Hey guys,

I tried to adapt this example webexample  http://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-example http://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-example to my use case where I execute the follwoing lines:

org.jbpm.workflow.instance.node.WorkItemNodeInstance currentNode = NodeFinder.findNodeInstance(MeyleTaskHandlerJPA.workItemdID, process);

org.drools.definition.process.Node nextNode = currentNode.getNode().getOutgoingConnections().values().iterator().next().iterator().next().getTo();

With help of the debugger I found out, that I get a NullPointer Exception when i call currentNode.getNode().

getNode() from class NodeInstanceImpl returns:

return ((org.jbpm.workflow.core.NodeContainer)
            this.nodeInstanceContainer.getNodeContainer()).internalGetNode( this.nodeId );

and here getNodeconteiner() from class WorkflowProcessInstanceImpl returns the return value of getWorkflowProcess() from same class which calls getProcess() from class ProcessInstanceImpl where the kruntime is null.

if (this.process == null) {
            this.process = kruntime.getKnowledgeBase().getProcess(processId);
        }

My question is: why is the kruntime null?
