Zoom to Selection Issues

[KevinLaughlin]

Hello All!

I'm new to Flex, so hopefully you bare with me here. I'm using the "Samples" Tab on the ArcGIS API for Flex in ArcGIS Resources to build a simple web application. Everything seems to function just fine except for the fact that the query never returns any results for parcels that I know exist.

As I state earlier, I'm new to Flex development, so I'm starting to spin my wheels here a little bit. I'm thinking it must have something to do with the <esri: Query> declaration, or the <esri: outFields>, but I cannot be sure.

Any and all help will be greatly appreciated and any advice for a novice to Flex would be even better.

Also, I'm using the latest version of Flash and Flash Builder, if that would help at all.

Thanks!
