I've found that none of the Sencha layouts are working correctly for me. The layout on initial page open is roughly correct, but nothing responds to changes in browser size.

As a simple test I've constructed a new Eclipse project (zztest) which just opens the Sencha CenterLayoutExample class. This works fine when viewing it as part of the overall Sencha demonstration (running from a web server on my own machine).

But in this simple test the CenterLayout widget opens up displayed in the horizontal center, but near the top. There is no response to browser re-size.

Watching with Firebug, no positions are changed on any of the elements as the browser size is changed (On the Sencha example the positioning values are re-calculated as the browser changes size).

It appears as if the browser.resize() event is not being passed to the layout system.

In brief my configuration is:
GWT 2.5
Sencha- gxt-3.0.1
Host page starts with: <!DOCTYPE html>
Inherits in xxtest.gwt.xmk: <inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.user.theme.clean.Clean'/>
<inherits name='com.sencha.gxt.ui.GXT'/>
The file war/zztest/reset.css is in place.

The gxt-3.0.1.jar is referenced both from the Java Build Path and the launch configuration.

I am not using Maven.

Can anyone see anything missing / wrong?
