Bumping this up again...  Or maybe I'm the only one here uses anything outside of AGOL/Dojo? ... View more

I'm wondering if you can you confirm or deny my theory: when selecting a mapped or local drive in the Catalog, ArcGIS Pro is enumerating the entire contents, killing performance, and displaying this thing for 5 minutes before I can proceed to navigate the folder structure. One explanation I received from an Esri representative on this issue was that disallowing connections to a drive root was for performance reasons.  The .NET Framework and Windows APIs (upon which ArcGIS Pro is built) provide FAST access to files and folders, what's going on here? ...

Upon further inspection, I can see that layers I have set to visible = false are still being loaded as a resource, and some like the Esri demographic layer are taking 2+ seconds to load.  Without knowing a whole lot about the JS API, I would say that based on what I see, setting the visible property to false doesn't actually do anything to lazy load or otherwise reduce the time needed to load a feature layer resource. ...

Thanks for the reply, I had a suspicion that setting the "visible" property to false was already doing what I was attempting to accomplish.  I had been tasked with making sure all the application resources are loaded efficiently, and was asked to explore if there's any improvement/benefit of attempting to lazy (or partially) load a feature layer, delaying any heavy lifting until after the user clicks the layer on/off checkbox.  But it appears that is already the case, so no need for me to reinvent the wheel here! ...

Thanks for the reply, this is an interesting implementation of a testLayer() function.  I'm giving this a try in my application right now! ... View more

Thanks for the helpful reply - I've implemented something similar and this appears to be what I need. ... View more

Unfortunately I do not have access to Esri tech support as this is for a personal project using the free version of AGOL.  I'm stumped by this because it worked fine for months up until Wednesday, then all of the sudden the errors started appearing.  I had made no changes to the web app or map recently. ...
