I am aware that it would be better, and probably easier, to just create a WMA from scratch using Flex/Javascript and link it to our GIS server, however my work will not have access to ArcGIS Server for about 6 months. The reason I'm asking is that I would like to add some query possibilities to an incredibly simple WMA; I want the users to be able to search and select polygons based on for instance area (or 2-3 other attributes).
