Since moving to mapserver 5.0 (mostly to test AGG), a layer in my map file that has this class definition:
CLASS EXPRESSION (%qstring%) COLOR 230 230 179 END The query no longer works. If I change it to an explicit query string, like: EXPRESSION ('[DISTRICT]' eq 'ALTAMONT') The polygon is filled as expected. In the "MapServer 4.10 to 5.0 Migration Guide", there is mention that in the case of qstring queries, the qstring_validation_pattern layer-level metadata is required. It also says the absence of this setting produces a fatal error. My maps still work, they just do not fill in the polygon that matches the qstring. I cannot find any examples or documentation for the qstring_validation_pattern setting. Can anybody give me a pointer in the right direction? David S.
