Another pointer: The bug also depends on the Drools DRL package statement specifying the same package name as the Java declaration of the class that should be used as an event.
### OK ### package hashcode import hashcode.SimpleType declare SimpleType role(@event) end ### NOT OK ### package xxxxxxxxxxx import hashcode.SimpleType declare SimpleType role(@event) end So this *could* be related to the strange effect and/or bug in connection with declare for a Pojo required or not for use in a declare X extends Pojo. -W On 14 July 2011 12:21, Wolfgang Laun <wolfgang.l...@gmail.com> wrote: > On 14 July 2011 11:35, Mark Proctor <mproc...@codehaus.org> wrote: > >> On 14/07/2011 10:10, Wolfgang Laun wrote: >> >> On 13 July 2011 17:09, John <jfull...@progeny.net> wrote: >> >>> Interesting...
