OK the sender appears to be working now, more or less, but I'm still lacking some
basics in the xwiki schema. I can't see in the eventlistener tutorial (or anywhere
else, apologies if it's somewhere I should have seen by now) where I should be putting
the groovy script that creates and attaches the event listener.
I've tried the two obvious places:
If I put it in the class of the object I want to listen to (i.e. the parent 'Task'
object) it appears to attach to the parent class (i.e. without any of it's data
attached), and if I put it in the template it doesn't appear to be attaching at all.
Any further advice? or any documentation you could point me towards on this?

I've switched to documentUpdatedEvent and tried to grab the instance method.
The code you wrote in your last email didn't work out of the box - it said the cached
'this.xwiki' object was null, so I changed to trying to get the xwiki object from
the context (which should be current when it's requested by the event handler, no?)
however the following code works OK when I save it from the object page, but hangs
interminably when I the onEvent method is called:
void onEvent(Event event, Object source, Object data)
{
def mailfrom = 'seth.redmond(a)gmail.com'
def mailto = xdoc.getStringValue('assignee')
def subject = 'xwiki done some stuff, yo'
def message = 'document '+xdoc.name+' has been changed'
def mailItem = new Mail(mailfrom, mailto, null, null, subject, message, null)
def xwcontext =
Utils.getComponent(Execution.class).getContext().getProperty('xwikicontext')
def myXwiki = xwcontext.getWiki()
def sender = myXwiki.getPlugin("mailsender", xwcontext)
sender.sendMail(mailItem, xwcontext);
}
It generally needs the xwiki to be killed so I'm not getting any errors I can work
with. Seems to be something to do with the plugin request, but I'm damned if I can
figure out what. Any sugestions?

http://lists.xwiki.org/mailman/listinfo/devs I seem to be running into an error I can't
find my way around when passing the xwiki context to an eventListener. According to the
error message itself (below) I appear to be passing the right objects, but I'm still
getting an exception thrown.
I should point out that I'm new to both xwiki and groovy, so I may have missed
something obvious, is the context not instantiated by the time it's been sent to the
event handler? or should I be grabbing it anew?
thanks

In general you should not cache the xwiki and context objects that you received here,
since they're probably going to be wrong at the time when events occur. Always get a
fresh reference to the context in onEvent, from the Execution instance. I know that you
got this code from the notification tutorial, but that one is a bit deprecated.
this.xwiki = xwiki
this.context = context
this.xwcontext = context.getContext()
this.xdoc = context.doc
}
String getName()
{
// The unique name of this event listener
return "mailing"
}
List<Event> getEvents()
{
// The list of events this listener listens to
return Arrays.asList(new DocumentUpdateEvent())
This event is deprecated, you should use org.xwiki.bridge.event.DocumentUpdatedEvent
instead
}
// Called by the Observation Manager when an event matches the list of events returned
// by getEvents()
void onEvent(Event event, Object source, Object data)
{
def mailfrom = 'seth.redmond(a)gmail.com'
def mailto = xdoc.getStringValue('assignee')
def subject = 'xwiki done some stuff, yo'
def message = 'document '+xdoc.name+' has been changed'
def mailItem = new Mail(mailfrom, mailto, null, null, subject, message, null)
MailSenderPlugin.sendMail(mailItem, xwcontext);
The problem is that you're trying to call a static method, but sendMail is an
instance method. You should get the right instance of the plugin using:
this.xwiki.getXWiki().getPlugin("mailsender", xwcontext)
}
}
// Register against the Observation Manager
def observation = Utils.getComponent(ObservationManager.class)
observation.removeListener("mailing")
def listener = new MailingEventListener(xwiki, xcontext)
observation.addListener(listener)
println "{{info}}Listener $listener.name is now registered on
$listener.events{{/info}}"
println "{{info}}Context = $listener.context{{/info}}"
println "{{info}}$listener.context.doc.name{{/info}}"
