Hello,
i'm using the latest version 5.1.1 of drools-flow for a POC project.
I have a process definition where I have an intermediate event node within a
foreach CompositeNode.
When I trigger the event using processInstance.signalEvent() I get a
ClassCastException:
java.lang.ClassCastException:
org.drools.workflow.core.node.CompositeContextNode cannot be cast to
org.drools.workflow.core.node.EventNode
at
org.drools.workflow.instance.node.EventNodeInstance.getEventNode(EventNodeInstance.java:62)
at
org.drools.workflow.instance.node.EventNodeInstance.signalEvent(EventNodeInstance.java:36)
at
org.drools.workflow.instance.node.CompositeNodeInstance.signalEvent(CompositeNodeInstance.java:231)
at
org.drools.workflow.instance.impl.WorkflowProcessInstanceImpl.signalEvent(WorkflowProcessInstanceImpl.java:357)
at de.bdr.prototype.ProcessTest.main(ProcessTest.java:36)
Many thanks for any help!
