Changing history token from external js

[Phil McDonnell]

I have a GWT app that is wrapped in an iframe within a base html page. I'd like to add a few navigational links (not actual links, but js powered ones) in the outer html part of the page that allow me to change the state of the GWT app.  I was thinking that I could change the src attribute in the iframe that wraps the entire GWT app to navigate to a desired history token.

Is this a good idea? Is there a better way to do this navigation from outside gwt, apart from putting everything in gwt?

Thanks,

Phil

I'd rather expose a method in GWT and call it from the parent page.
