GeneXus 9.0: Web applications at their higher power Cecilia Abadie Project Manager GeneXus USA

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

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?

GeneXus 9.0 and WEB What’s new? Intelligent Client = AJAX + Client Side Validation Improvements in Presentation Layer: Design + Reusability Translation tools

AJAX Asynchronous JavaScript And XML Idea: Partial page updates with server info Asynchronous

Original web Traditional web Architecture Browser Server Web Server HTTP Request Web Server Interface HTML + JavaScript Logic and Data

AJAX AJAX Architecture Browser Server UI Event AJAX Engine Web Server HTTP Request AJAX Engine Web Server Interface Data Logic Data Logic UI Update Logic and Data

Client Side Validation (CSV) Browser Server UI Event CSV Logic Web Server Interface Avail. Data UI Update Logic and Data

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

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

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

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

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? www.gxajax.com (GXopen project)

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

Demo 3: Ajax manually Session timeout control

Talking about cost … (GXopen project)
