rthis was kind of what I had in mind as well. The problem is going to be how to check/remember if both events have occured. And what if you have more than 2... use process-variables or check the state of a node/task? The latter would be better I think. btw... you can post in xml if you surround that part by [c o d e] [/c o d e] tags (without spaces) you can also include a minimal unit test then. I'll see what this approach does for me. The other soultion is to use a guarded transitions which e.g. check the processvariables mentioned above and write some code that signals the other nodes. Whether it continues depends on the variables then. btw, I send you a message on greg(a)gnome_hu. Is that correct?
