I have a custom WGS84 tile-cache in ArcGIS Server (which I didn't set up). This tile cache was creating using 256x256 pixel tiles, rather than ArcGIS Online's 512x512 pixel tiles. We have an existing ESRI-based Silverlight application that uses these custom tiles and ArcGIS Online's layers and it works great. I am porting this code to Flex, and discovered an issue. I can add either ArcGIS Online or our custom cache as the only layer in a map without a hitch. But when I try to add them both, only the first layer added (either ArcGIS Online or ours) appears / functions.
Is this a limitation of the Flex client? Or could there be something wrong with our conf.xml / LODs? If so, where can I find a "correct" WGS84 256x256 tiling scheme file that will work with ArcGIS Online?

Nevermind. I can be done. We had slightly different numbers in our conf.xml - not sure why. I extrapolated levels 0 & 1 from ArcGIS Online, fixed our LODs, and it works now.
