Hi list,
i am using the osgi-usable Guice-JAR-build
google-guice-snapshot-20081123.jar and the Multibinder extension
guice-multibindings-snapshot20081123.jar.
I would be pleased, if you could help me with following problem.
I get an exception, if I use following code line:
Multibinder<IModuleReporting> multibinder =
Multibinder.newSetBinder(binder(), IModuleReporting.class);
(At the bottom is the full code as attached)

IModuleReporting is a simple public java interface.
I tried a another simple example like:
protected void configure() {
Multibinder<IRep> m = Multibinder.newSetBinder(binder(),
IRep.class);
m.addBinding().to(Rep.class);
}
and
public interface IRep {
public void rep();
}
That works...but why not the other Multibinder?
Best Regards,
Michael Woelm
