[sysumjc]

Hi, i'm use activiti 5.16.1, i don't use the activiti-explorer . and i define  two process. in first process  i start the second process:campaign-autodelete and pass the variable ${endTime}. when the endTime arrive , it will execute the servicetask, that is  the "com.xiaomi.appstore.campaign.ActivitiCampaignProxy$AutoDeleteCampaign".


campaign-autodelete.bpmn20.xml:
<blockcode>
……
  <process id="campaign-autodelete" name="campaign-autodelete" isExecutable="true">
    <startEvent id="startevent1" name="Start"></startEvent>
    <endEvent id="endevent1" name="End"></endEvent>
    <intermediateCatchEvent id="timerintermediatecatchevent1" name="TimerCatchEvent">
      <timerEventDefinition>
        <timeDate>${endTime}</timeDate>
      </timerEventDefinition>
    </intermediateCatchEvent>
    <serviceTask id="servicetask1" name="autodelete" activiti:class="com.xiaomi.appstore.campaign.ActivitiCampaignProxy$AutoDeleteCampaign"></serviceTask>
    <sequenceFlow id="flow1" sourceRef="startevent1" targetRef="timerintermediatecatchevent1"></sequenceFlow>
    <sequenceFlow id="flow2" sourceRef="timerintermediatecatchevent1" targetRef="servicetask1"></sequenceFlow>
    <sequenceFlow id="flow3" sourceRef="servicetask1" targetRef="endevent1"></sequenceFlow>
  </process>
……
</blockcode>

But it throws exception. I spend two days try to solve it but nothing. Please help me ,thank you very much!!

Hi,


Caused by: java.lang.InstantiationException: com.xiaomi.appstore.campaign.ActivitiCampaignProxy$AutoDeleteCampaign

Did you find out why it is not possible to instantiate AutoDeleteCampaign? (e.g. do not use inner class (or make inner class static)).

Regards
Martin
