I'm trying to use <si:selectItems> and I followed all the hints in the example, but I still get an exception:

It seems that during validation the converter can't get a message. So I think I didn't setup your jars (1.1.1beta2) properly.

I placed the two jars to the \WEB-INF\lib directory of my war and included them in the Class-Path entry of the manifest for the war. Do I have to do something else?
