Zoom to Selection Issues

KevinLaughlin — Tue, 17 May 2011 13:47:56 GMT

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!

Hi Kevin,

Probably better to post your question here: http://forums.arcgis.com/forums/18-ArcGIS-API-for-Flex

If you ever dive into the JS API, please come back and we'll be glad to help :).
