I'm pretty new to developer forums. If my question is best asked in a different venue, feel free to point me there. And if it's vague (see the full version below), please ask clarifying questions. Thank you! I was just reading in the 5.4 docs about traits, donning the isA keyword... pretty exciting stuff. It allows me a lot of flexibility as a rule-writer. But my company's upcoming implementation of Drools is going to feature Guvnor pretty prominently. (We're in the process of rolling it out.) Does Guvnor support traits? I should mention that I'm an analyst, and our developers are new to Drools and Guvnor as well. Traits are coming up in one of our early projects, as we consider whether to squish two similar things into the same fact type (so that we can easily use the same rules on both) or separate them out into two. -- View this message in context: http://drools.46999.n3.nabble.com/Does-Guvnor-Support-Traits-tp4018176.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Sure. So if I did author rules in Guvnor using traits, I would (1) write a technical rule to declare the trait, (2) write a technical rule to don that trait given whatever LHS pattern, and (3) write another technical rule to make use of the trait in a useful way -- all of which I would do without a GUI, but that's OK if I can handle some rules syntax. Did I get that right? Also, when I run test cases will Guvnor know what to do with the traits? (My hunch is yes, because the stuff behind the scenes is all the same.) Lastly -- again I'm a greenhorn -- does experimental mean you might abandon the feature, or just that it might need honing? By the way, in the etiquette, it just means not to send entire messages just to say "Thanks," right? I mean it's not just that programmers are so cranky they don't want you to be nice? :D -- View this message in context: http://drools.46999.n3.nabble.com/Does-Guvnor-Support-Traits-tp4018176p40...

"Experimental" means it has not been tested thoroughly yet, so it might be subject to improvements and even some language changes. Also, it means that the docs are really lacking! :) (shame on me!). I have never tried to use traits in guvnor yet, but my first impression is that you don't really need anything special. All the type declarations are managed with annotations, and the rules are transparent. 1) Consider that "declare trait X" can also be written "declare X @kind(trait)" 2) "donning" is a RHS action, you'd just need to write a "free" action 3) Trait types are compiled into interfaces, so you can just use them in the LHS exactly in the same way you'd use a declared class - i.e. to write patterns!. Feel free to contact me for feedback/bugs/requests/questions and let me know if you want to get involved!
