java - how to get the last history token in GWT -

i want previous token of navigation.

for exemple, beingness in page:

http://www.example.com/com.example.gwt.historyexample/historyexample.html#page1

i redirected somehow new page :

http://www.example.com/com.example.gwt.historyexample/historyexample.html#page2

now if want current token, can way:

string currentplace = placemanager.getcurrentplacerequest().getnametoken();

currentplace receive "page2" can't figure how previous token "page1"

you can add together code illustration in onmoduleload() method or class created @ origin of application , of course of study not destroyed afterward

private place previousplace; private place currentplace; eventbus.addhandler(placechangeevent.type, new placechangeevent.handler() { public void onplacechange(placechangeevent event) { previousplace = currentplace; currentplace = event.getnewplace(); } });
