Hi all,
We have an Mapserver-Google mashup application with an OpenLayers
user-interface...
A problem arises when a user does a ITEMNQUERYMAP request on a feature
that is outside the map extent.
For example:
The first request below works perfectly: the map gets drawn, with the
"searched" feature highlited in red.
http://www.socioscope.qc.ca/wms/?map=nbcommalim_sr_01.map&layers=all&map_imagetype=png&QLAYER=nbcommalim_sr_01&QITEM=SRIDU&QSTRING=462032800&MODE=ITEMNQUERYMAP&mapext=-8244344+5679271+-8160264+5740420&map_size=840+675
The second request below DOES NOT WORK, because the "searched" feature
is OUTSIDE the mapextent. The following message then gets returned :
"msQueryByAttributes(): Search returned no results. No matching
record(s) found."
http://www.socioscope.qc.ca/wms/?map=nbcommalim_sr_01.map&layers=all&map_imagetype=png&QLAYER=nbcommalim_sr_01&QITEM=SRIDU&QSTRING=462032800&MODE=ITEMNQUERYMAP&mapext=-8193972+5717126+-8161869+5742924&map_size=840+675
WHY? Couldn't Mapserver simply return a map even if the query result is
empty? Am I missing something?
Thanks!
