sub-process definition is null

[scholtz.albert]

I have an old problem or so it seems. I have the following process definition:

<?xml version="1.0" encoding="UTF-8"?>

<process-definition  xmlns=""  name="KYHProcess">

     <start-state name="start-state1">
          <transition to="viewAccount" name="toViewAccount"></transition>
     </start-state>

     <state name="viewAccount">
          <transition to="end-state1" name="toEndState1"></transition>
          <transition to="updateThreshold" name="toUpdateThreshold"></transition>
          <transition to="addCompanionProducts" name="toAddCompanionProducts"></transition>
          <transition to="viewBill" name="toViewBill"></transition>
          <transition to="resendVPin" name="toResendVPin"></transition>
     </state>

     <process-state name="updateThreshold">
          <sub-process name="updateThreshold"></sub-process>
          <transition to="viewAccount"></transition>
     </process-state>

     <process-state name="addCompanionProducts">
          <sub-process name=""></sub-process>
          <transition to="viewAccount"></transition>
     </process-state>

     <process-state name="viewBill">
          <sub-process name=""></sub-process>
          <transition to="viewAccount"></transition>
     </process-state>

     <process-state name="resendVPin">
          <sub-process name=""></sub-process>
          <transition to="viewAccount"></transition>
     </process-state>

     <end-state name="end-state1"></end-state>
</process-definition>

I have the updateThreshold process specified as followed:

<?xml version="1.0" encoding="UTF-8"?>

<process-definition  xmlns=""  name="updateThreshold">


     <start-state name="start-state1">
          <transition to="updateThreshold"></transition>
     </start-state>

     <task-node name="updateThreshold">
          <transition to="updateSuccessful"></transition>
     </task-node>

     <decision name="updateSuccessful">
          <transition to="success"></transition>
          <transition to="failed" name="to failed"></transition>
     </decision>

     <end-state name="failed"></end-state>
     <end-state name="success"></end-state>
</process-definition>

As i signal to enter the updateThreshold process-state, i get the following exception: org.jbpm.JbpmException: can't create a process instance when processDefinition is null.

I deploy my processes using jbpm admin console, first updateThreshold and then KYHProcess. I also added 

<bean name="jbpm.sub.process.resolver" class="org.jbpm.graph.node.DbSubProcessResolver" />

to my jbpm.cfg.xml and still the same result. Using jBPM 3.2

Found myself on the same problem.
There's a useful talk about here

Try adding the binding="late" in the following way

     <process-state name="updateThreshold">
          <sub-process name="updateThreshold" binding="late"></sub-process>
          <transition to="viewAccount"></transition>
     </process-state>
