I have a requirement to generate map images with polygons symbolized on data from an external source.  The source is a REST API.  The REST API is fairly elaborate and changing it is not desired.   I'd like to make a SOI which when requests are made against the MapServer will query the external API, get some more data, mash it together with the geodatabase data, then return the image.  The image needs to be symbolized based on values from the external API.   Does this sound reasonable through a SOI?  I've seen an example which adds new fields from an external database which looks close to what I want to do.  https://youtu.be/gYmFarHEMgw?t=2639 In order to follow this example, but also symbolize, would I need to symbolize on an existing field in ArcMap and change the values of the field used for symbology with the SOI rather than add a new field? Do I need to use an SOE instead of SOI if I'm interested in adding parameters to the request?  As in I want to get the image, but with parameter A make call A to the API turning all the polygons red, with parameter B call B and turn all the polygons blue. Some other options have been considered and rejected.  Pulling the data from a feature service and the REST API and combining the data client side is not desired. Thanks! ... View more

I'm building an Attribute Inspector for an application.  The application allows the user to click on a feature (displayed from a feature layer) and edit the attributes of that feature.  I'd like to add some additional inputs to the Attribute inspector which will not be populated by fields of that feature.  Is there a tidy way to do this using api methods or is it going to be done with lower level dojo and html manipulation? What I'm imagining is something like this sample Query and edit related records | ArcGIS API for JavaScript 3.21  except that I'd prefer not to build the whole content.  I'd like the content to be built from the layerInfo like this example Using the attribute inspector | ArcGIS API for JavaScript 3.21  and then modify it.   If I have to build the additional controls up from dojo objects that's ok.  Ultimately what I'm attempting is to click a feature, show it's fields, get data from another feature, show some of it's fields and allow them to be edited (ideally with all the validation and domains associated with that field) while it looks like one feature to the user.  For external reasons the attributes can't be on the same feature class / table and there is no relationship class between the two feature layers.

Are there any samples out there for creating a custom address locator?  I'd like to build something that wraps in a web service, does some point in polygon searching to populate some fields, etc.  Ideally it'd be something in dot net, but I'd take anything if its out there. Thanks ... View more

I'm attempting to enable popups on layers in an ArcGISDynamicMapServiceLayer programmatically.  Ultimately I'd like to move this code into the LocalLayer widget.  I've gotten something working for feature layers, but I'm struggling a bit on layers within MapServices.  I'm digging into LayerInfoForDefaultService.js now and am trying to figure out the path.  It looks like you can't call enablepopup() on those layers until they have infotemplates loaded.  I'm going to try including an infotemplate in the locallayer configuration.  I'm hunting through the code that is called when I hit the dropdown for the layer for the first time (it appears to populate the info template at that time if it's blank).  Does anyone have any sample code or suggestions / experience with attempting to do this same thing?  Even if you've attempted and gotten stumped it could be helpful.

Has anyone attempted to have live display of line segment and total lengths while editing?  I want users to be able to create a feature of very close to a specific size by seeing the measurement while drawing.  There have been enhanced widgets in the past with this function displayed live on the line, this example https://community.esri.com/thread/158226 does measurements and displays it in the widget.  I'm mostly trying to figure out where best to sum up the measurements and can worry about where to display it second.  I'm trying to build it into the javascript viewer. Thanks! ... View more

I've been successfully using the Local Layer widget and it's been working great.  Lots of layers and great functions, I've even been able to use some additional layer types with it.  Is there any reason I shouldn't be using it?  Is there any reasonable argument for keeping everything through a web map instead of adding the services / layers directly?  I've had its use questioned and was looking for any discussion as to why one way or the other may be "better". ...
