2. Web applications Origin Evolution Documents with Hyperlinks E-commerce
On-line applications
Intranet/Extranet
ASP – Application service provider
Portals

3. Web applications Strengths Weaknesses
Esthetically appealing
Installation free (browser + TCP/IP)
Multi-platform
Great user adoption
Weaknesses
Rigid Applications (GET-POST)
Bad interaction
Document Oriented
Lack of richness and responsiveness
Are we pushing the limits of www?

AJAX + Client Side Validation
Improvements in Presentation Layer: Design + Reusability

10. Client Side Validation (CSV)
Goal: stay in the client
Use the information already available in the client:
Loaded when the page was first loaded
Loaded with a requirement to the AJAX engine

11. CSV + AJAX = Intelligent Client
Not always has all the information it needs
AJAX is the solution to bring the data as it is needed

12. CSV + AJAX = Intelligent Client
GeneXus 9.0 implements CSV + AJAX for WEB Applications
Allows
Formula Triggering
Rule Validation
Extended table loading without need of pressing a button and submit page
Result?
Similar behavior to GeneXus Windows

13. Demo 1 – What we had Simple GX 8.0 Invoice: “Bad Habits”
“Forced trips” to the server for:
Inferences
Loading FK secondary attributes
Rules triggering
Formulas calculations
“Bad Habits”
Little interactivity when filling forms
Late error detection
Extra screens

14. Demo 2 – Intelligent Client
GX 9.0 Invoice
Automated things:
Mode inference
Rule triggering
Formula calculations
New features:
Input Type
Suggest
Dynamic dependent combo boxes
What’s the cost?
(GXopen project)

15. Cost?
Inferences, rules, formulas?
Suggest, Input Type, Combo Boxes?

16. Demo 3: Ajax manually
Session timeout control

17. Talking about cost …
