[rules-dev] KnowledgeBaseEvent on KnowledgeAgent

[Steve Ronderos]

Hi Ben,

The kbase that is passed into KnowledgeAgentFactory.newKnowledgeAgent is 
used to configure the KnowledgeAgent that is created.  The 
KnowledgeAgentFactory reads the current contents of the KnowledgeBase and 
the configuration of the KnowledgeBase and ensures that future 
KnowledgeBases are set up with the same configuration.

This is useful for setting properties that are specific to a KnowledgeBase 
which you can not set using the KnowledgeAgentConfiguration class.

Please note the differences between the configuration options on the 
following 2 interfaces:
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/apidocs/org/drools/KnowledgeBaseConfiguration.html
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/apidocs/org/drools/agent/KnowledgeAgentConfiguration.html

I believe the reason why your rules are not executing when you get a 
session from the kbase that you provided to the KnowledgeAgentFactory is 
because the kbase provided to the KnowledgeAgentFactory is not modified 
when the agent is built.  Once the agent is built you should use 
agent.getKnowledgeBase().newStatefulKnowledgeSession()

You can read more about how to configure KnowledgeAgents in the 
documentation section 3.2.6: 
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/html/ch03.html#d0e1123
The details I mention above are in the text between Example 3.20 and 
Example 3.22.

Hope this helps,
Steve
