Dave, What does your result.html query template look like? Did you capitalize all the attribute names (as in "[ATT_NAME]")? If so, make them small caps for PostGIS tables--[att_name].
Also, here's another hint: Use the TOLERANCE keyword... http://mapserver.gis.umn.edu/docs/reference/mapfile/layer Or if you prefer a fancier mapfile reference, check http://umn.mapserver.ch/index_en.php Good luck! -Perry On Monday 27 March 2006 08:07, Dave Stone wrote: > I am having problems adapting the class-level query template technique in > Example 3.1 of the MapServer Tutorial. > > Essentially, I want to do as the tutorial example does, i.e. be able to > click on a point feature on the map, and have a query template open up and > display attributes for the point. > > The only significant difference between my setup and the example's (that I > can see) is that the example queries a layer (cities) whose data source is > a shapefile containing polygons, whereas my source is points in a PostGIS > view (dedloc).
