Normally I can figure out where exceptions are being thrown but this one is isn't so easy. I've got some pretty old code (see bottom of post) for creating a copy of a map used for pdf generation purposes.  For example, in order to create an 8.5x11 landscape pdf, I regenerate my current onscreen map in another offscreen container of the correct dimensions, then send that over to some AlivePDF routines to generate the ouput pdf. This has all worked fine with all AGS/Flex API's up to 3.0.  With 3.1 I get the following error sometime after the map copy in the new window is generated but before the map actually draws. TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.esri.ags.layers::Layer/updateLayerIfInvalid() at com.esri.ags.layers::Layer/updateDisplayList() at mx.core::UIComponent/validateDisplayList() at mx.managers::LayoutManager/validateDisplayList() at mx.managers::LayoutManager/doPhasedInstantiation() at mx.managers::LayoutManager/doPhasedInstantiationCallback() I know the above snippet is pretty generic but I'm not sure what else to post here.  The error seems to happen after the new container has the cloned map and right after I set the container.visible = true.  My guess is that there is something borked in the layers of the new cloned map but since I don't really have a good understanding of how the cloning stuff works, I can't go much further with that. This has always been a kludge process to get PDF's out of these maps and I've never been happy with this process but it is what it is and it's baked into my apps.  Basically, the cloning looks like this... I'm sure most folks have seen this setup before.  If there is a better way (besides the new map template stuff, which won't work for my needs), please let me know.  The below code creates a copy of the main app map, puts it in a bordercontainer and returns the bordercontainer with map.  That bordercontainer is put in a titlewindow, off screen and then sent to the AlivePDF generation stuff.     registerClassAlias("com.esri.ags.Graphic", Graphic);     registerClassAlias("com.esri.ags.SpatialReference", SpatialReference);     registerClassAlias("com.esri.ags.FeatureSet", FeatureSet);     registerClassAlias("com.esri.ags.Map", Map);             registerClassAlias("com.esri.ags.layers.ArcGISDynamicMapServiceLayer", ArcGISDynamicMapServiceLayer);     registerClassAlias("com.esri.ags.layers.ArcGISTiledMapServiceLayer",ArcGISTiledMapServiceLayer);     registerClassAlias("com.esri.ags.layers.GraphicsLayer", GraphicsLayer);     registerClassAlias("com.esri.ags.layers.Layer", Layer);             registerClassAlias("com.esri.ags.geometry.MapPoint", MapPoint);     registerClassAlias("com.esri.ags.geometry.Multipoint", Multipoint);     registerClassAlias("com.esri.ags.geometry.Polygon", Polygon);     registerClassAlias("com.esri.ags.geometry.Polyline", Polyline);     registerClassAlias("com.esri.ags.geometry.Extent", Extent);         //Generic Symbols     registerClassAlias("com.esri.ags.symbols.CompositeSymbol",CompositeSymbol);     registerClassAlias("com.esri.ags.symbols.Symbol",Symbol);     //Point Symbols     registerClassAlias("com.esri.ags.symbols.SimpleMarkerSymbol",SimpleMarkerSymbol);     registerClassAlias("com.esri.ags.symbols.PictureMarkerSymbol",PictureMarkerSymbol);     registerClassAlias("com.esri.ags.symbols.TextSymbol",TextSymbol);     registerClassAlias("com.esri.ags.symbols.InfoSymbol",InfoSymbol);     //Line Symbols     registerClassAlias("com.esri.ags.symbosl.LineSymbol", LineSymbol);     registerClassAlias("com.esri.ags.symbols.SimpleLineSymbol", SimpleLineSymbol);     registerClassAlias("com.esri.ags.symbols.CartographicLineSymbol", CartographicLineSymbol);     //Polygon Symbols     registerClassAlias("com.esri.ags.symbols.SimpleFillSymbol",SimpleFillSymbol);     registerClassAlias("com.esri.ags.symbols.PictureFillSymbol", PictureFillSymbol);         for each(var oLayer:Layer in map.layers)     {      if (oLayer is ArcGISDynamicMapServiceLayer)      {       var cLayer:ArcGISDynamicMapServiceLayer = deepClone(oLayer) as ArcGISDynamicMapServiceLayer;       //cLayer.addEventListener(Event.COMPLETE,onLoadDone);       printMap.addLayer(cLayer);      }           else if (oLayer is ArcGISTiledMapServiceLayer)      {       var tLayer:ArcGISTiledMapServiceLayer = deepClone(oLayer) as ArcGISTiledMapServiceLayer;       /* var cLayer2:ArcGISDynamicMapServiceLayer = new ArcGISDynamicMapServiceLayer(tLayer.url);       cLayer2.id = tLayer.id;       cLayer2.imageFormat = "jpg";       cLayer2.addEventListener(Event.COMPLETE,onLoadDone);       printMap.addLayer(cLayer2); */       printMap.addLayer(tLayer);      }            else if (oLayer is GraphicsLayer)      {       var gLayer:GraphicsLayer = deepClone(oLayer) as GraphicsLayer;       printMap.addLayer(gLayer);      }     }         printMap.lods = null;     printMap.scale = map.scale;     printMap.scaleBarVisible = true;     printMap.panArrowsVisible = false;     printMap.zoomSliderVisible = false;     printMap.logoVisible = false;     printMap.useHandCursor = false;          var mp:MapPoint=new MapPoint(map.extent.center.x, map.extent.center.y)     //printMap.centerAt(mp);     printMap.extent=map.extent;         return componentPrintBorderContainer;       deepClone function    private function deepClone ( obj : * ) : *                    {                            var bytes : ByteArray = new ByteArray();     bytes.writeObject(obj);     bytes.position = 0;     return bytes.readObject();    } ...

