Stuart, I'm unclear whether that "Caused by" line is in the same stacktrace or something entirely unrelated.
Can you send along the full stacktrace in your logs (either pasted in or attached as a file), and any other error lines that may immediate precede or follow it? It's easiest to debug what is going on if we have an full picture of all the errors (including the line numbers which appear in the full stack trace). If you've accidentally shortened anything, it may result in us overlooking the real cause. - Tim On 2/27/2013 11:00 AM, stuart.wood wrote: > Hi Tim, > > Thanks for the quick response.
