I have found an internal error,
Caused by: java.lang.NullPointerException at org.apache.polygene.runtime.composite.TransientInstance.hashCode(TransientInstance.java:167) which should not be possible. Somehow the Mixins passed to the constructor in TransientInstance are all null. Investigating.... Cheers -- Niclas Hedhman, Software Developer http://polygene.apache.org - New Energy for Java
