This can be an issue with the spatial reference if the dynamic layer's spatial reference is different than the tiled layer's spatial reference. When you add the dynamic layer first, the tiled layer is not able to reproject. Tiled layers do not support reprojection, and will not be displayed if the Map's SpatialReference does not match the spatial reference of the tiled layer. If you add the tiled layer first, the dynamic layer will automatically re-project its map contents to match the map's spatial reference.
