Description Radovan Synek 2011-12-08 10:08:54 UTC 
Created attachment 542456 [details]
maven web app

I have folowing Spring configuration (showing only relevant part):

<bean id="debug-wm-listener" class="org.drools.event.DebugWorkingMemoryEventListener" />       
<drools:ksession id="statefulSession" type="stateful" kbase="kbase1"> 
    <drools:workingMemoryEventListener ref="debug-wm-listener"/>
</drools:ksession>

Configured WM Event listener in knowledge stateful session by Spring. Expecting (at least) one WM Event listener:
statefulSession.getWorkingMemoryEventListeners().size()

but size is 0. 

See attachment:
build as maven project, then deploy to tomcat, open webapp in browser and click on the second link.

On first sight, looks like KnowledgeSessionDefinitionParser is forgetting to call AbstractKnowledgeSessionBeanFactory.setWorkingMemoryEventListeners(...)
Comment 2 Geoffrey De Smet 2012-01-12 11:34:30 UTC 
The problem is that the wrong DebugWorkingMemoryEventListener has been used.
Instead of:
    <bean id="debugWorkingMemoryEventListener" class="org.drools.event.DebugWorkingMemoryEventListener" />
it should be:
    <bean id="debugWorkingMemoryEventListener" class="org.drools.event.rule.DebugWorkingMemoryEventListener" />

I 'll adjust the code so it fails-fast when such wrong configuration happens.
