Just to clarify for anyone reading this, adding $useTable = false to
the model is not the solution. Mohammad mentioned that he was testing
"the situation in which DB is shut down" and how Cake would handle it.
I've just confirmed with 2.1.3 that the error page comes up ("Internal
error has occurred") but that the header in my view -- just before the
Form->create() line -- is displayed at the top of the page, just as in
Mohammad's example. So it seems like a buffering problem.
