The main issue with your code is in the getParcelFromUrl() function. You are attempting to access a query property called 'parcelid' when the URL does not contain this query string parameter. Your code sets the window history to include an 'objectid' parameter.     Modify your getParcelFromUrl() function to access the objectid parameter:      //extract the parcel id from the url - new version using objectid      function getParcelFromUrl(url) {           var urlObject = urlUtils.urlToObject(url);           if (urlObject.query && urlObject.query.objectid) {                return urlObject.query.objectid;           } else {                return null;           }      } Also, note that this appears to be case sensitive so you will need to update the following line (101) from: window.history.pushState(null, null, "?OBJECTID=" + selection[0].attributes.OBJECTID); To (note the lowercase objectid parameter key): window.history.pushState(null, null, "?objectid=" + selection[0].attributes.OBJECTID); A working example is available here. ...

It looks like all of your map is being cached correctly - but there is an issue with transparent areas. If this was a caching issue then you end up with missing tiles that look more like this: Like jiang suwen says (above), try changing the tile format to PNG to resolve transparency issues. Also, check that the background colour of the ArcMap data frame is not black (Data Frame Properties > Frame (tab) > Background). ... View more

Instead of removing a single layer you could use the map.removeAllLayers() method to reset the map. This line: if (ct.loaded = 'true') {map.removeLayer(ct)} Becomes: if (ct.loaded = 'true') {map.removeAllLayers()} Owen ... View more

Hi Dorothy, When running a GP service on the server, the scratch workspace is created under a job directory. For example: http://[server]/arcgis/rest/directories/arcgisjobs/lotexport_gpserver/j52e4e3ec1ff741e9aad19b8263615232/scratch/WebMap_12345.pdf  You will notice that in the path a directory with a Global ID (j52e4e3ec1ff741e9aad19b8263615232) is created to ensure the output is unique. If you want to control where the file is created then you can export the PDF into this job directory then copy it into your target directory using python, for example: arcpy.mapping.ExportToPDF(mxd,fn,resolution=self.dpi,image_compression="JPEG",jpeg_compression_quality=90) shutil.copyfile(fn, r"{0}\{1}.pdf".format(outdir, key)) return r"{0}/{1}.pdf".format(baseurl,key) # Notes: # mxd = map document # fn = output filename (include the arcpy.env.scratchWorkspace path) # outdir = a path on the server for the output PDFs # baseurl = the virtual path to the outdir # key = unique file name Just make sure that your output PDF name is also unique. You can then return the URL to the PDF as the geoprocessing result. You may also need to implement some kind of regular spring cleaning for this directory. Scheduled tasks work great for this.

Your code accesses the map layer. To access field values you need to query features - not the layer properties. The first thing you will need to do is query the layer for the features that you want, check out: QueryTask: https://developers.arcgis.com/javascript/jsapi/querytask-amd.html Query: https://developers.arcgis.com/javascript/jsapi/query-amd.html Set the where clause on the Query to select your features ("TID" > 0 or "TID" = 0) then process your features in the response handling function. ...

The clip by polygon in the Data Frame Properties only prevents data outside the polygon from displaying on the map. If you want to delete the data use the Clip tool (available from the Geoprocessing menu). Note that you will need to use a feature class as the clip extent instead of a graphic polygon feature created using the Draw toolbar. The Clip tool is available at all license levels. ... View more

You can have multiple output parameters. For example, the following takes 2 input parameters then creates 4 output values: import arcpy n1 = float(arcpy.GetParameterAsText(0)) n2 = float(arcpy.GetParameterAsText(1)) out1 = n1 + n2 arcpy.SetParameter(2, out1) out2 = n1 - n2 arcpy.SetParameter(3, out2) out3 = n1 * n2 arcpy.SetParameter(4, out3) out4 = n1 / n2 arcpy.SetParameter(5, out4) Results: [ATTACH=CONFIG]34829[/ATTACH] Just make sure to set the Direction to Output in the Parameter properties when creating the script tool: [ATTACH=CONFIG]34830[/ATTACH] ...

Check out this example: http://jsbin.com/hobomode/2 I just added your JavaScript to the selectParcel() function in the ESRI sample: function selectParcel(parcelid) { if (parcelid) {   var query = new Query();   query.where = "PARCELID = '" + parcelid + "'";   var deferred = parcels.selectFeatures(query, FeatureLayer.SELECTION_NEW, function (selection) {    var center = graphicsUtils.graphicsExtent(selection).getCenter();    // add parcel to browser history    var apn = selection[0].attributes.APN;    if ((typeof history.pushState !== "undefined") && (apn)) {     window.history.pushState(null, null, "?getParcel=" + apn);    }    var extHandler = map.on("extent-change", function () {     extHandler.remove();     //zoom to the center then display the popup     map.infoWindow.setFeatures(selection);     map.infoWindow.show(center);    });    map.centerAt(center);   }); } } ...

Hi Todd, Try this method using a python list to store the input feature class names: # Set you parameters (e.g. change to use tool inputs) gdbInputs =  r"c:/temp/Inputs.gdb" gdbRoutes =  r"c:/temp/Routes.gdb" # Create inputs list arcpy.env.workspace = gdbInputs inputList = [] fcList1 = arcpy.ListFeatureClasses() for fc in fcList1:     inputList.append("{0}/{1}".format(gdbInputs,fc)); # Switch workspace (if required) arcpy.env.workspace = gdbRoutes for inputFC in inputList:     # find your second feature class based on the last 6 digits     targetFC = "{0}/Route{1}".format(gdbRoutes,inputFC[-6:])        # run your other processing with inputFC and targetFC     print "Input FC: {0}".format(inputFC)     print "Target FC: {0}".format(targetFC) Owen www.spatialxp.com.au ...

I haven't tried this using silverlight but I think all the ESRI web APIs would need to pass a GPFeatureRecordSetLayer object to the server for geometry objects - more information is availabe here: http://resources.arcgis.com/en/help/main/10.1/index.html#/Using_geoprocessing_tasks_in_web_applications/0154000004v8000000/ Also, check out the message in a bottle sample at: http://resources.arcgis.com/en/help/silverlight-api/concepts/#/Geoprocessing_task/01660000000n000000/ The message in a bottle sample uses a point but you should be able to substitute this with your polygon or graphic input: List<GPParameter> parameters = new List<GPParameter>();     parameters.Add(new GPFeatureRecordSetLayer("Input_Polygon", poly));     ...any other tool parameters...     parameters.Add(new GPDouble("Other_Input", Convert.ToDouble(DaysTextBox.Text))); Owen www.spatialxp.com.au ...
