What to do
- Edit the suite definition file to add the trigger.
- Replace the suite.
- Observe the tasks in ecflowview.
- See the triggers by selecting t1 or t2 and clicking on the
icon. - See the trigger relation by clicking on the arrow.
- See the triggers in the tree, using the Show drop down menu.
- Search any reference to t1 by using the
