The management of alarms (escalation, and acknowledge) on the new MAP UI on version 31.0.0 does not work for user without ROLE_REST.
On the Alarms list UI it is possible to do it without the need for the user to have ROLE_REST.

How to reproduce:
Pre-conditions:

• Have a user, let’s say t1, with only role ROLE_USER. We can have another user, t2, with roles ROLE_USER and ROLE_REST if we want to do some other checks, but not needed to reproduce the error.

• Have at least one alarm which can be act on (escalated or un/acknowledged). If there is none, you can generate an event login as admin and using the Horizon GUI as explained here

• The node that has the alarm needs to have coordinates set on Assets with name Longitude and Latitude (to appear on the map view). Set them on the requisition, for instance.

Reproducing the problem:

• Login as the user without ROLE_REST (t1).

• Go to Maps->Geographical

• You should see an alarm on the bottom list of alarms.

• Select the alarm then select one “Alarm action” from the combo box on the top right of the alarm table.

• What happens: Nothing happens. Not only visually, the alarm action is not performed.

• What should happen: the alarm should be updated with the action (a new severity if escalated, for instance).

 Additional info:

• If we do the same but from the list of alarms we get from going to Status -> Alarms -> All alarms, we can see that this user, t1, is able to execute actions like escalate and acknowledge on that alarm.

• If we login with an user with ROLE_REST we can see that that user is also able to execute those alarm action from the table at Maps->Geographical (but we should need to give user ROLE_REST in order for them to use the UI).
