In my application I'm using basemap gallery widget for the user to switch between basemaps. However, when the basemap has been switched the map.getBasemap() keeps returning the original basemap assigned to the map in the constructor instead of the current basemap.
Also map.getLayer(map.basemapLayerIds) returns undefined after the basemap has been changed by the basemapGallery widget.
How can I return the reference of actual current basemap which is displayed in the map?
This will show you what the current basemap is

var basemap = basemapGallery.getSelected();. Note that some basemaps consist of two layers (Imagery with Labels and possibly Terrain with Labels).
