I have a map service with several group layers, one group has 3 layers (2 polygon, 1 raster) and the polygon layers have labels. When I turn the group checkbox off/on in the TOC widget, all layers turn off/on including labels as expected. Problem occurs when I add both polygon layers to the <excludelayers> section in TOCWidget.xml. When I turn the group layer off (it's on by default), the features and labels disappear from the map (so far so good), but when I turn the group layer back on, the features appear but no labels. Turning the group layer on/off has no affect on making the labels reappear. Am using Flex Viewer 3.3 and ArcGIS Server 10.1.
