I have a publicly available WMS link that I'm trying to use as a layer in JOSM. It comes from http://dggs.alaska.gov/
When I load it in QGIS it connects to the server and there is a list of layers that I can add. When I try to load it in JOSM, there are no options of choosing layers, just inputting the link. I use 'add rectified layer' and enter the URL but no tiles are displayed.
