First of all, there are different tasks to be performed by different actors and furthermore, the tasks are starting at different times. So they are not 'sequential' as such - there is simply a constraint on them finishing in a particular order. If I stick them all on a single task node, or put a lot of code behind to organise this ordering, then it makes it much more difficult to change the process through changing the graph. It would also hide this part of the process. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130308#...
