1. ADF Task Flows For Beginners By Zeeshan Baig, Oracle ACE

2. A little about me..... I am currently working as Senior Developer at NMH in Chicago. ● 10+ years of experience in Oracle Development tools (Database, Forms, APEX, ADF, Fusion) ● Oracle ACE, OCP DBA certified in 8, 8i and 10g ● Technical blog on ADF and other fusion technologies at ● YouTube channel Disclaimer: The views expressed are my own and does not affiliates with my employer

3. Agenda ● What are Task Flows? ● Types of Task Flows? ● Other concepts used in Task flows ● Understand different components to build task flows ● Introduction of Task flows templates ● Some tips on building reusable task flows ● Demo ● Questions Thanks Google, and Oracle documentation for images used in this presentation. These images are unmodified and used for educational purpose only.

4. What are task flows their types and other concepts?

5. What are Task Flows? In simple words ● Visual representation of app process flow ● Each TF contains portion of app navigation ● They are similar to traditional flow charts ● Primary purpose is reuse

6. Types of Task flows Un Bounded Entry Points Bounded Entry Points Exit Points Exit Points

7. Types of Task Flows Key Differences Un-bounded (UTF) ● Public pages / No boundry ● No reuse ● No input parameters ● No return values ● No transaction Control ● No security ● e.g. Pages - Home, Help, Search, Navigations Bounded (BTF) ● Well defined boundry ● Reusable ● Can take input parameters ● Can return values ● Allows transaction control ● Security control ● e.g. Register, Checkout, other application processes

8. Bounded Task flows ● A typical application contains one unbounded task flow and many bounded task flows ● Build bounded task flows in its own application / workspace BTFs can ● Create with Pages or Page fragments ● Create as Train flows ● Call in a Dialog

9. Bounded Task flows Train Flows Video tutorial at html

10. Page vs Page Fragment Page Fragment ● Renders as content in another JSF page ● Must not contains the af:document, af:form, f:view, head, body and html because JSF page already has it ● has .jsff extension Page ● can contains many fragments ● extension .jsf or .jspx

11. Task flow Regions Static Regions ● Fixed visiblity ● Creates Task flow binding on page ● Tutorial http://www. baigzeeshan. com/2010/04/creating- pages-with-regions-in- oracle.html Dynamic Regions ● Visible based on custom logic ● Creates Multi-taskflow binding ● Tutorial http://www.baigzeeshan. com/2010/06/working-with-dynamic-regions- in-oracle.html Regions are created when you drag and drop a bounded task flow on a page

12. Task Flow Managed Bean Scopes 1. Application..... 2. Session.......... 3. PageFlow...... 4. View............... 5. Request......... 6. BackingBean. 7. Flash Scope.. Remains till application stops Persists till user session Also known as Task flow scope Lifespan till current page Lives for duration of request only UI Component based Remains Till Next encountered view (new in JSF 2.0)

14. OK I got it... now what components i need to build them?

15. Task Flow Components

16. Task flow Components View Activity ● Displays a JSF Page or Fragment ● Extension .jsf, .jspx and .jsff (fragments) ● Bookmarkable only in unbounded Task flows ● Can have one or more task flow regions ● Good practice to have page definition file attached

17. Task flow Components Method Call Activity ● Allows to call application logic in task flow ● Drag and drop methods from Data Control ● OR DnD from component palette then configure parameters to call managed bean methods ● Common usages are initialization, Clean-up, expcetion handler ● Can have return values in case of method returns some result ● if method is of 'void' type then outcome would be simple string

18. Task flow Components Router Activity ● Route to any activity based on EL expression ● Have default condition ● No Limits on conditions ● No limits on destinations ● Good practice is to start your task flows with Router for any future customizations.

19. Task flow Components Task flow call activity ● Calls another task flow from unbounded and bounded task flow ● Can take input parameters ● Can return output parameters ● Drag and Drop task flow from Application navigator to task flow ● Drag and Drop task flow to the page as link or button

20. Task flow Components Task Flow Return ● Used to ends or send controls back to caller in Bounded Task flows ● Does either Commit or Rollback (If Task flow is transactional) ● Set outcome to required control flow navigation-case. ● BTF can have many TF return activities

21. Task flow Components URL View Activity ● Used to Redirect application to addressable URL ● Can call BTFs ● Can call View activities on UTF ● Can call external sites e.g. http: // ● No Control returned to caller

22. Task flow Components Save point Restore ● Allow to restore application to previous state ● Supports Save for later functionality ● Only required where Restore needed

23. Task flow Components Parent Action Control flow case Wild-card ● Allows to trigger navigation of Parent view activity in ADF Region ● Identifies how control will paas from one activity to another ● Represents global navigation case

24. Building Task Flows

25. Building Task Flows

26. Task flow Templates ● You can create task flow templates for common activities in bounded task flows ● Common use case is error handler ● Best practice is to use template for all bounded task flows

27. How to Reuse Task flows in Different Application ● Create Deployment Profile ADF Library Jar ● Deploy as ADF library Jar ● Create Connection as File system in Resource Palette ● Drag and Drop from Resource Palette to your page and ADD libary path ● Complete Tutorial available at http: //www.baigzeeshan. com/2010/08/sharing-business- components-and-task.html

28. Tips to build Reusable Task Flows ● Build BTFs in seperate application then merge them into master app using ADF Lib Jar ● Use task flow with page fragments ● Use Input parameters ● Use Router activity as default ● Set conditional behaviour of UI components based on Input parameters e.g. read-only, show/hide ● Use dynamic regions

29. Demo Example ● Search Employees - Provides Search facility Secured, called as normal on Home page and as List of values on upload photo task flow ● View / Edit Employees Secured, Allows 'Managers' to edit and 'endusers' to view employee detail. Displayed as ADF region and deployed as ADF library jar ● Upload Photo - Task flow to upload employee photo Secured, Called as Dialog and later calling search flow in a model dialog ● Public Runs a flash movie on home page for all unauthenticated users for authenticated users displays graphs based on user type
