Today while working on a custom JSAPI-based map viewer, my basemap suddently stopped appearing and my BasemapGallery stopped functioning.  By default, I have the World Topographic Map turned on, but now I'm just getting a blank screen.  It seems to have rendered my application unusable. When I load the MapServer page for the World_Topo_Map service, then click on "View In: ArcGIS.com Map", I get an error popup stating: The layer, World_Topo_Map, cannot be added to the map. Additionally, I attempted to load the Basemap Gallery Widget sample from the Javascript API samples page, and it appears to be broken as well. Is this happening to anyone else or am I just really unlucky?  Were there any changes made today to ArcGIS Online services that could be causing this problem? Thanks Jason ... View more

I've been working with ArcGIS Server 10.1 beta, prerelease, and now final (Red Hat Enterprise Linux, if that matters) for several months and have noticed the same issue with all three when executing ArcPy functions using the python interpreter packaged with the software (<AGS install dir>/tools/python). I have an ArcSDE 10.1 Enterprise Geodatabase on top of a PostgreSQL 9.0 database, and whenever I execute an arcpy function that imports data into the geodatabase, e.g.: arcpy.Append_management(...) or arcpy.MosaicToNewRaster_management(...) ...I get many lines of extra output as follows: ... column number 38 is out of range 0..37 column number 38 is out of range 0..37 column number 38 is out of range 0..37 column number 38 is out of range 0..37 column number 38 is out of range 0..37 column number 38 is out of range 0..37 ... The commands all seem to succeed, so I'm not sure where these messages are coming from.  Other than using grep or otherwise postprocessing the command output, is there any way to suppress these messages? ...

I am in dire need of the ability to apply a Classified Renderer to a Mosaic Dataset.  Specificially, I need to import Classified Renderer symbology from a layer file. My data is frequently changing and I need to be able to apply a color map that extends below & above the minimum and maximum values of my sample datasets.  In order to accomplish this, I had to use ArcObjects/ArcGIS Engine to create a ClassifyColorRampRenderer, apply it to a layer and export it to a Layer File, which was hard enough.  But now I can't even import said symbology because Mosaic Datasets don't support it!  Quite frustrating. I had a few hits when I searched the forums, and one post (http://forums.arcgis.com/threads/45727-Unable-to-use-a-classified-renderer-on-a-DEM-mosaic-dataset?p=159704&viewfull=1#post159704) indicated that this functionality would be available at 10.1. I am currently still evaluating 10.1 beta 2, and this functionality is still not available.  Has this been fixed for the 10.1 release candidate and/or will it be fixed for the final 10.1 release? A Raster Catalog *would* work for my purposes, since they support Classified Renderers, but for some reason ArcMap won't allow you to import symbology to a Raster Catalog layer from a Layer File!  Any info would be appreciated.

When using ArcGIS Online basemaps in the JavaScript API, for example: new esri.layers.ArcGISTiledMapServiceLayer("http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"); An invalid MIME type is returned from the arcgis online server.  Using Chrome Developer Tools, the following warning is returned for every tile request: Resource interpreted as Image but transferred with MIME type image/jpg: "http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer/tile/8/100/75". I believe the proper MIME type for any sort of JPEG/JPG image should be "image/jpeg", not "image/jpg".  Most browsers should be smart enough to interpret the image correctly, however it's quite annoying to see these warnings stack up in the JavaScript console. Has anyone else experienced this issue? ... View more

I initially posted this question in the 10.1 beta forum but thought this might be the better place for it. I'm having problems toggling the visibility of layers in a dynamically-drawn map service (10.1 beta 2) using the JavaScript API (versions 2.5 and 2.6 behave the same). I am following the sample described at http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples_start.htm#jssamples/map_explicitlayerlist.html. When I point my code to the sample MapServer given in the example ("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer"), which appears to be at version 10.0, the setLayerVisibility method works fine; however when I point the same code to my own 10.1 beta 2 map service (and modify the layer IDs accordingly), it ceases to work properly. Using the Service Editor, under Capabilities > Mapping, I've enabled "Allow per request modification of layer order and symbology," but this did not solve the problem.  The strange thing is that it seems to work partially, because my layer does appear when I first set its visibility (as long as I am at the initial map extent).  But when I pan or zoom, the layer becomes broken and does not redraw at any scale, and if I call layer.setVisibleLayers([-1]); to turn all layers off, the layer remains on screen. The DynamicMapServiceLayer displays fine if I specify the visible layer IDs in the ImageParameters property during construction, but as soon as I call setVisibleLayers() it becomes broken. Very strange behavior.  A bug in 10.1 or the JavaScript API I wonder? Jason ... View more
