Can you post your project's .project

In the palette dialog (which knows nothing about GWT), we simply ask the system classloader for the class. If it throws a ClassNotFoundException, it does not provide any info about the actual cause.
That said, if your project is actually configured to use GWT Designer, GWT Designer will show you a compilation error in the source view
If that is not happening, we definitely need to see the entire project in order to determine why not.