I've got several mxd's that I'm publishing with all their layers off by default and get the below error.  The services publish anyway but are stopped.  I simply start them and they are good to go.  I would be great not to get this error though.

At AGS 10.0x I have a map service that has an embedded WMS service in it.  The reason for this is because the WMS service is in a projection different than my data and other map services.  I put it in an mxd, re-project on the fly, and publish as a map service in the appropriate projection. Now, at 10.1, I can't publish a map service with any embedded layers that happen to be map/wms services themselves. I understand the performance issues in doing the whole embedded map service thing but at this point, doing that is the only way I can get certain data feeds into my web apps. I thought I heard that "there is a workaround" for this at the UC this summer.  Is anyone aware of what it might be? Conversely, I'm trying to get weather radar data from this site to overlay my map services, which are in state plane.  Does anyone know of a way to do that? Thanks much, -Royce ... View more

I've been attempting to cache a bunch of map services on 10.1 for a few weeks now.  Some complete in one shot, others take several attempts and even then, I'm not sure if they are complete or not.  The Caching status dialogue has yet to show results that give any confidence.  The "job Status" tab on the Cache Status details dialogue has jobs that are "processing" even though the servers aren't doing anything and I can't seem to cancel them.  I've attempted to run the "manage map server cache status" tool with no success (even though the tool reports "success" after completing).  After running that tool, I get "0.0% of the tiles are present" even though I can view the service in the JavaScript viewer and see that there tiles present.  I can even open the status.gdb fgdb and get all kinds of info.  Is it reliable? I'm very excited about where AGS 10.1 is going but wow, caching in 10.1 is like herding very temperamental cats.  You can view/manage caching related activities from the service itself (by right clicking the service in catalog), going to the "server" tools in catalog or interacting (to a certain extent) with the service in the web based manager.  There are tools for caching and reporting on caching and there are are services that do the same.  You can run the jobs synchronously (same as "wait for job completion"?) or asynchronously (why not just always async?) report status via map service, or not (I haven't figured that one out yet).  Each avenue has different UIs, capabilities, inputs, outputs, etc. Any insight into this tricky caching business would be helpful.  I've read through most (I think) of the online documentation but even then, there are enough "notes", "tips", "caution" and "legacy" statements that honestly it's hard to keep track of what the best path is. Also, it would be great to see what bugs have been reported/accepted but I can't seem to find any esri pages for that.  Esri, didn't you open that up a year or so ago? ... View more
