Spring event type settings of EventListenersContainer do not work

In HST Spring configuration (normally META-INF/client-assembly/base.xml) an EventListenersContainer was set up.
When setting event-enabled configuration properties to false, still all the events are triggered.

For example, see the Hippo forge properties-demo project (http://forge.hippo-ecm.org/svn/properties/properties-demo/trunk) that has this:
<bean id="org.hippoecm.hst.core.jcr.EventListenersContainer" class="org.hippoecm.hst.core.jcr.EventListenersContainerImpl"
<bean class="org.hippoecm.hst.core.jcr.EventListenerItemImpl">
<property name="nodeAddedEnabled" value="true" />
<property name="nodeRemovedEnabled" value="false" />
<property name="propertyAddedEnabled" value="false" />
<property name="propertyChangedEnabled" value="false" />
<property name="propertyRemovedEnabled" value="false" />
When debugging, the PropertiesEventListener gets all events when editing a properties document.
