      3. Create classic graph widget
      4. Select "Simple graph" and add item1
      5. Check "Dynamic item" and save widget and dashboard
      6. Set the refresh interval for widget "10 seconds"
      7. In another browser tab go to items and delete item1
      8. Go back to tab with Dashboard and wait until red unstyled error message appears in widget "No permissions to referred object or it does not exist!"
      9. Select "Host A" in dashboard controls

      Result: other item "item2" appears in the widget and an error
