Seam 2.2.0.GA: Bijection and BusinessProcess Interceptors

[rissp]

Hello!
i have some problem with jbmp process in seam.
Main process definition:

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

<process-definition xmlns="urn:jbpm.org:jpdl-3.2"
     name="simple">
     
     <start-state name="start">
          <transition name="to task" to="some task" />
     </start-state>
     
     <task-node name="some task">
          <task name="HumanTask">
               <assignment actor-id="#{creator}"></assignment>
          </task>
          <transition to="Some subprocess"></transition>
     </task-node>

     <process-state name="Some subprocess">
          <sub-process name="subprocess" binding="late"/>
          <variable access="read,write" name="neededVariable"
               mapped-name="variable"></variable>
          <transition to="end" name="to_end">
               <action></action>
          </transition>
     </process-state>
     <end-state name="end"></end-state>
</process-definition>

Sub process definition:

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

<process-definition  xmlns="urn:jbpm.org:jpdl-3.2"  name="subprocess">


     <start-state name="start">
          <transition to="Human task"></transition>
          <event type="node-leave">
               <script>System.out.println(executionContext.getVariable("variable"));</script>
          </event>
     </start-state>

     <task-node name="Human task">
          <task name="subHumanTask"></task>
          <transition to="end"></transition>
     </task-node>

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

In task-node 'some task' we need to create and set into process a variable, which is needed for subprocess.

In java code it looks like this:

@Out(required = false, scope = ScopeType.BUSINESS_PROCESS, value = "neededVariable")
private String someString;

@EndTask
public void endHumanTask(){
  someString = "some value for SubProcess";
}

There is a problem.

• 1. BijectionIntercepter fills up BisinessProcessContext

• 2. BusinessProcess executes endTask, and process goes to executions (neededVariable doesn't exists in jBpm process, only in BisinessProcessContext)

• 3. After that interceptor flushes a variable from BisinessProcessContext to jBpm ContextInstance of current process

Is it common seam behaviour when seam works with subProcess/nonhuman task?
