Async continuations: 2 simple script tasks

[nickerox]

Hi everybody,

Can anyone help me to understand what it is wrong in this code? Two simple script tasks (one of them "async=true") still works in sequential mode. The Activiti version is 5.14.  Many thx in advance

Sorry, I`ve not considered  scriptTask attribute <b>activiti:exclusive="false"</b>. It works.

Yes, the default is 'true', since for 'normal' users this makes most sense (chance for optimistic locking exception is high in case of jobs for the same process).
