I have already created a ticket with the same question but I cannot find it. I hope that I am not creating a duplicate.
I have defined a very simple workflow, attached below, that contains a subprocess. The subprocess contains a user task, a timer boundary configured to fire every minute for five times and a mail task.
The timer boundary does not seem to work and I was expecting. All the 5 emails are sent in the same time: after the first minute.
I can see that a job is added that seems to have the right configuration. The job is removed after the first minute.
Please find attached the workflow definition.
