Struts - Solutions for creating Wizards

[Larry]

Hello everybody!

Let's discuss, what solutions do you prefer for creating Wizards. The main requirements are:
1. Chain of mappings with navigation buttons - Next, Previous.
2. All data in one transaction (rollback on Cancel or exception, commit on Finish).
3. Javascript Forms validation.

We were trying:
Struts-Workflow-Extension (Struts Workflow Extension)
Struts Flow (Struts Flow - Apache Struts - Struts Flow)
StrutsWizard 0.9 (Struts Wizard - a plug-in for Struts framework)
Easy Wizard (Superinterface - Easy Wizard)

The next challenge is to use one of solutions in Web 2.0 application (Wizard buttons do not refresh a page)

Does anybody used this solutions? And what a results?

Thanks

[Larry]

The problem is still important. Does anybody code wizards?
