I believe the difference between my application and this sample is that I have a VerticalLayout tag set for the application level of my application. I have a border container at the top, then the map, then another border container at the bottom which hosts an attribute table. If I add the <s:Image> in between Map and BorderContainer, I get another panel of the image and all white space to the right. I would like the image to overlay the map in a set location as in the sample above. How can this be accomplished? Is there some sort of override function for the layout that can be used?
I'm not sure if this is the correct way, but I solved the issue by removing the application level layout and using absolute layout positionnig for all the containters.
You could put your map and image in a layoutless container like group or border container. <bordercontainer> </bordercontainer> <group> <map> <image> </group> <bordercontainer> </bordercontainer>
