Updating CV (delete entry which does not match the criteria any more)

Question

Hi,
A MV synchronises entries in a CV (MVtoCV) depending of a criteria (flag). OwnerShip=Meta view.
An MVentry is created.
If this MVentry doesn't match the criteria, not synchronized in the CV=OK
If this MVentry matchs the criteria, synchronized in the CV=OK
If this entry is deleted from the MV, deleted in the CV=OK
BUT
An MVentry is created.
If this MVentry matchs the criteria, synchronized in the CV=OK
if this MVentry doesn't match the criteria any more, the CVentry is still not synchronized=OK BUT remains on CV (my problem).
HOW to remove this entry automatically.
I tested with AttFlow and delete operation but without success.
Thanks for your help

Our approaches are actually the same. but BKBK goes further. The onMissingTemplate method will never fire in this case, as the page you're rewriting to actually exists, so what you're doing here is manually raising a 404. There are two ways of doing this; firstly you just do something like this:
<cfif FoundItems.RECORDCOUNT EQ 0 >
   <cflocation url="/404.cfm" addtoken="false" statuscode="404" />
</cfif>
This will let people know that they've entered an invalid URL, and the statuscode will tell search engines that there's no page there.
What BKBK is suggesting is perhaps being more intelligent. Rather than just throwing them at a standard 404 page, try and handle it a little better. In your page where you would normally show the results, try and find any relevant results. See if there are any keywords in the URL you can search the database for, and display the links to those products on the page. Nothing groundbreaking here, just something a little more "web 2.0" than just saying "no, there's nothing here".
The only difference would be that you want to do this:
<cfheader statuscode="404" />
...before then going on to display your page. This is purely for the search engines.
Hope that explains it a little.
