Description
This application adds a new "notifications" menu in the top bar, represented by a bell:
, you can find in this menu the notifications about some events happening on the wiki (a page has been modified, a new blog post has been posted, etc...).
The number of notifications is displayed on the top menu, just above the bell:
, if you have more than 20 unread notifications, you will not see the real count but this instead:
When you open the menu, the content of the notifications is loaded (before 9.11RC1, it was instantaneous):
Then you can see the list of notifications:
If you click on the little button with the "check" icon, you mark the notification as "read". In the future, you will be able to select either you want to see only unread notifications or all of them.
When the notification is read, the button disappear and the background color changes:
The "Clear All" link will remove all notifications that were sent till now.
When no notification is available, you will see the following:
Group of notifications with details
Similar notifications are grouped together in order to avoid a batch of identical content. Only one notification is displayed, and it is possible to see the details of all activities in the "Details" section (if any). Example:
Get a notification RSS feed
, you can get a RSS feed of the notifications occurring in your wiki. This feed can be accessed either through a link in your notification tray (or at the bottom of the notifications macro).
Notifications Macro
Settings
On the notifications menu, you also have a link to go to the "settings" of the notifications.
By default, users don't get any notification. You need to select which "types" of notifications you want to receive. When a page is created? When a blog post is published?
You can enable or disable all notification types that belong to a particular application by clicking on the bells associated to this application. If some types are enabled and other are disabled inside an application, the switch looks like the next screenshot, meaning that the application's notifications are partially enabled:
Note that when you turn on notifications you see all past notifications till now. If you wish to only see future notifications you can click on "Clear All".
Filters
There is a "Filter" box on the bottom of the settings we have yet described.
These filters allow you to restrict on witch locations you want to receive notifications, for each event type.
To add a new filter, click on the "add a filter" button :
You will see a picker that will let you chose either a page or a wiki and a selector to choose if the filter should be inclusive or exclusive. When you select a page, the filter will also be applied on its nested pages, unless it is a terminal page.
, you can also define exclusive filters. You can then exclude some pages from your notifications.
Note that exclusive filters take precedence over inclusive filters.
, default notifications filters can be added to a wiki. When a default notification filter is registered, it appears as enabled in the notification center of every user.
Each user can then access the "Advanced filtering options" panel in order to enable or disable those notification filters.
, all filters are displayed in the same table:
Hidden (technical) pages
, filters that concern hidden pages are not shown in the table, unless you have enabled the option to see hidden pages. That is why you can end up in a situation where filters exist but are not listed there.
Filter your own events
By default, one don't receive notification about her own activity. , you have the ability to disable this filter in the "Advanced filtering options" section of your own notification settings. It's a per user setting, not a global one.
Filter events that you have marked as read
, you can hide the notifications that you have marked as "read", so they won't appear anymore in the notifications menu nor in the emails.
Filter minor events
, minor events are not displayed on the notifications. But you can disable this filter.
Watched Entities
You can also decide to watch some entities. Either a location (a page, a page with its children or a wiki) or a user (planned for 9.9).
Enabling/Disabling the feature
, the feature is enabled. But you can disable it if you want to use the old Watchlist Application instead.
You need to modify the following line of the xwiki.properties file:
#-# Indicate if the "watched entities" feature is enabled on the platform.
#-# This feature mimics what the "Watchlist Application" does so it may not be a good idea to have both on the platform.
#-#
#-# The default is :
# notifications.watchedEntities.enabled = true
Using it
To watch a location, all you need is to go to that place, and then click on the "alert" menu (represented by a bell).
Here you can decide to watch either this page, this page and its children, or the entire wiki.
On the notifications settings (in your user profile), you will see the watched entities in the filters box:
Since 9.9, you won't be able to click on the buttons if you don't have enabled some event type first:
Auto Watch
By default, a page where you have made a major modification is automatically added to the list of pages you watch. It means you will be notified about changes on your work. You can change this behavior in the settings:
Follow a user
If you go to the profile of an user, using the User Index for example, you can see decide to watching a user. It means you will receive all notifications about events triggered by this user.
In your user profile, if you go to the "network" tab, you can see the list of users you are watching and the events that have performed:
Coexistence with the Watchlist Application
If the Watchlist Application is installed, you will have two rows of buttons instead of one. The first row concerns the Watchlist, and the second, the notifications.
You will also receive 2 emails: one from the Watchlist, and one from the Notifications Application. That is why we recommend to uninstall the Watchlist when you use the "Watched Entities" feature.
Emails
You can also select some types of notifications that you will receive by email. You can have different choices enabled by email and in the menu. Then, on the very bottom of the page, you can select the interval between 2 emails. For example, if you choose "Daily" (default), you will receive one email every day with the recap of the events that have happened during the day. Of course, if there were no activity in this period of time, no email is sent.
, live notifications emails can be sent to a user. The wiki administrator can also define a "grace time" for live email notifications ; when an event that triggers a notification is sent, the platform will wait for the duration of this grace time before sending a notification email. If during this interval, a new event of the same kind is sent, the two events will be grouped in the same email. You can get more informations on how to configure this feature here.
Of course, it works only if the user has properly filled her e-mail address.
You can edit the frequency of your email notifications by using the selector just at the bottom of the notification preferences pane in your profile page :
, the notifications are sorted by pages and dates, and a table of content summarizes all notifications contained in the email:
, a breadcrumb is displayed on top of each notification that concern a page:
Details of the changes
, the changes are displayed in the email content:
Select the level of details about the changes
In the user profile of the user, you can select the level of details that you receive on the email, about the changes that have happened to the wiki:
The current choices are:
- Standard
- Nothing
Macros for settings
the application proposes 3 wiki macros to handle the user's settings that could be called in many pages. These macros are:
| Macro Name | Screenshot |
|---|---|
| {{notificationsEmailPreferences/}} |  |
| {{notificationsApplicationsPreferences/}} |  |
| {{notificationsFiltersPreferences/}} |  |

#-# Indicate the grace time used when sending live email notifications.

Threads allocated to the user notification system
all the requests which are searching for notifications for the current user go trough a thread pool with low priority in order to limit the impact of this feature on the rest of the XWiki instance. By default only 2 threads are allocated but it's possible to modify this (or disable the system completly) in xwiki.properties.
#-# XWiki instance.
#-# This properties controls the size of this pool. Any number lower than 1 disable the thread pool system.
#-#
#-# The default is :
# notifications.rest.poolSize=2
