Use e4 as an AUT.
- Go to Window/Preferences/General and make sure that Open mode is set to Double click.
- Capture a preference context (you may find OPEN_ON_SINGLE_CLICK=false preference in org.eclipse.ui.workbench preferences).
- Go to Window/Preferences/General and switch Open mode from Double click to Single click.
- Apply preference context. Go and check. It is still Single click although it should be either restored to default (because "clear preferences" option is set in a context) or set to false (because we have false value for this preference in a context). None if this has happened.
Should I record a separate ECL context which press "Apply" button for this preference?
How should I discover if preference needs this or not in future?
