Hi again, thank you David for your explanation and your help.
But perhaps there is anyone out there that could check whether there is a mistake in the documentation/exemplification (mapfile and "URL query template"-Link) of the "Simple Point Query (mode=query), with pan/zoom" example of the "Mapserver Test Suite" like decribed in my email before. If there isn't any mistake in the example I would need somebody who could give me some advise how to manage to presever selected features selected (highlighted) even if I do some further zooming and pannig after the selection-procedure. Many thanks for your further help. regards Daniel -------- Original-Nachricht -------- Datum: Thu, 29 Jun 2006 08:21:03 -0500 Von: "Fawcett, David" <[EMAIL PROTECTED]> An: [email protected] Betreff: Re: [UMN_MAPSERVER-USERS] Test Suite > Daniel, > > To answer your first two questions, status on makes the layers available, > but does not display them.
