Trying to compile (in 3.0) an ArcGIS Flexviewer widget that was created in v2.4 of the AGS api for flex, and receive a UniqueValueRenderer error as follows. Code is below also.
Encountered errors or warnings while building project DriveTimeWidget.mxml. DriveTimeWidget.mxml: Cannot resolve attribute 'attribute' for component type com.esri.ags.renderers.UniqueValueRenderer.
