[rules-users] Updating the knowledge base manually...
Hi, I'm very new to Drools and don't know if this is possible, but i'm trying to manually update the knowledge base with the following steps : 1. Retrieve a knowledge builder from KnowledgeBuilderFactory 2. Load a drl rules file into builder 3. Create a knowledge base with the knowledge packages from the builder 4. Create a session from the kbase 4. Insert objects into the working memory => Activations are created 5. Fire all rules => Rules are launched , objects are created by rules and asserted into the WM 6. Retract objects generated by rules from the WM 7. Remove knowledge packages from the kbase 8. Generate another builder, load a different drl rules file and add the knowledge pacakges to the kbase => Activations are created automatically just after adding new packages but objects are created by rules and asserted into the WM. 9. Fire all rules -> Te agenda is empty , no rules are launched. Are the 8th and 9th steps the expected behaviour or i'm just doing something wrong ? Thanks in advance.

Re: [rules-users] Updating the knowledge base manually...
First of all, your approach does not sound like a good approach. If you are removing all rules and adding new ones, why not simply create a new knowledge base? Anyway, by default, drools fires all rules right after a rulebase is updated. To disable this behavior, you need to set a knowledge base configuration. Unfortunately setting this property now requires a down cast: KnowledgeBaseConfiguration conf = ... ((RuleBaseConfiguration)conf).setRuleBaseUpdateHandler( null ); I will add an option API to allow the configuration without the cast.
