ForEachForkActionHandler implements pattern 14, Multiple Instances with Run Time Knowledge.  This is a Jbpm 3.0 port of the Jbpm 2.0 JbpmCustomForkhandler.

Example Usage: The calling code would set variable assets with a java.lang.List.

<process-definition name="foreachfork-example">
    <start-state name="start">
        <transition to="foreachfork" ></transition>
    </start-state>
    <node name="foreachfork">
        <action class="com.xxx.workflow.ForEachForkActionHandler" config-type="bean">
            <listVariable>assets</listVariable>
            <as>asset</as>
        </action>
        <transition name="one" to="one"></transition>
        <transition name="two" to="two"></transition>
    </node>
    <node name="one">
        <script>
                System.out.println("one: " + asset);
        </script>
        <transition to="joinforeach"></transition>
    </node>
    <node name="two">
        <script>
                System.out.println("two: " + asset);
        </script>
        <transition to="joinforeach"></transition>
    </node>
    <join name="joinforeach">
        <transition to="end"></transition>
    </join>
    <end-state name="end"></end-state>
</process-definition>

executionContext.getProcessInstance().getJbpmSession().getSession().save(newToken);

use

executionContext.getJbpmContext().getSession().save(newToken);
