Is there a print complete event in ArcGIS JavaScript 4.x

DanielWebb — Fri, 30 Aug 2019 19:13:16 GMT

In ArcGIS JavaScript 3.x, there was an event for print-complete.

https://developers.arcgis.com/javascript/3/jsapi/print-amd.html#events

Does 4.x have that? Or is there a way to see when the print widget has completed?

I noticed the Print widget in 4.x has the method 'hasEventListener()' but I can't figure out how it works.

Thanks!

If you're using the print widget, you could read the state of the PrintViewModel, and when the print completes, the state should change to complete.

I am using the Print widget.

Would the same problem exist? It still needs an event finish in order for me to look at when the PrintViewModel changed status. What would the code look like for something like that?

Thanks!

Daniel,

Here's a bit of a workaround, because I don't know why the PrintViewModels state never changes to "complete".

      html,
      body,
      #viewDiv {

        height: 100%;
        width: 100%;
        overflow: hidden;
      }
    </style>

    <script src="https://js.arcgis.com/4.12/"></script>
    <script>
      require([

        "dojo/aspect",
        "esri/core/watchUtils"
      ], function(MapView, Print, WebMap, aspect, watchUtils) {
        var webmap = new WebMap({
          portalItem: {
            // autocasts as new PortalItem()
            id: "d6d830a7184f4971b8a2f42cd774d9a7"
          }
        });

        var view = new MapView({
          container: "viewDiv",
          map: webmap
        });

        view.when(function() {
          var print = new Print({
            view: view,
            // specify your own print service
            printServiceUrl:
              "https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"
          });
          
          watchUtils.when(print, 'viewModel', function(){
            aspect.after(print.viewModel, "print", function(deferred){
              return deferred.then(function(rslt){
                console.log("Print complete");
              });
            });
          });
          
          // Add widget to the top right corner of the view
          view.ui.add(print, "top-right");
        });
      });
    </script>
  </head>

Thanks Robert! That does the trick.

Actually, it doesn't work. The print would "complete" but when I click the link to the pdf it errors.

The link it gives is "<website>/undefined".

Daniel,

It works fine for me. Maybe you are unaware that the print server does not maintain the output file for an extended period of time. The Server deletes all files in the output folder at a certain age interval.

ArcGIS Server periodically deletes (or cleans) old unneeded files from the jobs, output, and system directories to prevent them from taking more disk space than necessary.

Directory	Cleanup mode	Maximum file age
jobs	Time since last modified	360 minutes (6 hours)

Server directories—ArcGIS Server Administration (Windows) | ArcGIS Enterprise

That's not it. I click the link as soon as the export is finished.

Daniel,

I don't get that at all on my end. Are you using your own print service or something?

Re: Is there a print complete event in ArcGIS JavaScript 4.x

DanielWebb — Thu, 05 Sep 2019 15:22:56 GMT

Yes, it's a custom print service

Re: Is there a print complete event in ArcGIS JavaScript 4.x

RobertScheitlin__GISP — Thu, 05 Sep 2019 15:27:23 GMT

Daniel,

I doubt this issue has anything to do with the code I provided. You need to get your print service issue figured out first.

Re: Is there a print complete event in ArcGIS JavaScript 4.x

Noah-Sager — Thu, 05 Sep 2019 16:20:40 GMT

Update: we will be updating the documentation for PrintViewModel.state values (complete is not working as Robert noted above) and consider adding a complete event to the Print widget at a future release.

Thank you to Robert for posting the workaround, and thank you to Daniel for bringing this issue to our attention.

I don't know. I keep trying other peoples' print services and get the same result. Do you think it's a print service setting somewhere?

Re: Is there a print complete event in ArcGIS JavaScript 4.x

RobertScheitlin__GISP — Sat, 07 Sep 2019 00:47:38 GMT

Are you having this issue when you do not specify a print service url and it defaults to Esri’s print service? If so then you have a internal network issue that is blocking something.

Re: Is there a print complete event in ArcGIS JavaScript 4.x

DanielWebb — Thu, 26 Sep 2019 17:33:13 GMT

Got busy with some stuff and this is the first chance I've had to circle back around to this.

Yes, it still does it with Esri print services. If I don't specify a 'printServiceUrl' it gives a message in the div "There seems to have been an error."

When I specified a url with this one (https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task), it did the same as before. It finished "printing" but would not open.

I'm not a network guy, nor do I have permissions to that part of our IT architecture. Is there a particular setting you think I'm missing? Do you think it's something in ArcGIS Manager or Portal?

I'll mark the code as answered. Thanks.

Daniel,

This is tough to diagnose as on my network using esri's print service I do not have that issue at all. Seems like your network is blocking something. Not sure what to tell you.

Noah-Sager — Fri, 18 Sep 2020 16:50:58 GMT

Double update: we will be adding a "complete" event to the print widget at 4.17 (early October 2020) that will make this all much easier to handle.
