I was trying to pass the selected features in the layer from the selection widget and the gp service widget was configured to interactively draw features. It didn't work because the selection widgets looks at the geometry type of the layer and then shows gp widgets where the input geometry match that type. Since I need points, lines and polygons I didn't specified a geometry type in the gp services and I think that is why it doesn't work.  However, I just changed from interactive to select a layer as input option in the gp service widget and now the widget displays all the layers and I can choose any of them and it works! I can also select features using a square icon that appears in the widget when you select a layer or even using the selection widget.  At the end I have created two gp service widgets: one with layers as input and another with interactive drawing features as inputs (since I didn't publish the gp service with a geometry type I can create and export points, lines and polygons) ...

Hi, I am looking for a solution to this too. I have created a gp service that converts points, polylines or polygons to kml, but I'm unable to use it to export features from existing layers because the option to add the selected features to the geoprocessing tool doesn't show up. ... View more

Thank you Randal! We ended up using the combobox to be able to add local data to the list. So, we kept it like that, but it is good to know the answer. ... View more

Thank you Robert, you were right, if I use symbolJsonUtils, I don't need to create the symbol again. I also had a small error assigning the symbology to the correct index in the options[] array. ... View more

Sorry, the context of the application is that I have a map with an ArcGISDynamicMapServiceLayer that has two dynamic workspaces defined. The application has two buttons, when I click the proj1 button, it reads three shp files and adds them to the service using the dynamicLayerInfos array. The shp files need a symbology, so I use the jsonSymbologies object to store a few symbologies in Json format. Here is the whole script (btw, I'm new to programming, so don't get too scared of the code) var map, usaLayer; require([   "esri/map", "esri/layers/ArcGISDynamicMapServiceLayer",   "esri/layers/DynamicLayerInfo", "esri/layers/LayerDataSource",   "esri/layers/LayerDrawingOptions", "esri/layers/TableDataSource",   "esri/Color", "esri/renderers/SimpleRenderer", "esri/symbols/jsonUtils",   "esri/symbols/SimpleFillSymbol", "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol",   "dojo/dom", "dojo/dom-construct", "dojo/dom-style",   "dojo/_base/lang", "dojo/query", "dojo/on",   "dojo/parser", "dojo/json", "dojo/_base/array", "dojo/dnd/Source", "dijit/registry", "dojo/ready",   "dijit/form/Button", "dojo/domReady!" ], function (   Map, ArcGISDynamicMapServiceLayer,   DynamicLayerInfo, LayerDataSource,   LayerDrawingOptions, TableDataSource,   Color, SimpleRenderer, symbolJsonUtils,   SimpleFillSymbol, SimpleMarkerSymbol, SimpleLineSymbol,   dom, domConstruct, domStyle,   lang, query, on,   parser, JSON, arrayUtils, Source, registry, ready ) {     //function init() {         parser.parse();

You can force a linear regression to pass through the origin of coordinates. The best way I have found so far it is to convert the raster to a numpy array, move the coordinate system so my origin of coordinates is the point I want to pass through, create a least square model using numpy.linalg.lstsq where Z = aX + bY + c and c = 0, and then use the model to create the raster. I'll let you know if it works. ... View more

Thanks Nathan, last time I did that I think I had to edit the windows registry, but this is much easier! ... View more

Hi, after some workarounds we found out that you need to include some code to check the license first. Just in case someone also needs it, this is the code that you have to add at the beginning: Dim pAoInit As IAoInitialize Set pAoInit = New AoInitialize pAoInit.Initialize esriLicenseProductCodeArcView Cheers, casti ...
