Hi All,

I am having a  main JBPM process(helloworld.jpdl.xml) and in that having a fork of that one transition to a sub process and the other to a state node. And these to should transition to a join join1 node.  When I started the process it sucessfully reaching the fork and both two transitions are reached. But As the subprocess contains a state node "*printHelloWorld*" the execution will wait in that. And meanwhile as the other transition node in the fork is a state node (*Being1*) it also wait in that node.
*snippet of Main process(helloworld.jpdl.xml)*

<fork g="101,278,80,40" name="printHelloWorld">
  <transition g="56,193:-39,-18" name="Being1" to="Being1"/>
  <transition g="137,177:24,8" name="review" to="review"/>
  
 </fork>
 <join g="855,204,80,40" name="join1">
  <transition to="printHelloWorld2"/>
 </join>
     <state name="Being1" g="0,0,80,40">
  <transition to="join1" g="877,666:"/>-*-------Other execution is active at this node. Waiting for an external signal*
 </state>
 <sub-process name="review" sub-process-key="SubProc" g="0,0,80,40">
  <transition to="join1" g="877,666:"/>
 </sub-process>

*subporcess (SubPoc.jpdl.xml)*

<process name="SubProc" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl">
 <start g="372,19,80,40">
  <transition to="printHelloWorld"/>
 </start>
    <state name="printHelloWorld" g="0,0,80,40">------*Subprocess execution is waiting in This node. Waiting for an external signal.*
  <transition name="printHelloWorld1" to="printHelloWorld1" g="877,666:"/>
 </state>
 <java g="539,206,138,40" method="printHelloWorld" name="printHelloWorld1">
  <transition g="606,516:-39,-18" name="theEnd" to="theEnd"/>
 </java>
 <end g="369,491,80,40" name="theEnd"/>
</process>

I have used *processInstance.getExecutions()* which gives the active executions and the result is:

*[execution[helloWorld.13.Being1], execution[helloWorld.13.review]]*

Then by using *openExecutio.getSubProcessInstance().getId();* I find out the subprocess instance id and is *[SubProc.21].*

Then I signaled the subprocess using *executionService.signalExecutionById(id,"printHelloWorld1");* And it sucessfully transitioned and it prints :
*<---------------->*
*   HELLO FELIX!*
*<---------------->*

So the subprocess sucessfully *completed*. But when I check activeactivity name in the subprcess it still shows *printHelloWorld state node (*by using *openExecutio.getSubProcessInstance().findActiveActivityNames()---o/p is --[printHelloWorld])*

And also when I checked active executions using *processInstance.getExecutions() it still gives:*

*[execution[helloWorld.13.Being1], execution[helloWorld.13.review]]* that means both two forked transitions are in *wait* state.

So my doubt is how can I transition the subprocess fron one state to another instead of using *executionService.signalExecutionById(id,"printHelloWorld1");?*
I have attached the sample application with this. Can you please give a solution as soon as possible?

*Thank You and Regards,*
*Felix K Jose*
