Getting into the code

• ADF BC doesn’t “generate code”• “default” XML definition

• Allows you to expose more and more of the implementation code

Getting into the code

• Exposing code in the Entity Object

Getting into the code

• Exposing code in the View Object

Getting into the code

• Exposing code in the Application Module

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

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)

Adding “trigger” code

Searching and Querying

• Parameterize search form• ADF Search Form• ADF provides option to “ExecuteWithParams”

• Execute Query

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

Auto Submit

Conditional UI Processing

• JSF Expression Language (EL)• Backing/Managed Beans

Stacked Canvas

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

canvas to render

Stacked Canvas

Conditional Page Flow

• Button action returns a string• When-Button-Pressed

• Define page flow based on runtime criteria

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
