System Notifications

Use of System Notifications should target v2.2.0 as issues existed in v2.1.x.

Purpose
ACS AEM Commons System Notifications provide a means to deliver on-platform notifications to the Authors using the system.
This is a great way to communicate when system activities will occur, are occurring and have ended.

How to Use


Navigate to /miscadmin > acs-commons > Notifications
Create a new System Notification page


Complete the Notification form and click Save when complete


Visit any page on AEM Author to see the notification
Notification Fields

• Back Button: Takes user back to /miscadmin losing all unsaved changes
• Save Button: Saves changes to form
• Notification Preview: Displays preview of what notification will look like
• Enabled: Toggles if the notification is enabled or disabled; leave disabled and Save to get up to date preview.
• Style: Defines the color of the notification. Options: Green, Blue, Yellow, Red
• Title: The notification title
• Message: The notification message.
• Supports HTML (so be careful!)
• {{ onTime }} will act as a placeholder for a specified On-Time value (see 9)
• {{ offTime }} will act as a placeholder for a specified Off Time value (see 9)
• Unless prefixed with html:, all CRLF are transformed into <br/>
• Dismissible:
• If CHECKED, the notification can be dismissed for the duration of the user’s Session.
• Typically used for notifications informing something will happen or has happened.
• If UNCHECKED, the notification will display on every page load regardless if “Dismiss” is clicked.
• Typically used for notifications of occurring activities; especially ones where AEM Authors should NOT be using the site (ex. large content migrations, etc.)
• On-Time: Notification will display only AFTER this time and if Enabled (see 4)
• Can be referenced in the Message (see 7) with {{ onTime }}
• Off Time: Notification will display only BEFORE this time and if is Enabled (see 4)
• Can be referenced in the Message (see 7) with {{ offTime }}
