New subject: [xwiki-users] Fw : Re: How can I get event object through a form

19 Jan 2016

...

 Did you try using searchEvents and building an HQL that
 retrieves the Event object with the given IDs? Then, once
 you get the Event objects, you can use
 deleteActivityEvent on each of them. 
That is what I was affraid of ... hql query. I though there was a simplier way like
xcontext stuff or convert id in event object ;-)
Thxs I will give a try  (must found id field and table)

...

 I try to make an Admin form to delete some event from
 activity stream.

 I manage:

 - to list events in a checkbox list

 - to delete an event

 #foreach ($MonEvent in
 $xwiki.activitystream.getEventsForUser($MyUserr, false, 300,
 0))

       #if
 ($MonEvent.getPage()=='MySpace.MyPage')

         * event deletion

 $xwiki.activitystream.deleteActivityEvent($MonEvent)

       #end

 #end

 - but I didn't manage to pass an event id/object with
 form to my deleteActivityEvent method :-(

 It doesn't work because when I get my event through
 $request.getParameterValues('IdEntry'), event ID is
 transformed in text and is not event object anymore.

 I use velocity with xwiki 7.0.1 and my page contains this
 code:

 **********************************

 {{velocity}}

 {{html}}

 ## My form to select events to delete

 <form method="get"
 id="DelActivityStream" onsubmit="return
 confirm('Are you sure?')">

 <div class="container">

   #foreach ($MonEvent in
 $xwiki.activitystream.getEvents(false, 200, 0 ))

     ##1. AAA $MonEvent - $MonEvent.getPage()

     #set($MycheckBox="<input
 type='checkbox' name='IdEntry'
 value='")

     #set($MycheckBox=$MycheckBox +
 "$MonEvent")

     #set($MycheckBox=$MycheckBox + "'/>"
 + "$MonEvent.getPage() - $MonEvent.getDisplayDate() -
 $MonEvent.getType() - $MonEvent.getPriority() -
 $MonEvent.getUser() - $MonEvent.getEventId() -
 $MonEvent.getEvent() " + "<br />")

     $MycheckBox

   #end

   ##   <input type="checkbox"
 name="IdEntry"
 value="${doc.fullName}"/> This is checkbox
 <br />

 </div>

      <span
 class="buttonwrapper"><input
 type="submit" value="Supprimer les entrées
 du flux d'activité"
 class="button"/></span>

  </form>

 {{/html}}

 ## get select events ID

 $request.getParameterValues('IdEntry')

 ## i want to delete these ID

 #foreach ($MyValue in
 $request.getParameterValues('IdEntry'))

   * try to delete this event with ID: $MyValue
 $MyValue.getPage()

   ## $MyValue.getPage() it doesn't work because
 $MyValue is not event anymore

   ## delete event method

   :-(

 #end

 **********************************

 To resume, do you have a way to give an event object to my
 deleteActivityEvent with form+velocity (because
 deleteActivityEvent accept only event object) ?
