I am trying to update a map application that was built using the 2.5 version of the Flex API to version 3.0. The problem is that data served by ArcGIS Server 10.0 does not display in the new application based on the 3.0 API. From what is posted in the documentation related to the 3.0 API it looks like configuring base and operation layers looks the same.
I know the map services delivered by ArcGIS Server are working because the 2.5 API version in Flash Builder displays the features. The 2.5 and 3.0 API versions of the application are both on the same Windows 2003 server, and both are loaded into Flex Builder 4.5.1. Both versions of the application are referencing the same ArcGIS Server map services.
Software used: ArcGIS Server 10.0 (feature server) Flex Builder 4.5.1 ArcGIS Flex Viewer 3.0 source ArcGIS for Flex 3.0 API agslib-3.0-2012-06-06.swc
A text file of the MAP portion of config.xml is attached.
