I'm working on a page that has some points drawn on it based on information out of a database table (not a map layer, I don't have access to a map layer for this data for technical reasons). I can display the points just fine. When I click on one, the code goes back to the server to load some slower loading data and displays the Popup InfoWindow with that information. In Chrome and Firefox, this works really well. I get a "searching" popup, and then the results appear when available.
In IE 11, I get the results display instantly, even before it's sent the request for the results. That means it doesn't show the results, since they aren't available yet. If I click the same point a second time, the results are there (as I assign them to the graphic's attributes).
Here's the relevant part of the code. I'd appreciate any suggestions on why IE is behaving so differently and what I can do about it. This is on 3.13 of the ArcGIS API.
Thank you.
