I've just started working with Flex and building a custom map. One of the things that I would like to accomplish is for the user to be able to display multiple popups at once for a layer. For example, click on a point display the popup window. Then click on a second point and display the information for that point at the same time. Right now, I'm only able to display one popup at a time. Is there a way to set how many can viewed at a given time?
