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

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

• When-Button-Pressed
• Define page flow based on runtime criteria
