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.
