[Mapserver-users] savequery

[Steve McCrone]

I'm using mapserver 4.0. I sue a javascript function to test finding a
lake - see my hidden values & function below.

I set the savequery="true", and the query file (eg.DEMO10783178743172.qy)
does get saved in the tmp directory. However, when I interact with my map
again, say "zoomout", the highlighted border around the lake polygon
dissapears. I wish to keep it there until the user clears it using a
javascript function.  Does it have anything to do with the MAP_IMAGETYPE?

Thanks,

Steve

function findLake(){

 document.mapserv.mode.value = "itemquery";

 document.mapserv.qlayer.value = "LAKE_QUERY";
 document.mapserv.qstring.value = "BOWSTRING";
 document.mapserv.mapext.value = "shapes";
 document.mapserv.buffer.value = "1000";

 document.mapserv.submit();
