Re: [rules-users] Simple rule and Query

I'am using 5.2.0-SNAPSHOT using maven from https://repository.jboss.org/nexus/content/groups/public/ and i can't make it work... The query still return a size of 0... Can you share your entire project with me ?

Calling getQueryResults with a string not denoting an existing query returns an empty result set. I've updated the javadoc - thanks. -W 2011/4/14 DECOUX Yannick <yannick.decoux@ucm.be<mailto:yannick.decoux@ucm.be>> query numbers $a: Num( $b: num ) end Hi everyone, I'am still stuck with this simple example, anyone can tell me where to look or what I'm missing ?

This doesn't seems to be the case when I use a fake query name. I'am using drools 5.1.1 Any idea on this ?
