  Hello again, thanks very much for all the help so far.
 I have an event listener which I have created as an xwiki component as per
 the instructions I followed previously. However my event listener while the
 code seemingly looks correct, is failing completely on one line.
 While I have put print line statements in to find the line that is causing
 the problem, I can't seem to find any output to show me why my line is
 wrong. I am almost certain it will be some kind of basic mistake and I am
 sure you fine folks could point it out almost immediately but it would be
 more helpful for me if I could find out why my code is wrong, so I can learn
 from it.
 How could I find out why this line is failing? Is there a log from these
 sort of failures in xwiki that I haven't found?
 Thanks very much again! 
Wiki components are quite hard to debug. However you should have indications in your
server logs.
Thanks
