[Back on the list] Christy,
is the first argument to strConcat a string literal? Is it surrounded by string quotes? http://docs.geoserver.org/latest/en/user/data/app-schema/mapping-file.html#sourceexpression-optional http://docs.geoserver.org/latest/en/user/data/app-schema/mapping-file.html#cql There are a few other tricks like using strTrim(getId()) to turn source feature IDs, which are similar to strings but not quite the same, into real CQL-compatible strings: http://docs.geoserver.org/latest/en/user/data/app-schema/feature-chaining.html The geoserver-users list is a good source of CQL advice. Kind regards, Ben. On 14/03/13 03:08, Christy Caudill wrote: > And you were correct about the second error!
