getCurrentDataSet() returns null after adding new layers (then null pointers exceptions)

[anonymous]

What steps will reproduce the problem?

1. launch josm (latest :2653) and load Vougy (74130) or something else in Haute-Savoie
2. You can select or draw ways (normal)
3. Ask for cadastr (F11) for Vougy (Projectino 4 zones, zone 2) 4 The cadastre come (ok) but you cannot draw oe select anymore ! 5 if (and only if) the cadatre layer is on top and hidden (unvisible), you can select or draw ?! 6 then you get this exception.

Please provide any additional information below. Attach a screenshot if
possible.

[pieren]

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.

see #4209 - it's the same error

(In [2668]) Fixed #4207 getCurrentDataSet() returns null after adding new layers (then null pointers exceptions); fixed drawing ways with real width
