<div class="jive-rendered-content"><p>Hi All,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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 "<strong>printHelloWorld</strong>" the execution will wait in that. And meanwhile as the other transition node in the fork is a state node (<strong>Being1</strong>) it also wait in that node.</p><p><span style="text-decoration: underline;"><strong>snippet of Main process(helloworld.jpdl.xml)</strong></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><fork g="101,278,80,40" name="printHelloWorld"><br/>  <transition g="56,193:-39,-18" name="Being1" to="Being1"/><br/>  <transition g="137,177:24,8" name="review" to="review"/><br/>  <br/> </fork><br/> <join g="855,204,80,40" name="join1"><br/>  <transition to="printHelloWorld2"/><br/> </join><br/>     <state name="Being1" g="0,0,80,40"><br/>  <transition to="join1" g="877,666:"/>-<strong>-------Other execution is active at this node.
