[jboss-dev-forums] [Design of PVM (Process Virtual Machine)] - Composite execution problem

[beeke]

hello,


  | public void testSequence(){
  |         ClientProcessDefinition processDefinition = ProcessDefinitionBuilder
  |         .startProcess("propagate")
  |             .startActivity("sequence", new Sequence())
  |                 .initial().needsPrevious().transition("end")
  |                 .startActivity("one", new WaitState())
  |                 .endActivity()
  |                 .startActivity("two", new WaitState())
  |                 .endActivity()
  |                 .startActivity("three", new WaitState())
  |                 .endActivity()
  |             .endActivity()
  |             .startActivity("end", new WaitState())
  |             .endActivity()
  |         .endProcess();
  | 
  |         ClientExecution execution = processDefinition.startProcessInstance();
  |         execution.signal();
  |         execution.signal();
  |         execution.signal();
  | }
  | 

Notice the line:.initial().needsPrevious().transition("end")
I want it execute like this:
(sequence(one -> two -> three)) -> end
In fact is sequence->end

I saw the source code, while activityImpl.createOutgoingTransition, the activity "end" is set to be a defaultTransition: defaultTransition = transition;

While executionImpl.proceed(), the "sequence" activity has defaultActivity, and will never executed as a block structed node.

How can PVM support block structed like this?
