Validation Triggers When-Validate-Item When-Validate-Record

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

Transactional Triggers Insert, Delete, Update Pre- Post- On-

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

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

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

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

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

Stacked Canvas Number of facets Each facet is a “canvas” Property to defines which canvas to render

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

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

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

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
