Glad to see this is of interest. I'm currently travelling and will provide more details when I return. A couple of clarifications. I have a prototype message bean to handle inbound iCal attachments...I was wondering about modelling a process to manage task assignment states (e.g. assigned, declined, accepted etc). Something I see jBPM deliberately avoids. Also, regarding mobile notifications I was referring to calendar sync to blackberries, etc (message push) and the like. cheers Adrian View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135782#...
