[Kenneth Skovhede, GEOGRAF A/S]

I see no problem with it.
The filter is bascially an SQL statement, so you can try changing the 
URL to:
http://localhost:8008/mapguide/test/KMLContentFactory.php?FILTER=FID>0 
<http://localhost:8008/mapguide/test/KMLContentFactory.php?FILTER=%22.urlencode%28$_GET%5B%22PropertyName>

Where FID is an existing numeric column.
