I'm using design 5.5.0 and see a small issue. If I have currently selected a service task which has a 'result variable' and then create a new service task the 'result variable' for new task is set to the value of previously selected task.
Minor isssue not causing any problems - just thought you may want to know. I don't know if I can log issues in jira.
This happens also if I select an existing service task with a 'result variable' and then select another existing service task which has no 'result variable', ie. the result variable of the first appears in second task's properties.
It's a little more intrusive than I thought and indicated in first posting.
