Robert, The 'all' issue appears to only happen when the 'Filter by Map Extent' is enabled. The queryExcute appears to fire twice. The results temporarily appear and then it fires again and wipes out the results. I will take a look at the Supports OrderBy Thanks, Paul

When a search option drop down is set to 'all' the results do not appear in the attribute table: Also, the 'Result Item Sorting' seems to remain disabled even when I have a layer that supports advanced queries capabilities.

Peter, I compared processing times between the Arcpy Flow Accumulation and Arc Hydro Flow Accumulation. They appear to be almost identical. The multi-processing algorithm sounds interesting.

‎04-07-2015

Any luck with using NumPy for Flow Accumulation?

If I add a non-spatial table to my AGO map is there a way to view it in Web AppBuilder? From my tests it will not show up in the layer list and the Attribute Table widget offers not options for viewing it.

I cannot get the Cut GeometryService to work properly in FireFox. It works great in IE and Chrome. Sample code is here: It is designed for cutting of polygons. You may need to adjust proxy and FeatureLayer when testing locally. <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=7, IE=9, IE=10">  <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>JavaScript API Cut Test</title> <link rel="stylesheet" href="http://js.arcgis.com/3.6/js/dojo/dijit/themes/claro/claro.css"> <link rel="stylesheet" href="http://js.arcgis.com/3.6/js/esri/css/esri.css" /> <style> html,body{height:100%;width:100%;margin:0;overflow:hidden;} #map{ padding:0; } #header{ font-size: 1.1em; font-family: sans-serif; padding-left: 1em; padding-top:4px; color:#660000; } .templatePicker { border: none; } .dj_ie .infowindow .window .top .right .user .content { position: relative; } .dj_ie .simpleInfoWindow .content {position: relative;} </style> <script src="http://js.arcgis.com/3.6/"></script> <script> var map; require([ "esri/map", "esri/toolbars/edit", "esri/dijit/editing/Cut", "esri/toolbars/draw", "esri/layers/ArcGISTiledMapServiceLayer", "esri/layers/FeatureLayer", "esri/tasks/query", "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol", "esri/symbols/SimpleFillSymbol", "esri/tasks/QueryTask", "esri/dijit/editing/Editor", "esri/dijit/editing/TemplatePicker", "esri/tasks/GeometryService", "esri/config","esri/dijit/editing/Union","esri/graphic", "dojo/i18n!esri/nls/jsapi", "dojo/_base/array", "dojo/parser", "dojo/keys","dojo/on","dijit/registry","dojo/_base/lang", "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!" ], function( Map, Edit,Cut, Draw, ArcGISTiledMapServiceLayer, FeatureLayer,Query, SimpleMarkerSymbol, SimpleLineSymbol, SimpleFillSymbol, QueryTask, Editor, TemplatePicker, GeometryService, esriConfig, Union, Graphic,jsapiBundle, arrayUtils, parser, keys, on,registry, lang ) { parser.parse(); // refer to "Using the Proxy Page" for more information: https://developers.arcgis.com/en/javascript/jshelp/ags_proxy.html //esriConfig.defaults.io.proxyUrl = "http://localhost/proxy/proxy.ashx"; esriConfig.defaults.io.proxyUrl = "/proxy"; var geometryService = new GeometryService("http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"); map = new Map("map", { basemap: "streets", center: [-96.541, 38.351], zoom: 13 }); var cutService; var unionService; var donutService; var waterbodies = new FeatureLayer("http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Hydrography/Watershed173811/FeatureServer/0",{ outFields: ['*'] }); var fieldsSelectionSymbol = new SimpleFillSymbol().setColor(new dojo.Color([255,255,0,0.5])); fieldsSelectionSymbol.setOutline(new SimpleLineSymbol("dashdot", new dojo.Color([255,0,0]), 2)); waterbodies.setSelectionSymbol(fieldsSelectionSymbol); map.addLayers([waterbodies]); function SelectionSet(geometries, tb) { tb.deactivate(); var selectQuery = new Query(); selectQuery.geometry = geometries; waterbodies.selectFeatures(selectQuery, FeatureLayer.SELECTION_NEW); } function PerformCut() { var selectGraphics = waterbodies.getSelectedFeatures(); if (selectGraphics.length == 0){ alert("Select a polygon to slice."); return; } else if (selectGraphics.length > 1){ alert("More than one polygon is currently selected.

