Hi,

I am using activiti in my spring application and i would like to use timer start event for every minute. I designed the bpmn file and deployed. but it isn't working to trigger the business logic.

Please check and help me out of this.

<timeDuration>P1M</timeDuration> this will run once every month. Try <timeDuration>PT1M</timeDuration> instead.

Check out ISO 8601 - Wikipedia for more info about durations.

PT1M means for for every minute right? But it is executed first time only. I would like to execute for every minute. Please tell me if you know about this.

What version of activiti are you using? As mentioned in Activiti User Guide timers are only fired when the job or async executor is enabled. Do you have them enabled?
