// FIXME
// For some reason cleaning mainController.openMaps just takes off the tabs content keeping open themselves.
// The workaround is to detect if map is cleaned and the clean the tabs by hand.
// For some reason the plain object binding does not work between tabs and mainController.openItems.
// Because of that, the cache openTabs map has been created and the binding is done by following listener:
mainController.openItems.addListener(MapChangeListener {
