Hi!

Please take a look at my programm and the exception:

[westnordost]

So the source exception is at de.westnordost.osmapi.map.MapDataParser.onEndElement(MapDataParser.java:164)

handler is null. This should be the expection you get if you pass null for the handler in mapDataDao.getMap

thanks a lot; I supposed null be never got
