This should not be an issue, since '''''Tile.loadPlaceholderFromCache''''' can use the tile imagery data from zoom level 1 to populate the zoom level 0 tile. But the current '''TileController''' logic prevents this from working, since the '''''loadPlaceholderFromCache''''' method is only called for null tiles, but not after a server error." defect closed normal JMapViewer latest fixed
