Re: [rules-users] Re: Pattern matching

Very interesting. I tried it too , I dont think its about the '==' because it seems to be working for eval( reason == 'override'). So it is more to do with having the eval method call. Nice find. Not too sure if this is a bug, or if there is a reason why drools works this way.
