aha. we might have two of these bugs, but i'm getting this trace now. does anyone have any idea what line of code it is that is failing to print the stack trace for this NPE into the log? it looks like an NPE is causing the processing step to restart over and over again. would be a good fix to wicket to have it print that stack trace and not just the exception message.
