Receive Event From Invoked Session and Extract Event Data

The invoking session can extract data from the event sent by the invoked session using the <finalize> clause, as shown in the following sample.

<scxml version="1.0" xmlns="http://www.w3.org/2005/07/scxml" 
        xmlns:queue="www.genesyslab.com/modules/queue" 
        xmlns:dialog="www.genesyslab.com/modules/dialog" 
        initial="initial">
  <datamodel>
    <data id="DN"/>
  </datamodel>
  <state id="initial">
    <transition event="interaction.added" target="invocation"/>
  </state>
  <state id="invocation">
    <invoke 
    src="'http://localhost:9090/strategies/01_BASIC/_aux/ReturnDN.xml'" type="scxml">
      <finalize>
        <script>if ( _event.name == 'DN' ) _data.DN=_event.data.DN; </script>
      </finalize>
    </invoke>
    <transition event="done.invoke.invocation.*" target="routing"/>
    <transition event="error.invoke.invocation.*" target="error"/>
  </state>
  <state id="routing">
    <onentry>
      <queue:submit priority="5" timeout="20">
        <queue:targets type="dn">
          <queue:target name="_data.DN"/> 
        </queue:targets>
      </queue:submit>
    </onentry>
    
    <transition event="queue.submit.done" target="exit">
      <log expr="'DONE'"/>
      <log expr="_genesys.ixn.interactions[0].voice.ani"/>
      <log expr="'DONE'"/>
      <log expr="_event.data.targetselected"/>
    </transition>
    <transition event="error.queue.submit" target="error"/>
  </state>
  
  <final id="exit"/>
  <final id="error"/>
</scxml>
