I have the same problem, and I am interested to understand how reridcting to the processing rather than the display avoids the issue. You will still be submitting data.
As already stated, using a hidden field requires that the hidden value be stored and validated which can be made generic but still has to be called explicity each time you want to save data.
Is there any other way to avoid this?
