Visiting JavaOne, one things becomes very clear: JSF is happening and will become the predominant web-technology for some years to come.
IntelliJ has for some years now been setting the standard for Java IDE's. Arguably IntelliJ is THE best Java IDE around and has always been the most innovative in its class in many, many very subtle ways that most people simply just overlook.
However, I think a lot of developers are going to consider other IDE's simply for their JSF support. I played around with some of the other IDE's and although none of them is anywhere near as good as IntelliJ, the JSF showcases are very compelling.
Forget Visual Fabriek (!!!), developers and companies want standards based solutions and not some proprietary framework. Without innovative JSF support like WYSIWYG drag'n drop, IntelliJ will very soon and very quickly lose marketshare to other IDE's.
Now GO get me some JSF support with the same innovative features that you guys are good at!!
