That's exactly what *groups* are for (categories are for thematic grouping). Add both layers to the same group and they are treated as a single layer in the application.
Just make sure that they both have semantically similar and the same number of fields (RESULT_FIELDS) for query/identify. For the field headers (RESULT_HEADERS) in the application the ones defined for the first layer of the group in the map file is taken. armin On 14/06/2008 11:22, Mark wrote: > Hi all > > I am working on an application and was wondering if anyone has any ideas > for resolving the following problem.
