Hello, I wanted to start working with the GWT Designer. At the Beginning it worked in one project very well in my Eclipse Version 3.6.2. But in an another (maven) project, I get the following error:
WindowBuilder internal error WindowBuilder encountered unexpected internal error. Please contact support. java.lang.NoSuchMethodError: com.google.gwt.dev.javac.CompilationState.getTypeOracle()Lcom/google/ gwt/dev/javac/typemodel/TypeOracle; Show stack trace. Hide stack trace.

I've searched for this Error but found nothing in relation with the GWT Designer. I use the gwt 2.1.1 Version. I would be very happy, if anyone can help me. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
