Browser.setUrl() creates duplicate requests [message #1736672]

We're in progress to migrate from RAP 2.3 to 3.1 and encountered some strange behaviour of the Browser-Widget.
We used the Browser to download files as described in RAP FAQ and it worked fine so far. After upgrading to RAP 3.1 the following code produces two requests to the given url. Inspecting the network traffic in Chrome developer tools the first one is shown as canceled.

Browser browser = new Browser( parent, SWT.NONE );
browser.setUrl(RWT.getServiceManager().getServiceHandlerUrl( "downloadServiceHandler" ));

This behaviour is reproducable with any url (here: www.google.de), the network requests are shown below
index.php/fa/26315/0/

We see a strange request with status cancelled (marked red).

Unfortunetely we can not just ignore the first cancelled request because in our case of a request to a service handler the handler is called twice.

This behaviour applies to Internet Explorer (11) and Chrome (51), we could not reproduce it wit Firefox (47).
I've created a sample project wich demonstrates the error.

Does anyone have similar issues or knows a solution?

Hi there!

We're having the same problem using RAP 3.1.1. Did you find any solution to this so far?

IMHO this was fixed in RAP 3.1.2.

we solved this with settext of browserwidget and filedownload jquery plugin.
It seemed to be much more stable even on mobile devices

<html><head>
<script src='/plugins/jquery-1.8.3.min.js'></script>
<script src='/plugins/jquery.fileDownload.js'></script>
<script>
$( document ).ready(function() {
$.fileDownload(' + url + ');
});
</script>
</head><body></body></html>
