accept-propagated-events doesn't affect script

In case that I set accept-propagation-events="false" on both action and script, the script is executed on the propagated event while the action is not executed.

According to jBPM Reference Guide, the script should not be executed.

. Default is yes|true. If set to false, the action will only be executed on events that were fired on this action's element. for more information, see Section 7.5.4, "Event propagation"

Actually, org.jbpm.graph.action.Script overrides org.jbpm.graph.def.Action.read() method and doesn't recognize "accept-propagated-events" attribute.
