Activiti Release Notes

Release Notes - Activiti - Version 5.4

Compatibility note

After releasing 5.3, we discovered that execution listeners and task listeners and expressions were still in non-public api. Those classes were in subpackages of org.activiti.engine.impl..., which has impl in it). org.activiti.engine.impl.pvm.delegate.ExecutionListener, org.activiti.engine.impl.pvm.delegate.TaskListener and org.activiti.engine.impl.pvm.el.Expression have been deprecated. From now on, you should use org.activiti.engine.delegate.ExecutionListener, org.activiti.engine.delegate.TaskListener and org.activiti.engine.delegate.Expression. In the new publicly available API, access to ExecutionListenerExecution.getEventSource() has been removed. Apart from the deprecation compiler warning, the existing code should run fine. But consider switching to the new public API interfaces (without .impl. in the package name).

Release Notes - Activiti - Version 5.1

Warning

The automatic upgrade does not have enough coverage to have full confidence. For more info, see the user guide, section Database upgrade.

Changes

• In attribute <serviceTask delegateExpression="..."> previously always performed a leave after calling the delegate that was obtained by evaluating the expression. Which means that it's always an automatic activity. Now the leave is only performed only when the delegate object implements JavaDelegate. In case the delegate object implements ActivityBehavior the leave will not be called. In that case, the ActivityBehavior is responsible for calling leave if it wants to be an automatic activity.
