this is listener
public class SignUsersListener implements ExecutionListener {
@Override
public void notify(DelegateExecution execution) throws Exception {
// String variableKey = currentActivityId+"assigneeList";
List<String> list = new ArrayList<>();
list.add("张三");
list.add("李四");
list.add("网民");
// repositoryService.get
execution.setVariableLocal("collection",list);
}
}
I want to set the ‘collection’ variable in the ‘SignUsersListener’,But when I complete the previous task, ‘SignUsersListener’ is not executing,the program will throw an exception：
org.camunda.bpm.engine.ProcessEngineException: ENGINE-02025 Variable 'collection' is not of the expected type 'Collection'.
