[jboss-user] [jBPM] - Parallel gateways really parallel?

Tobias Wittur [http://community.jboss.org/people/tob1as] created the discussion "Parallel gateways really parallel?" To view the discussion, visit: http://community.jboss.org/message/628338#628338 -------------------------------------------------------------- Hi, I was trying to throw and catch a message while also running a count down timer, that terminates the process in case a message is not received within a certain time. I therefore used a parallel gateway. I ran into some issues and wonder now, are the different branches running in parallel or randomly sequential? In this process, my service task on the top throws a message, which the intermediate message catch event receives and successfully executes.The service task asks the user per command line, if a message should be thrown. http://community.jboss.org/servlet/JiveServlet/showImage/2-628338-17049/C... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-628338-170... I then tried to introduce the timer as a thrid branch. However, the timer is never started. It never "runs into check if message received within time frame". http://community.jboss.org/servlet/JiveServlet/showImage/2-628338-17050/C... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-628338-170... I then remodelled the process. Here, suddenly the intermediate catch event is never executed. http://community.jboss.org/servlet/JiveServlet/showImage/2-628338-17048/C... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-628338-170... Are those parallel gateways executed sequentially or do they run in separate threads and are executed in parallel? I know usually I would use an intermediate catch. However, I have to present my process to my boss next week and I have to show, how easily I can introduce change in a modeler to a process and execute it. So subprocesses and event based splits are not an option for this model.
