What to do
- Update test.def or test.py to add a complete expression to task t4
- Replace the suite
python: python python3 test.py ; python python3 client.py
text: ecflow_client --suspend=/test ; ecflow_client --replace=/test test.def - Observe the tasks in ecflow_ui
- See the triggers by selecting t4
- See the trigger relation by clicking on the arrow
- See the triggers in the tree, using the Show menu
- Note the icon indicating that the task has not run
- To check the triggers modify task t2 so that event b is not triggered; task t4 should run when t2 completes.
