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
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.
