I tried to use EXT GWT with GWT 2.2.0 and had no success … no one told me I couldn’t do that.
Afterwards I found out there really is no accurate version requirement noted for EXT GWT. „GWT 1.5 or above is required“ from the helpcenter was not very helpful here.
What I started with and wanted to use was:
<!-- My Wish: From the Sencha Roadmap, not yet released: 3.0 -->
(maven Dependency configuration)
Which resulted in compilation errors:
$ mvn -Dmaven.test.skip package
java.lang.IncompatibleClassChangeError: Found interface com.google.gwt.core.ext.typeinfo.JClassType, but class was expected at com.extjs.gxt.ui.rebind.core. TemplatesGenerator$SourceGenerator.validateType(TemplatesGenerator.java:142) at com.extjs.gxt.ui.rebind.core. TemplatesGenerator$SourceGenerator.generate(TemplatesGenerator.java:97) at com.extjs.gxt.ui.rebind.core. TemplatesGenerator.generate(TemplatesGenerator.java:56)
I found some board entries about that. So I had to downgrade GWT and a couple of libraries like the maven gwt plugin, gin and gwt log. Thanks to maven this was less horrible than it could have been.
So, dear vendors, please make more accurate requirement definitions.
