still going round in circles on this, I fear…
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 = '[email protected]'
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?
