[rules-users] Re: Drools 4.0 problem: insert (drl) not reflected StatefulSession.

[Michael Waluk]

I found my problem, in case anyone else has this same issue (until
4.0.1which may have this fixed):

The ClassObjectFilter's accept method works like this:

    public boolean accept(Object object) {
        return object.getClass().isAssignableFrom( this.clazz );
    }

which is opposite of what I expected.  I want to find all the objects in
working memory that implement a particular interface.  So I created my own
ObjectFilter that works like you'd expect:

    public boolean accept(Object object) {
        return this.clazz.isAssignableFrom(object.getClass());
    }

Hope it helps someone,
Michael
