Esteban Aliverti commented on JBRULES-2962:
-------------------------------------------
We are already working on this. The problem is that each time the agent compiles a
resource containing a declared fact type, a new instance of this fact type is added to
classloader (after all, declared fat types are converted to java POJOs internally). When
rules using these fact types are modified in the kbase (by modification I mean, a new
version is added), there is a ClassCastException because of the multiple definitions
existing in the classloader.
Could you please post the stacktrace to make sure that this is the problem? Try using a
KnowledgeAgentEventListener to get agent's errors.
Knowledge Agent rebuilding KnowledgeBase with scanner/notifier does
not work with declared facts

Key: JBRULES-2962
URL:
https://issues.jboss.org/browse/JBRULES-2962
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: drools-core
Affects Versions: 5.1.1.FINAL, 5.2.0.M1
Reporter: Ross Hall
Assignee: Esteban Aliverti
When reloading rules in a KnowledgeAgent declared facts will cause ClassCastExceptions
when new-instance is set to false. When new-instance is set to true, the KnowledgeBase is
rebuilt, however declared facts are not recognized and associated rules will not fire.
Rules not using declared facts will fire normally. Using POJOs works fine.
In both cases the KnowledgeAgent will build the rule base the first time, the issue only
seems to occur when the changeset resources are modified and are detected by the resource
notifier and scanner.
