Description
Hallo! It seems to me that the expression for classification of a layer is not evaluated for queryByRect or queryByPoint. See the following (constructed) case: I have one shapefile with the values "A" and "B" for the attribute "type" and an layer that shows only those of type=A (defined with CLASSITEM = type and an EXPRESSION in the corresponding CLASS). Querying the second layer leeds to results even containing shapes with type=B. This holds true for PHP/mapscript but also for a query by a WMS GetFeatureInfo-Request. I scanned the source code of mapserver 4.6 (the version I am working with) as well as of version 4.8-beta2. In both cases I couldn't find any place where the evaluation of the expression is done during a query. I also had a look an the bug-tracker an the mailinglist archives but couldn't find any hint. Have I overseen something? Silke P.S.: If necessary I can construct a test case which fails with the current version. P.P.S.: For the case that I have overseen something, here my full example of layer definition: # Landesmessnetz Menge LAYER DATA "/usr/local/httpd/gwmessnetz/data/messstellen/messstellen" NAME netz_menge METADATA "DESCRIPTION" "Landesmessnetz Menge" "RESULT_FIELDS" "invname, mkz, longname, brgort, tk25, arnum, bo_ident, projekt, auftrag, kommentar, bohrfirma, brgzweck, bohrz_von, bohrz_bis, bohrverf, xcoord, ycoord, xcoordo, ycoordo, zcoorde, zcoordb, invmbeg, invzbeg, invzend, strat, mesartmvp, foto, bewertung, bohrprofil" "RESULT_HEADERS" "Messstellenname, Messstellenkennzahl, Bohrungsname, Bohrungsort, TK25, Archiv-Nummer, Bohrarchiv-Ident, Projekt, Auftraggeber, Kommentar, Bohrfirma, Bohrungszweck, Bohrzeit von, Bohrzeit bis, Bohrverfahren, Rechtswert, Hochwert, Original-Rechtswert, Original-Hochwert, Endteufe, Höhe zu NN (GOK), Messpunkthöhe zu NN (ROK), Filtertiefe von, Filtertiefe bis, Stratigrafie, Messstellenart, Foto, Bewertung, Bohrprofil" END SIZEUNITS PIXELS STATUS OFF TOLERANCE 10 TOLERANCEUNITS PIXELS TEMPLATE void TYPE POINT UNITS METERS MINSCALE 1000 MAXSCALE 1500001 SYMBOLSCALE 100000 CLASSITEM mesartmvp CLASS NAME "Messstellen" EXPRESSION /,M/ STYLE COLOR 0 0 255 # blau MAXSIZE 20 MINSIZE 6 OUTLINECOLOR 0 0 0 # schwarz SIZE 12 SYMBOL "circle" END END END # Landesmessnetz Menge

Thanks for answer. Your suggestions (putting TEMPLATE void into the class definition) indeed helps. If you need help in constructing a test case please contact me.
