    rollbackTransaction issue

    Juan Sanmarco Newbie

      Hi all,
      I have the following process definition:

      <?xml version="1.0" encoding="UTF-8"?>
      
      <process-definition name="forkWait">
       <start-state name="start">
       <task>
       <controller>
       <variable name="color" />
       <variable name="size" />
       </controller>
       </task>
       <transition name="toT1" to="task1"></transition>
       </start-state>
       <end-state name="end"></end-state>
       <node name="task1">
       <action name="action1" class="com.lumina.jbpm.tasks.Task1"></action>
       <transition name="toFork1" to="fork1"></transition>
       </node>
       <node name="task2">
       <action name="action2" class="com.lumina.jbpm.tasks.Task2"></action>
       <transition name="toJoin1" to="join1"></transition>
       </node>
       <node name="task3">
       <action name="action3" class="com.lumina.jbpm.tasks.Task3"></action>
       <transition name="toJoin1" to="join1"></transition>
       </node>
       <node name="Task5">
       <!-- <transition name="toEnd" to="end"></transition> -->
       <action class="com.lumina.jbpm.tasks.Task5"></action>
       <transition name="toend" to="end"></transition>
       </node>
       <fork name="fork1">
       <transition name="toEsperar1" to="esperar1"></transition>
       <transition name="toEsperar2" to="esperar2"></transition>
       </fork>
       <state name="esperar1">
       <transition name="toTask2" to="task2"></transition>
       </state>
       <state name="esperar2">
       <transition name="toTask3" to="task3"></transition>
       </state>
       <join name="join1">
       <transition name="toTask5" to="Task5"></transition>
       </join>
      </process-definition>


      1) I start the processInstance which runs until states "esperar1" and "esperar2" are reached.
      2) Then I persist the processInstance and perform a jbpmSession.commitTransaction().
      3) I recover the processInstance from the DB and signal on "toEsperar1" ( processInstance.findToken("/toEsperar1").signal() ) which makes "task2" to be executed and reach "join1" join node.
      4) I persist the processInstance and perform a jbpmSession.commitTransaction().
      5) After a while, I recover the processInstance from the DB and signal on "toEsperar2" ( processInstance.findToken("/toEsperar2").signal() ) which makes "task3" to be executed, reaching "join1" join node (now both tokens arrived to the join) and "task5" being executed.
      6) Now I rollback the transaction by calling jbpmSession.rollbackTransaction().
      7) I recover the processInstance from the DB and signal again on "toEsperar2" ( processInstance.findToken("/toEsperar2").signal() )

      At this time, "task3" is NOT executed but "task5" executes normally.
      My question is why "task3" is NOT executed if in 6) I rolled back to a step before it is executed?
