AH!  *So*, the theory here is that I am generating more than the 8kb of
data, which is being autocommited to the browser, then an error occurs and
the servlet cannot send the error, but instead raises this exception.  Got
it.

In fact, I write a large form back in html.  If the last element were to be
null, and I try to write out a value thus:

<%= myObject.myProperty %>

then I would get this error as the servlet cannot raise a null pointer
exception as it would generally do.  Is that right?

I shall try this today, as it may well explain everything.

Justin.
