Developing with Ext GWT: book samples

[csergiu77]

I recently bought the Developing with Ext GWT: Enterprise RIA Development
but unfortunatelly samples does not work with Ext GWT 2.0 RC2 SDK

I managed to fix some of the samples but samples from latest chapter the one with
sample application NO;

It works partialy on hosted mode but not otherwise.

In compliled mode i get this :[ERROR] Unexpected internal compiler error

I solved the problem by adding this to my classpath
gwt-dev-patch.jar.

But is this a gwt problem or an ext-gwt related problem ?
And what cause this ?

It is a gwt problem and will be fixed with the next gwt release
