We are actually seeing this in more than one case, I think. I've just managed to track down the exact debug statement that is causing the anomalous behavior in the first case we found.
There is no exception being thrown, and I haven't tracked down exactly how things are different, but our application behaves differently in both cases without throwing an exception.
The pipeline is attached. The only debug in the pipeline right now causes the app to behave as we except. If I take out that debug, I get different behavior. This pipeline is the xforms xpl for a page -- i.e. <page id="editTimesheetID"
path-info="/editTimesheet(.*)"
matcher="oxf/processor/perl5-matcher"
xforms="oxf:/app/xforms/edit/editTimesheetXForm.xpl" .../>
If it helps to download and execute it yourself, let me know. I have download stuff ready.

Hi Calvin,
There is 90% chance that this is an incorrect behavior. In most cases, when you see exceptions after removing a debug, it is because a processor is generating faulty SAX events. When you have a debug after the output of that processor, OXF internally creates a dom4j document. The dom4j library is quite forgiving and in most cases will create a valid document even if the SAX events are faulty, and then regenerate correct SAX events. Without the "debug", the events will go directly to the next processor, which might not be as forgiving (for instance Xalan will typically throw NPEs).
But we'll need to see your specific case to tell for sure. Can you please send us more info, like the exception, and if possible the pipeline in which this is happening?
Alex
