Re: What is the reason for the History.newItem(token) to invoke the onvaluechange(...) by default

Use History.newItem(token,false) to avoid firing the history event in the first part of your code.

Calling History.newItem(token)  cause firing of the history event...

I think its not the default behavior because its more likely that you use the history.newItem() method to actually navigate to a different place.

Actually when your whole app uses history tokens, then "clicking on the tab title" would not cause the tab panel to switch tabs itself but it would cause a history.newItem() and because of that new history token the tab will be selected later on in your ValueChangeHandler.

You could achieve this by adding a BeforeSelectionHandler to your tab panel. Inside the handler you can cancel the tab switch (event.cancel()) and create a new History item instead. Then the history mechanism you have implemented will do the tab selection everytime someone clicked a tab.
