the ADF Controller that are not available in the generic JSF 2.0 controller layer? (Choose three.)
A. pageflow scope: a memory scope for managed beans that is available for several pages (longer than a request scope and shorter than a session scope)
B. ability to break the page flow of an application into multiple files
C. subflows that can be included as regions inside a page
D. method calls as part of the definition of a page flow
E. defining managed beans that contain references to components on a page
Correct Answer: ACE
Explanation/Reference:
A: ADF Memory scopes
There are 6 types of memory scopes
3 from standard JSF application
1) Application Scope 2) Session scope 3) Request scope
In addition to above ADF Faces provides the following
4) PageFlowScope 5) BackingBeanscope 6) ViewScope
C: There is no such thing as subflows in JSF, but they do exist in ADF.
E: Backing bean scope:
Special case of request scope
Associated with a specific manage bean instance
Used with declarative components, regions and page fragments that use a managed bean to hold view state information
Allows multiple instances of the components to co-exists on a single page
Use this scope if it is possible that your task flow appears in two ADF regions on the same JSF page and you want to isolate each instance of ADF region
