Re: disable back button of the browser

Sorry, I just realized that I should have coffee before replying to posts.

I have looked at this one before. I came up with two solutions.

The first solution, is to implement your own "edit cache" within the session object. Your edit pages operate on this "edit cache" object. On form submit you simply move your edited object elsewhere and null the "edit cache" object. If the user then back tracks to the page, you can detect that the "edited object" is null and customize the response. This works for apps where you cannot commit objects to the database immediately on form submit (i.e. shopping baskets).

The second solution, to delete the page from backtrack store... I could not implement this one because I could never find the API into the backtrack page store. I know it lives in the WOSession but there doesn't seem any obvious way to access it. This would also involve overriding the handlePageRestorationErrorInContext(WOContext aContext) in WOApplication to implement custom behaviour.

do.Thanks in advance.
