Event Management Dashboard - setting maintenance flag to "true" on alert that is part of alert group, doesn't remove the alert from alerts panel

Event Management Dashboard - setting maintenance flag to "true" on alert that is part of alert group, doesn't remove the alert from alerts panel

1. Install the Event Management plugin
2. Create 2 alerts with the same status (for example, both "critical").
3. Create alert group to include both alerts.
4. Go to dashboard, the red status of the group and 2 alerts in alert panel.
5. Open one of the alerts, set Maintenance status to "true".
6. Go back to the dashboard and see that alert is still presented with Maintenance flag "false".

This problem is currently under review. You can contact ServiceNow Technical Support or subscribe to this Known Error article by clicking the Subscribe button at the top right of this form to be notified when more information will become available.

A workaround is possible:

1. Create "dummy" business group with dummy condition (the result of the filter can be empty)
2. Create scheduled job that changes the status of the "dummy group" to operational state (if its operational set non operational and vice versa), it can run every few minutes.

The scheduled job will make sure that the dashboard is refreshed with the latest status.
