Has anyone tried using Ajax4jsf in the JBoss Portal environment ? I remember that 3 months back ajax4jsf was not supported for use with Portlets and at that time I went with DWR, which worked really well for me.
The support is added couple months ago. However, if you have something working fine, leave this alone. DWR and JSF have different programming paradigms. You will face a lot a pain transforming your mind.
