[Chameleon] Querying LayersDarren.Cope@statcan.ca Darren.Cope@statcan.caTue, 16 Mar 2004 10:22:59 -0500

Hi Paul,
Yes, the layer names are in quotes. In the mapfile, it looks like the
following (currently with underscore, as this works):
LAYER # Start of Mailout Area
NAME "Mailout_Area"
STATUS DEFAULT
DUMP TRUE
DATA mailout
TYPE POLYGON
TEMPLATE "ttt" # this isn't used, but needs to be here for queries
TOLERANCE 10
TOLERANCEUNITS PIXELS
CLASS
NAME "Mailout Area"
COLOR 198 199 140
OUTLINECOLOR -1 -1 -1
END # Class
MAXSCALE 4500000
METADATA # Start of Metadata
WMS_TITLE "Mailout Area"
WMS_ABSTRACT "Mailout Area"
WMS_SRS "EPSG:42304"
END # End of Metadata
END # End of Mailout Area
In the context file, I have the following:
<Layer queryable="1" hidden="0">
<Server service="WMS" version="1.1.0" title="Mailout_Area">
<OnlineResource xlink:type="simple"
xlink:href="http://c137861.statcan.ca/cgi-bin/mapserv.exe?map=wms.map&"/>
</Server>
<Name>Mailout_Area</Name>
<Title>Mailout Area</Title>
<SRS>EPSG:42304 EPSG:42101 EPSG:4269 EPSG:4326 EPSG:42304</SRS>
<FormatList>
<Format current="1">image/png</Format>
<Format>image/gif</Format>
<Format>image/jpeg</Format>
<Format>image/wbmp</Format>
</FormatList>
<StyleList>
</StyleList>
</Layer>
If I use this exactly as shown, everything works as expected. If I put
double quotes around the Name in the context file, I get an error (the
images don't load at all...) So, this is possibly a bug in Chameleon, or do
you see something else wrong with what I am doing?
Thanks,
Darren

Darren,
Did you try putting the layer name in quotes?
NAME "provincial boundary"
I don't think that mapserver has any particular problems with this, but
perhaps there is a problem in chameleon and I would like to know.
Cheers,
Paul
