A form to remove events from the Activity Stream

Description

By default the Activity Stream is displayed on the front page of XWiki and sometimes there's a need to remove some entries from it (someone modifying a page with some rude language comment, creating/deleting a page that we don't want to show in the stream, etc).

This application allows removing some specific events from the Activity Stream.

Form to delete selected events

Notes

• The form is installed in Sandbox by default but it is an admin tool, once installed you can move page in a space of your choice
• The form shows only last 500 events by default
• After event deletion you must refresh the page to update the list displayed by the form (deleted event still show up in the list prior to refresh)
• Old Activity Stream events can be removed using the cleanup parameters that exists in the xwiki.cfg configuration file:
  #-# Number of days the events should be kept (0 or any negative value: infinite duration)
  #-# Note: if this value is greater than 0 a scheduler job will be created, this job will then be fired every week to
  #-# delete events older than the configured value.
  #-# Default: 0
  # xwiki.plugin.activitystream.daystokeepevents=0
