Hi all,I want to design a basic process that sends sms to user(Indeed it is a part of a big process). If the service task that sends sms throws exception i want to try 3 times with 1 minute interval. If the sms couldn't sent i want to end process(or go to next step). I designed a process like in the attachment. But after trying to send sms twice, the process suspended and waits in dummySmsST service task. 1) In Start Event, i add an alfresco script that sets retryCount variable to zero. execution.setVariable("retryCount",0);2) In dummySmsST i call the service that sends sms. 3) There is a boundaryerror attached to dummySmsST.4) When exception occurs process goes to Receive Task. In Receive Task the retry count is increased by 1. execution.setVariable("retryCount",retryCount+1);5) In boundaryTimer attached to Receive Task, i set the time duration to PT1M.6) In Gateway's left flow i added a condition that checks for retryCount. ${retryCount<3}7) In Gateway's right flow(default flow) i do nothing. It goes to endevent.Is there any design problem or script problem. I need your suggestions.Here is the log :
