Hi,

Intalio|Ajax is one of the technology behind the form rendering. When a task is assigned to the user, the form linked to the task can be display using Intalio|Ajax.

Intalio|Portal describes the fact, that you can single sign on into the portal, 3rd party applications and intalio application in the same time.
The list of tasks of the user is displayed inside the portal using ajax.

ICEfaces is one of the possibilities to create a portlet within the portal. We do not make use of it right now, but this would be entirely possible.

Best Regards,

Nico
