Igor Vaynberg resolved WICKET-3352.
-----------------------------------
Resolution: Won't Fix
Assignee: Igor Vaynberg
this is not really a bug. we make no guarantees about ajax and history.
further, there is no other way, yet, to do a multipart upload properly without
an iframe, so we are stuck with this.
> Google Chrome 8 browser history and multipart form ajax submit

> Key: WICKET-3352
> URL: https://issues.apache.org/jira/browse/WICKET-3352
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5-M3
> Environment: Ghrome 8, wicket 1.5-SNAPSHOT
> Reporter: Ivan Vasilev
> Assignee: Igor Vaynberg
> Attachments: quickstart.rar
>
>
> The problem can be reproduced with Chrome and it doesn't exist in Firefox.
> With the attached quickstart:
> 1. In Chrome open localhost:8080, the Homepage (TestPage) is displayed
> 2. Follow the link and go to TestPageBrowserHistory page. In it there is a
> multipart form which is submitted via AjaxButton.
> 3. Submit the form several times.
> 4. Click the back button of the browser. In theory the browser should
> redirect to the Homepage, which was first opened, since the form has been
> submitted only via ajax. However the browser redirects to
> TestPageBrowserHistory instead of homepage.
> If the form has been submitted, for example, 3 times then the browser's back
> button needs to be clicked 4 times in order to go back to the homepage. Each
> form submit is added to the browser history.
> If the form is not multipart everything works fine.
> I checked wicket-ajax.js file and found the following:
> The multipart form is submitted by handleMultipart function. This function
> creates an iframe element and adds it to the dom tree. The form's target is
> set to the iframe. I think that by creating the iframe and adding it to dom
> tree, this is actually added to the browser's history and the described
> effect can be observed. Thanks.
