could you post some code, preferrably a runnable test? That would be the best way to explain exactly what you're doing.
thanks for answering.
By providing the sample code, I realized my mistake: I had a base listener class (marked with @Listener) and a subclass of this base listener class which was also marked with @Listener. This had the effect that annotated methods in the base class hat no effect....
After I removed the @Listener annotation from the subclass everything works fine...
