Strange backingMapListener / processor behaviour

Question

Hi,
I have cache X and backingMap listener on that cache.
On insert of entity with key Z the listner invokes (asynchronously) an invocable via the invocation service.
Inside the invocable I run an EntryProcessor against the same cache X and key Z - in some situations (like repartition) the processor does not see the value.
Could it be that my invocable is started before the cache.add() operation is yet completed?
BR,
Georgi

Hi,
Once again (just to be sure) - the listener is a BackingMap listener. It is registered with the wflCache.
The effect is observed when adding new node to the cluster (wflCache is partitioned) and the problem manifests itself only on the new node!
I have some suspicion that I am getting mismatch in the key hash code when the entry is transferred.
Code below.

     protected void onMapEvent(MapEvent evt) {
          if (evt.getId() == MapEvent.ENTRY_INSERTED){
final WorkflowEntry wfe = (WorkflowEntry) ctx.getValueFromInternalConverter().convert(evt.getNewValue());
               final WorkflowKey wflKey = (WorkflowKey) ctx.getKeyFromInternalConverter().convert(evt.getKey());
               invocationService().execute(
                         new WFLDriver(wflKey, wfe, wflCache, masterCache, detailCache),
                         AssetsBean.getInstance().getLocalMemberSet(),
                         null);
public class WFLDriver extends AbstractInvocable implements ExternalizableLite{
     public void run() {
          wflCache.invoke(wflKey, new AdvanceProcessor(WorkflowStates.ChildUpdateDone));
public class AdvanceProcessor implements EntryProcessor, ExternalizableLite {
     protected transient Logger log = Logger.getLogger(this.getClass());
     private WorkflowStates targetState;
     public AdvanceProcessor() {
     public AdvanceProcessor(WorkflowStates newState) {
          this.targetState = newState;
     public Object process(Entry arg0) {
          if (!arg0.isPresent()) {
               log.error("non-eixstent value for wfl item " + arg0.getKey() + " while advancing to " + targetState);
          } else {
               WorkflowEntry ee = ((WorkflowEntry) arg0.getValue());
               if (ee == null)
                    log.error("null value for wfl item " + arg0.getKey() + " while advancing to " + targetState);
               else {
                    ee.advanceTo(targetState);
                    arg0.setValue(ee);
          return null;
}
