9. Getting into the code • ADF BC doesn’t “generate code” • “default” XML definition • Allows you to expose more and more of the implementation code

10. Getting into the code • Exposing code in the Entity Object

11. Getting into the code • Exposing code in the View Object

12. Getting into the code • Exposing code in the Application Module

13. Common “Forms Trigger” points • Validation • When-Validate-Item, When-Validate-Record • Query • Pre-Query, Post-Query • Transaction • Pre-Commit, On-Commit, Post-Commit • Pre-Insert, On-Insert, Post-Insert • Pre-Delete, On-Delete, Post-Delete

14. Validation Triggers • When-Validate-Item • When-Validate-Record

15. Query Triggers • Post-Query • Non-base table population • Running totals • Pre-Query • Modify query

16. Transactional Triggers • Insert, Delete, Update • Pre- • Post- • On-

17. The Best of the Rest • When-Create-Record • When-Remove-Record • When-Button-Pressed (UI processing – later)

18. D E M O N S T R A T I O N Adding “trigger” code

19. Searching and Querying • Parameterize search form • ADF Search Form • ADF provides option to “ExecuteWithParams” • Execute Query

20. D E M O N S T R A T I O N Adding search code

21. D E M O N S T R A T I O N Calling a stored procedure

22. Next Level – UI Processing • Auto Submit • Conditional UI processing • Expression Language validation • Backing/Managed Beans • “Stacked canvases” • Conditional page flow

23. Auto Submit • HTML UI validates only on POST • ADF Faces provides Partial Page Rendering • AutoSubmit submits page when field changed • PartialTrigger defines fields that re-act to changes

24. D E M O N S T R A T I O N Auto Submit

25. Conditional UI Processing • JSF Expression Language (EL) • Backing/Managed Beans

26. Stacked Canvas • <af:switcher> • Number of facets • Each facet is a “canvas” • Property to defines which canvas to render

27. D E M O N S T R A T I O N Stacked Canvas

28. Conditional Page Flow • Button action returns a string • When-Button-Pressed • Define page flow based on runtime criteria

29. D E M O N S T R A T I O N Conditional Page Flow

30. Summary • ADF provides Forms developers with • All your favorite triggers • Many of the common Forms concepts • Stacked canvases • Defining search criteria • Conditional page flow • And a lot more besides! • JDeveloper and ADF continue to provide more and more productivity features for Forms developers
