Hi Alan,
Thank you for the explanation. I think Taverna could be even better with
parallel execution of beanshell so maybe it's a good idea to open a Jira
issue.
For my case, I don't need my script to be a beanshell script. I just want
my (parallel) nested workflow to wait until a date is rich before
continuing the execution. Do you have other solutions in mind ? A
windows/linux shell script ?
