I'm not sure why GWTP by default doesn't allow me to navigate directly to a place in my application by typing in the URL. What I mean by that is I can reveal a place by using
PlaceRequest request = new PlaceRequest.Builder().nameToken(NameTokens.savestatistik).build();
I solved it by removing
<inherits name="com.wallissoftware.pushstate.PushState" /> from my
*.gwt.xml file. Don't know what PushState even is but it seems to have fixed it.