I solved my issue, I needed to specify the template as an array.

‎06-13-2013

I get the following error in Chrome when trying to implement the PrintTemplate. Uncaught TypeError: Cannot read property 'showAttribution' of undefined I have showAttribution set to true for both my map and the print template. Any ideas? // create the print template var template = new esri.tasks.PrintTemplate(); template.layout = dijit.byId("mapLayout").value; template.label = "Test"; template.format = dijit.byId("imageType").value; if (dijit.byId("printLegend").checked){ template.layoutOptions = { "titleText": dijit.byId("mapTitle").value, "authorText": dijit.byId("printAuthor").value, "copyrightText": dijit.byId("printCopyright").value, "scaleBarUnit": dijit.byId("printScale").value } } else { template.layoutOptions = { "titleText": dijit.byId("mapTitle").value, "authorText": dijit.byId("printAuthor").value, "copyrightText": dijit.byId("printCopyright").value, "scaleBarUnit": dijit.byId("printScale").value } } template.preserveScale = true; template.showAttribution = true; //var printTaskURL = ndhx.config.printURL; var printTaskURL = "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"; // var printer = new esri.dijit.Print({ // "map": ndhx.map, // url: printTaskURL // }, dojo.byId("print_button")); ndhx.printer = new esri.dijit.Print({ "map": ndhx.map, "templates": template, url: printTaskURL }, dojo.byId("print_button")); ndhx.printer.startup(); dojo.connect(ndhx.printer,'onPrintStart',function(){ console.log('The print operation has started'); }); dojo.connect(printer,'onError',function(error){ console.log('The print operation has started'); }); dojo.connect(printer,'onPrintComplete',function(value){ console.log('The url to the print image is : ' + value.url); });

Further details: I installed/uninstalled the Web Adaptor a few times (IIS version). I followed the unregister direction from this post: http://forums.arcgis.com/threads/62254-Unregister-a-Web-Adaptor?highlight=web+adaptor During installation the web adaptor will direct me to a page for configuration. However, I got some 500.19 error (see attached). I was able to fix this by removing the configSections of the web.config file for the Web Adaptor. This was based on some online posts saying something is happening between .NET 2.0 applications and .NET 4.0 applications. My site is using only a 4.0 application so I am not sure why I got this error. However, I still get the error from the first post. I also tried a command line install and got a different error (see attached). I am not sure if something is not unregistering in the registry or a .NET 2.0/4.0 problem.

I get this error when using the new REST service link after installing the ArcGIS Web Adaptor (See attached).

The problem is I am looking for the nearest location on the polyline. The location may not contain a vertex. (see attached visual) Looping through each vertice and using your forumla would give me the distance from each vertice. But, that is not what I am looking for. The 'DistanceAsync' task gives me the distance, but for some reason I can't get the polyline nearest location. I would think the value for this would be exposed somewhere.

‎06-21-2011

How do I find the location on a polyline that is closest to another point on the map. For a visual of what I am looking for, in the attached PolylinePoint.png I want to obtain the yellow "Nearest Point' location. The geometry task 'DistanceAsync' gets the closest distance between a polyline and point. However, I am looking for that 'Nearest Point' location.

I think I figured it out. It looks like I was trying to deactivate it before it was active. I got it working now.

‎06-17-2011

I am working with a custom version of the Cut command on the editor widget and I cannot get it to deactivate: Dim editor As Editor = TryCast(LayoutRoot.Resources("SplitEditor"), Editor) If Not editor Is Nothing Then If editor.CancelActive.CanExecute(nothing) Then <--- This is never True editor.CancelActive.Execute(nothing) <--- This never fires End If End If '--- XAML <Button x:Name="btnSplitStreet" Style="{StaticResource MenuButton}" ToolTipService.ToolTip="Split Street" Command="{Binding Cut}" Click="btnSplitStreet_Click"> <esri:Editor x:Key="SplitEditor" EditCompleted="EditorWidgetSplit_EditCompleted" Map="{Binding ElementName=Map}" LayerIDs="GPS, Roads" GeometryServiceUrl="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer" />

‎06-10-2011

This post kind of helped me: http://forums.arcgis.com/threads/16710-BUG-SelectionCount-on-FeatureLayer?highlight=PropertyChanged+featurelayer Looks like I should us PropertyChanged event with the e.PropertyName ="SelectedGraphics". It is kind of troublesome with the event triggering multiple times for each selection change.
