[Geomoose-users] Problem with query, GM 2.6

[Bistrais, Bob]

After trying a few things with no success, I shifted gears and went over to another application.  In this case, my query layer is a simple shapefile of townships in the state.  It has a field called TOWN, which is the town names.

I altered my mapbook.xml to point to the layer.  Now when I try the query tool on it, I get the message "CGI / FastCGI has encountered a problem and needs to close.  We are sorry for the inconvenience."

I have the error log at debug=5.  Here's the errors it returns-

Tue Jun 26 16:00:27 2012].335000 CGI Request 1 on process 4316

- I see the WMS/WFS set up and query line, but this is a Mapserver service.

One of your .map files probably references a symbol that is not in /maps/symbols/symbol.sym

This is QueryByPoint with a similar error, http://www.mapserver.org/errors.html#msquerybypoint-search-returned-no-results.
 Not sure if it is applicable to QueryByRect.

There may be some hints for the "Cannot evaluate expression, no item index defined." message in this thread, http://lists.osgeo.org/pipermail/mapserver-users/2010-February/064572.html

You may also want to up the level of debug output to 5 to get more detail, and look at the actual query sent to the datasource.
Sometimes seeing what is actually sent shows something obviously incorrect and then you can focus on why that parameter is incorrect.

HTH, Eli
