I think Portlet support is critical, especially since it's in there and working now :-) I haven't looked at the portlet implementation, but what I remember from the discussions was to allow you to map different action configurations for different lifecycle calls of one portlet, so you might even have different action classes doing the minimize vs. render. The dispatcher in this case is actually implemented as a Portlet which is plugged into the portlet container and is told which actions to use for different phases. Of course, as I said, I haven't used it, so I could be wrong :-) --------------------------------------------------------------------- Posted via Jive Forums http://forums.opensymphony.com/thread.jspa?threadID=29317&messageID=57317#57317 --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
