Updates Framework for RPG-Centric Web Development on IBM i CHICAGO, IL. CNX announced today the first post-Beta release for version 3.0 of the Valence Web Application Framework for IBM i. Valence 3.0 includes numerous browser component enhancements and adds mobile device support to the package, providing state-of-the-art tools for IBM i programmers to create true Web 2.0-style applications for virtually any device with a browser. “This latest version of Valence is more than just an incremental release,” said Richard Milone, CNX Chief Technical Officer. “For starters, the portal has undergone a beautiful redesign with some great new features to make it easier to use than ever. And with native support for mobile devices now included, this release will be of particular interest to developers who want to address the rapidly growing community of smartphone and tablet users.” Designed explicitly for RPG programmers, Valence 3.0 includes Sencha Ext JS components for the front-end browser that communicate directly with RPG programs on the back-end IBM i server.
As with prior releases, the Valence 3.0 framework includes an intuitive web portal for controlling IBM i library lists and security for all programs, as well as an intuitive navigation tree from which users can launch the browser applications to which they are authorized. When mobile devices such as iPads are being used, the Valence Portal now automatically switches the interface to a native Touch-friendly format. Valence 3.0, the seventh major release of the Valence Framework since it was launched in May 2008, includes the following new features and enhancements:
- Mobile device support – with Sencha Touch included, Valence now supports a wide range of mobile devices, including iPads, iPhones, and devices running on the Android OS.
- Updated Ext JS library – The latest release of Valence's front-end framework from Sencha (Ext JS 4.0.1) features faster component rendering, updated grids, new APIs and classes, advanced charting and graphing options, and much more.
- Valence Portal improvements – The Portal will now recognize when it's being launched on a mobile device and automatically switch to a new touch-friendly format; On the desktop, users can configure the Portal to use a drop-down menu in lieu of the standard navigation tree to launch apps; Users can also now switch between environments without having to log out. Administrative apps have been reformatted to make it easier to see which users have authority to which applications; New configuration settings have been added to make it easier to add new apps to groups and navigation trees
- Updated examples and applications – Many of the example programs have been updated to showcase use of new Ext JS 4 features, and new examples have been added to demonstrate Touch application development; Administration programs have been rewritten to demonstrate a more modern object-oriented front-end using Ext JS 4.
- New back-end RPG functions and improvements – Developers can now cache frequently accessed lists for faster rendering in combo boxes between applications; SQL-to-JSON functions have been further optimized to improve response time.
