I just noticed that even if the headercontroller widget is completely removed from the config.xml, there is still a white background placed in the headercontroller's original position.
My expectation was that the map would fill the screen without the headercontroller.
Attempted solutions: in the config.xml I tried top="0" & mapTop="0" with the map. First one causes a runtime error, second one is ignored.
Also, as an experiment, I hardcoded top="0" for <esri:Map in MapManagerSkin.mxml but still that white gap persists and the map will not go to application top=0 !!
Anyone know the source of this white space/container ??
Thanks
