Hi, 
i tried to get the node Instance Id's using this method :


public Long getNodeInstanceId() {
                    if(getRfpi()!=null)
                    if(getRfpi().getNodeInstances().iterator().hasNext())
                              nodeInstanceId =  getRfpi().getNodeInstances().iterator().next().getNodeId(); 
                    return nodeInstanceId;

          }

WHERE getRfpi()  is defined by : 


public static RuleFlowProcessInstance getRfpi() {
                    if(processInstance!=null)                     
                              rfpi =(RuleFlowProcessInstance)processInstance; 
                    return rfpi;
          }

this worked fine BUT when i tried to get the node name by almost the same way :

public static String getNodename() {
                    if(getRfpi()!=null)
                              if(getRfpi().getNodeInstances().iterator().hasNext())
                              nodename= getRfpi().getNodeInstances().iterator().next().getNodeName(); 
                    return nodename;
          }


i got a NullPointerException pointing to this method..

Any Help please ?
