If was the different behaviour of Create which was confusing me  
originally.

In Update's current design it is validating, filtering and then  
validating again (using the same validator).  The first validation  
runs during input using AJAX, which is rather nifty and the feature I  
want.  If the second validation runs to protect the database is there  
is recommended way of determining where in the chain it is being  
called (so I can validate against RE{net}{IPv4} or /d+ resp.).

Thanks.
