[rules-users] Question regarding drools example

Hi, I'm new to drools and i'm trying to learn through the drools examples. Inside the file org.drools.examples.process.order.logging.drl I see this : workItem: WorkItemImpl( state == WorkItemImpl.PENDING ) from workItemNodeInstance.getWorkItem() The PENDING constant seems to be missing in the org.drools.process.instance.impl.WorkItemImpl class Am I missing something ? Thanks Yannick
