Anyone with existing code based on Ext 3.x or earlier will sooner or later want to start taking advantage of the new capabilities offered by Ext 4. From MVC to charting to infinite grid scrolling, there are many reasons to upgrade, but where to begin? This session will provide practical strategies for migrating to Ext 4, including following the “Four R’s” of migration, dealing with common problems and pitfalls, debugging best practices, migrating custom components and much more. We’ll introduce the Ext 3 Compatibility layer and outline how it can minimize the time and effort required to convert your existing applications to Ext 4.
Presented by Brian Moeskau and Mats Bryntse.
