Drools core 3.0.4 - Drools does not remove itself as a listener when Facts are Retracted
----------------------------------------------------------------------------------------
Key: JBRULES-542
URL:
http://jira.jboss.com/jira/browse/JBRULES-542
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Reteoo
Affects Versions: 3.0.4
Reporter: Edson Tirelli
Assigned To: Edson Tirelli
Fix For: 3.0.5
REPORTED BY TOM GONZALEZ:
---------------------------------------------
We are asserting facts that support property change listeners and found that Drools added
itself as a listener just fine but failed to remove itself when the facts were retracted.
We have fixed the stated problem by modifying org.drools.common.AbstractWorkingMemory as
follows:
Starting at line number 582:
protected void removePropertyChangeListener(final FactHandle handle) throws
NoSuchFactObjectException {
Object object = null;
try {
object = getObject( handle );
final Method method = object.getClass().getMethod(
"removePropertyChangeListener",
AbstractWorkingMemory.ADD_REMOVE_PROPERTY_CHANGE_LISTENER_ARG_TYPES );
method.invoke( object,
this.addRemovePropertyChangeListenerArgs );
