Conclusion
Business functionality is encapsulated on the
core business objects
Desktop class web applications based on Ajax

Oriented UI
Custom user interfaces can be specified through a
zero-learning-curve DSL
Code-hooks allows developers to reference the UI
components and write the ad-hoc customization

Coming Soon
DSL extension to support all DHTMLX components
(accordion, chart, spreadsheet.etc)
Mobile web application UI with DHTMLX Touch
Shiro Security integration
Improve the integration with the Isis Framework
