Hi mandsch, Christoph and Michael :-),
i 've tested some mapserver WFS with the 2.6 branch.
I have to say that the gazetter module works very fine now.
I only got some troubles with the new jquery tablesorter module.
My error was caused by a misconfiguration with the output position numbers
which you can define in mod_wfs_edit.php.
If you don't set the columns to a correct order(without a gap),
the tablesorter module will not display any dataset that the WFS delivered.
Very cool feature,
now i can change over most of my WFS's to mapserver!! :-)
cheers marc
