Re: [rules-users] expert: usage of ruleflow-groups
Hi again, Thank you for clearing that up. I didn't think it worked that way because i've tried it before and it didn't work. Anyway, according to what you're saying... * this is the stack as soon as i insert my objects: | MAIN | * this is the stack as soon as i setFocus on a specific agenda-group: | FOCUSED_GROUP | MAIN | (from left to right) * as soon as all activations from FOCUSED_GROUP fire, that agenda-group is popped out of the stack and the rule engine fires the remaining activations from MAIN Is this the way it works? I've tried this before with no success. I get rules firing from agenda-groups that *are not focused before* (besides MAIN, of course). Maybe this has something to do with the rules being declared in XML? Or some kind of bug?

Re: [rules-users] expert: usage of ruleflow-groups
Hi miguel, Did you try creating a new Drools Flow process with Rule Tasks inside it to isolate each specific set of rules. Then you can insert the facts into the working memory, start the process and the rules will be executed secuencially. You need to remember also that, if the rules are activated but the agenda group is without focus, the rules will never fire. 2010/5/4 Miguel Machado mls.mach...@gmail.com Hi there, I'm having some trouble implementing the desired workflow of rule firing in an application using drools expert.
