ICE78 verifies that the AdvtUISequence table either does not exist or is empty. This is required because no user interface is allowed during advertising.
ICE78 posts an error if the AdvtUISequence table exists and is not empty.
ICE78 reports the following error for the example:
Action 'Action1' found in AdvtUISequence table. No UI is allowed during advertising. Therefore AdvtUISequence table must be empty or not present.
To fix the error, either remove "Action1" from the table, or remove the table.
