I agree it's very strange! I've only tested it with the Firefox emulator. I just realized I have ONE physical device with a touch screen and a Firefox install, so I'm going to test it there. I'm glad to hear you couldn't reproduce, though! I'm thinking this is more a problem with the emulator than with the code. ... View more

Just curious if this is in 4.x now, or if I'm missing something. I do see several samples tagged with "TOC", including this one, but none that have the opacity slider. But I don't see anything about the legend in the layerlist properties or anything like that. Maybe I'm just not finding what I'm looking for? ... View more

Update for anyone struggling similarly to me, I got that method working: watchUtils.on(graphicsLayer, "graphics", "change", function (evt) { The reason it wasn't working was that I had graphics being added/created via app.MapView.graphics instead of the graphicsLayer. They are two separate containers! So the watch was working, but not detecting anything because I was adding graphics to the "wrong" place. Making sure each graphic creation took place within graphicsLayer did the trick. Of course, now I'm struggling to make sure I can detect creation of graphics from several methods. Search result graphics appear to be created in the app.MapView by default...I can override that, but then I need to customize each type. And it appears that featureLayer sources create additional graphics (probably in the app.MapView!) that I can't detect/clear!   ... View more

Dang. I don't remember what happened when I tried it in my code, which is a spaghetti mess of course. But I just tried it in the SketchWidget sample (clicking to create graphics is more like my use case) and it worked fine. watchUtils.on(graphicsLayer,"graphics","change",function(){ console.log("Graphics Changed!"); }); At least this confirms for me that I was on the right track with that methodology...now I just have to debug why it failed with my code at the time. Thanks! ... View more

I'm researching the same thing today. Haven't figured it out yet but hopefully will post here if I do.

Here's the entire script for anyone interested - obviously it's called by another script so a bunch of the specifics are refactored out.

I figured it out! Pretty much already had it in my code - referencing the request itself is pretty easy inside the "data" function. In this way, the original sort order can be set, AND the user can then sort themselves, but it still works with server-side functioning and more than 1,000 rows (which I had previously taken care of by the dataSrc function). I already had the first two lines, just added the d.orderByFields line:       data: function(d) { // this is where datatables add url params for server-side processing           d.resultOffset = d.start;           d.resultRecordCount = d.length;           //reference the request against the column array to customize the sort           d.orderByFields = colArr[d.order[0].column] +" "+ d.order[0].dir;           return d;       } ...

Yeah, I originally specified the ordering in the REST query but didn't like having to then mess with the native styles. Sorry I edited my original before seeing your response...if I do client-side, I am limited to the 1,000 features returned by the server. So yes, I'm trying to do that concatenation you mention, but I don't know how to "snoop" on the order requested by the user when creating that concatenation. I'm searching for examples of where the DataTables request can be self-referenced. ... View more

William, this is a great example. I'm currently struggling with getting DataTables to alter the AJAX request for sorting when my REST endpoint expects "orderByFields = <FIELD><ASC/DESC>", and DataTables just sends the two "order" params defined at https://datatables.net/manual/server-side  If I could somehow self-reference those options in the "data" function, I could customize the request and make it work. But your example makes me think you got it working WITHOUT customization. Maybe that's because you're not using the serverSide option and have less than the typical Esri REST-endpoint limit of 1,000 rows. Could you confirm that's true? Thanks --mike ... View more

Did you ever figure this out? I am working with 4.14 and the first time after a search the popup appears with no content. The second time through it works as expected. ... View more

Super cool. I logged in just to come here and say "thanks" for this solution - while I actually couldn't get it working I think I was only about a few steps away from getting it there. Since I created my popup at the same time as the MapView, I don't think the variable was quite right. BUT it led me to look at the Property Overview: Popup | ArcGIS API for JavaScript 4.14  And from there I saw that I could set  collapseEnabled: false, on the popup during construction, and achieve the same end result!

Jeez, found them. WHY does it always take ten (Google) searches to find stuff like this? Service output—ArcGIS REST API: World Geocoding Service | ArcGIS for Developers  ... View more

Yeah, none of the docs above are what I'm looking for, either. It's pretty easy to force a bad token so I know at least one error code out of the REST API: {"error":{"code":498,"message":"Invalid Token","details":[]}} but...seriously, there's no others? Pretty sure a timeout can happen too. Gotta be a list somewhere. ... View more
