View Full Version : GXT beta 2 and Chrome Book

24 Jan 2012, 5:09 AM

The new version of GXT didn't work with the Chrome OS, because the user.agent.os property isn't recognized and the application didn't load at all.
The chrome User Agent didn't contains the linux string.
This is an exemple of the chrome OS User Agent :

Mozilla/5.0 (X11; U; CrOS i686 9.10.0; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/ Safari/532.5

In the /com/sencha/gxt/core/Core.gwt.xml file, correct the properties provider :

<property-provider name="user.agent.os"><![CDATA[
var ua = $wnd.navigator.userAgent.toLowerCase();
if (ua.indexOf("macintosh") != -1 || ua.indexOf("mac os x") != -1) {
return "mac";
if (ua.indexOf("linux") != -1 || ua.indexOf("cros") != -1) {
return "linux";
if (ua.indexOf("windows") != -1 || ua.indexOf("win32") != -1) {
return "windows";
return "unknown";

That's the inconvenience of browser detection vs. feature discovery. An unfortunate choice of Google, closing the door to minor browsers. I suppose feature discovery is harder to do, or more cumbersome, in GWT...

This issue is still not fixed! Even Sencha GXT demos don't load on a Chromebook.

Can you verify that this works in the latest (support only) release of GXT 3.0.4 at http://staging.sencha.com:8080/examples-3.0.4/ ? Our OS detection changed to properly support 'unknown' OSes.

I have a commercial GXT 3.x license but not premium support. I thought I would still be entitled to download GXT 3.0.4 but I now can't log in to download it.

Commercial releases are located here > https://maven.sencha.com/repo/gxt-commercial-release but before you have access to them there, login here https://maven.sencha.com/repo. Let us know if you have an issue with logging in.

To further clarify, buying a commercial GXT license *without* support means you are allowed to use it subject to the terms of the commercial license, and doesn't mean anything about support. Buying support grants you access to our support-only bugfix releases, to SVN, to nightly builds, and gains you the ability to file support tickets and post in the premium help forums.

We have commercial license for GXT 3.X , but do not have standard support. When I logged in I am asked to buy support. So from where should I download latest GXT
