The most enjoyable part of any programming assignment is right near the beginning when you sit down with a pile of tools and resources and start hammering away at raw clumps of code. The more difficult part comes when you attempt to launch the application, only to watch that tightly-written code unravel into multiple late nights staring at a computer screen. However, all is not lost, as we have an excellent recommendation for you, which is the subject of this blog: the Console tab inside your favorite browser’s Developer Tools. Continue reading
This blog pertains to web maps and layer items that have both of these characteristics:
- Web maps and layers authored with ArcGIS Online prior to the June 2016 update.
- Contains polygon layers that are styled using Smart Mapping tools to adjust symbol size and/or outline width automatically based on scale
You also have the ability to automatically adjust the width of the outline of the polygon based on the current scale. Automatic sizing of polygon outline widths were also being represented using pixels rather than points.

What can you do if your web map was affected by this update?
If you created a web map or layer item in Online prior to the June update with layer styles that take advantage of automatic sizing based on scale, we recommend that you reauthor your web map. This process will resave your web map with the correct sizing values for consistent display in all ArcGIS clients. Here are the steps to reauthor your web map:
- Open your web map or layer item
- Click on “Change Style” in the layer menu for the polygon layer(s) that use automatic sizing of symbols. Note: You might want to write down the options you have selected so that you can easily reselect them in step 4.
- Select a different style for your symbols than you originally had selected and click “Done.”
- Click “Change Style” again on the same layer and reselect the original styling options you had, and click “Done.” Any options that were configured within the original style must be reconfigured.
- Save your web map or layer item. Your web map will now have size represented using point values.
For information on changing the style of your web map or layer item, see this help topic.
Note: this issue also occurs in web maps and layers that were created in Portal for ArcGIS and will be addressed in Portal for ArcGIS version 10.5. This article will be updated once a solution is available.
Functionality-wise, the app displays a 3D map with four widgets: Search, Zoom, Compass, and Attribution. By default, the View includes the latter three widgets, as described in the documentation. If you’re not familiar with the 4.x changes, all mapping apps contain a map and a view. The map holds the data, and the view contains the visualization information for that data. In other words, the map is the subject, and the view is the camera; complete with filters, modes, and settings. All 2D apps will have MapViews, and 3D apps will have SceneViews (note: the term ‘scene’ indicates three dimensions across ArcGIS). The same applies for maps from ArcGIS Online and Portal for ArcGIS: a WebMap is 2D, and a WebScene is 3D.
The previous version was 51.0.2704.63, and the fixed version is 51.0.2704.79.
Update, 27 May 2016: KB 13156 has been published on the Support website to provide additional information about this issue.

Beta versions of Esri vector basemaps are now available through ArcGIS Online as vector tile layers. These vector basemaps are accessible as both ready-to-use web maps and as vector tile layers you can add to a map. Additionally, vector basemaps include a variety of styles, some new … Continue reading
A proxy page stands between a server and an application. By using a proxy, you allow an application to authenticate on your behalf, bypassing a challenge and accessing secured services inside of an application. While the token is hidden, an application can access secured services with token-based authentication; a proxy handles massive post requests over 2,048 characters. Additionally, you can use a proxy when a resource and an application are on separate domains, as well as when cross-origin resource sharing (CORS) support is unavailable. Continue reading
The next release of each ArcGIS API and Viewer (for Flex and Silverlight) will be significant in that they are the last planned releases of two once-popular technologies. While technical support will be available for both APIs and viewers through June … Continue reading
