Javascript function history.back(); is not working properly on google crome browser?

[Sagar]

In my project which is in gwt, history.back() not working properly in
google chrome , on other browsers like IE, Firefox and

Safari 4 it working properly.

In other browser when i logged in to application , then if i press
back button , it call onHistoryChange event with empty

token. ( i think which is a 1st empty token) in IE and FF.

But the same thing i tried on google chrome sometimes it not working
and when press back it will navigate to direct to login

page without firing onHistoryChange event. But sometimes it will call
onHistoryChange with empty token, And this is strange

behavior in chrome.

Please help me why this happened in Chrome, if anybody have any
solution or hack for this please post same.
