Hi, this is not an issue in the plugin but in josm-latest itself. For some unknown reasons, adding a new layer seems to empty the current dataset collection and all functions using getCurrentDataSet() returns a null value.

I'm not sure if it is related but I can reproduce it by using the "show/hide" layer button on the OSM data layer.
