Re: [rules-users] No rules loaded when reading package from Guvnor
@Michael, yes, Geoffrey merged it. I couldn't finish the test I was preparing because I need to finish some stuff first :(. The fact that mvn test -Dtest=Whatever is not working is also making my life miserable :) Best Regards, Esteban Aliverti - Developer @ http://www.plugtree.com - Blog @ http://ilesteban.wordpress.com On Thu, Nov 17, 2011 at 2:43 PM, sgo simon.gou...@elca.ch wrote: Confirmed.

Re: [rules-users] No rules loaded when reading package from Guvnor
Thanks for the quick replies. @Esteban: - Yes the rules do appear when accessing the package source published by Guvnor - Yes the package is built; for my understanding wouldn't trying to load an unbuilt package from its URL generate an error? @Michael: Yes this is the right track... I created an alternate session without Spring by simply loading the package from the URL with a KnowledgeBuilder, it worked (the rules were there).

[rules-users] No rules loaded when reading package from Guvnor
Hello all, I'm a semi-beginner with Drools and am having an issue I haven't found reported elsewhere. I have a package defined in Guvnor, with model imported from JAR, one global, a dozen rules and a couple of test scenarios. The package is loaded from the binary published by Guvnor via a knowledge agent into my stateless session (defined in Spring beans), but no rules ever fire. (Note that rules do fire as expected in my Guvnor test scenarios.) When investigating in debug mode, I see the package is properly loaded, with imported type definitions and global, but no rule is in there! The package's rules table is empty and I really have no clue why (I initially thought my rule definitions could be the cause and created a minimal test package with just one simple rule but with no success.) Could anyone point to possible causes for this? Many thanks in advance.

Re: [rules-users] No rules loaded when reading package from Guvnor
To help isolate the problem, what happens if you try the same but without Spring? i.e. You use the KnowledgeAgent to retrieve the package from Guvnor, create a session, insert facts, fireAllRules etc?
