What determines the order of popups?

Question

I have several overlapping polygon layers on my map, each with their own popup template.   I have a popup defined on my map as

var popup = new Popup({

markerSymbol: mySymbols.highlightSymbol(),

fillSymbol: mySymbols.highlightFillSymbol()},

domConstruct.create("div"));

map = new Map("mapDiv", {

infoWindow: popup,

basemap: "gray",

center: [-91, 38.2],

zoom: 7

});

When these appear on map click, I get all the selected features, but not always in the same order.  I would have thought they would appear from either top to bottom or vice versa in their drawing order.

Why is this and can I change it?

I'm glad that was enough of a suggestion to work with.  I finished the project I needed this for, leaving it as-is.  I'll have to dig back into that code and see if I can add this.  I didn't have just one layer that was important, I wanted the information from the layers to appear consistently, basically in the same order I had added them to the map.  The concept should still work, though, with modification to your code.

Good idea. I did some research and the onSetFeatures event looked like it might do what I needed. Here's a snippet of code that I used to re-order my features:

I never got a resolution myself.  I didn't attempt this idea, but I wonder if there would be a way to capture the information before it was displayed, reorder the sequence and then display.   I'm not sure what events you'd even be listening for.
