jbpm - How to relate the <decision> and <state> in JPDL in JBPM4 to BPMN2.0 in JBPM7? -


i have simple 3 steps process definition have defined in jpdl jbpm4.3, , remodel using bpmn2 in jbpm7 have problem trying so. example, have jpdl looks (i simplified actual 1 quite complex):

<?xml version="1.0" encoding="utf-8"?> <process key="process_external_response" name="process_external_response" xmlns="http://jbpm.org/4.2/jpdl">     <start g="66,20,48,48">         <transition to="send_and_wait"/>     </start>     <state g="662,145,80,40" name="send_and_wait" continue="async" class="com.examples.sendandwaitstatehandler">         <transition g="-79,-18" name="completed" to="process_response"/>         <transition g="-85,-25" name="error" to="error_and_abort" />     </state>     <decision g="673,346,80,40" name="process_response" continue="async">         <handler class="com.examples.processresponsestatehandler">         </handler>         <transition g="-79,-18" name="completed" to="end"/>         <transition g="-79,-18" name="error" to="error_and_abort"/>     </decision>     <state g="501,345,92,52" name="error_and_abort" class="com.examples.abortstatehandler" continue="async">         <transition g="-45,-18" name="retry" to="send_and_wait"/>         <transition g="-45,-18" name="abort" to="end"/>     </state>     <end g="391,494,48,48" name="end"/>  </process>

basically, when process starts, creates request , send external system. then, goes wait state wait response. once got response, processes response , make decision if should proceed or error out. in event of error, process transition "error , abort" wait state user or timer can send signal "retry" application transition "send_and_wait" state again.how model using bpmn2.0 in jbpm7?
