I checked a few other things.
In my loading html document, I've got the following line in the body
section to add history support:
<iframe src="javascript:''" id="__gwt_historyFrame"
style="position:absolute;width:0;height:0;border:0"></iframe>
Is this the correct location to have this?
I also just noticed that HistoryListener was depreciated, so I updated
to ValueChangeHandler. My main section is, for the most part:
public class entry implements EntryPoint, ValueChangeHandler {
public onModuleLoad() {
RootPanel.get().add(new MenuObject());
String initToken = History.getToken();
if(initToken.length() > 0) {
onHistoryChanged(initToken);
} else {
onHistoryChanged("Home");
}
History.addValueChangeHandler(this);
}
public void onValueChange(ValueChangeEvent event) {
onHistoryChanged((String) event.getValue());
}
public void onHistoryChanged(String token) {
Window.alert("Testing " + token);
}
}
When the page loads, a window appears alerting me to the name of the
token being loaded. This also occurs while refreshing. However with
the MenuBar that is displayed, the choice changes the token in the
URL, however no window appears. If I select Reload in my browser, the
page loads and the window appears.
I've gone back and looked at the previous tutorials I was using for
reference, but it appears that I've got everything. I could not find
anything in the Showcase example - it looks like I've got everything.
I'm using Chrome 4.0.302.3 dev, as well as Firefox 3.6 for testing.
By chance is there something that I'm missing?
