<div class =“post-text”itemprop =“text”>
  
    可以将具有NodeRefs的一组字符串传递给以下WebScript，例如：
  
   <pre>
 <code>
 public class WorkflowAttachmentsManipulator extends DeclarativeWebScript {
 private static final String WORKFLOW_MODEL_URI = "...";
 private WorkflowService workflowService;

@Override
 protected Map<String, Object> executeImpl(WebScriptRequest req, Status status) {
 Map<String, Object> model = new HashMap<>();

String taskId = req.getParameter("taskId");
        String addedItems = req.getParameter("addedItems");

String oldValue = "";

WorkflowTask workflowTask = workflowService.getTaskById(taskId);
 Map<QName, Serializable> taskProperties = workflowTask.getProperties();

Iterator taskIterator = taskProperties.entrySet().iterator();
        while(taskIterator.hasNext()) {
            Map.Entry taskPair = (Map.Entry)taskIterator.next();
            Object key = taskPair.getKey();
            if(key != null && 
                key.toString().equalsIgnoreCase("{" + WORKFLOW_MODEL_URI + "}package")) {

if(taskPair.getValue() != null) {
                    oldValue = taskPair.getValue().toString();
                    if(!oldValue.equals("[]")) {
                        oldValue = oldValue.replaceAll("[\\[\\]]", "");
                        addedItems = "[" + oldValue + "," + addedItems + "]";
                    } else {

if(addedItems.indexOf(",") > 0) {
                            addedItems = "[" + addedItems + "]";    
                        }
                    }
                }

taskProperties.replace(
                    QName.createQName(WORKFLOW_MODEL_URI, "package"), 
                    oldValue, 
                    addedItems);

workflowService.updateTask(workflowTask.getId(), 
                    taskProperties, null, null);

break;
            }
        }
        ...
    }

public WorkflowService getWorkflowService() {
        return workflowService;
    }

public void setWorkflowService(WorkflowService workflowService) {
        this.workflowService = workflowService;
    }
}

    此代码会覆盖特定任务的附件。
  
  
    其他文件需要与文档管理过程中涉及的文件区分开来。例如，它可以完成如下：
  
   <pre>
 <code>
 /**
* Returns items that have been added to the current value
*
* @method getAddedItems
* @return {array}
*/
getAddedItems: function ObjectFinder_getAddedItems() {
 var addedItems = [],
 currentItems = Alfresco.util.arrayToObject(this.options.currentValue.split(","));

var attachments = [];

for (var item in this.selectedItems) {
        if (this.selectedItems.hasOwnProperty(item)) {          
            if (!(item in currentItems)) {
                // modified for differentiation
                if (this.options.displayMode == "items") {
                    attachments.push(item);
                } else {
                    addedItems.push(item);                     
                }
            }
        }
    }

...

// call to the WebScript with attachments

// modified for merge
    return addedItems.concat(attachments);
},

</code>
 </pre>
  
    为了在过程变量中保存重写的附件，有必要定义该过滤器的监听器
     <code>
 complete
 </code>
     事件。
  
  
    此外，通过使用此技术，可以通过链从一个任务到另一个任务（通过更改）“传递”文件：
  
  
    听众
     <code>
 complete
 </code>
     事件：
  
   <pre>
 <code>
 public class TaskCompleteListener implements TaskListener {
 @Override
 public void notify(DelegateTask delegateTask) {
 DelegateExecution execution = delegateTask.getExecution(); 
 execution.setVariable("mswf_package", delegateTask.getVariable("mswf_package"));
 }
}

</code>
 </pre>
  
    听众
     <code>
 create
 </code>
     事件：
  
   <pre>
 <code>
 public class TaskCreateListener implements TaskListener {
 @Override
 public void notify(DelegateTask delegateTask) { 
 DelegateExecution execution = delegateTask.getExecution();
 delegateTask.setVariable("mswf_package", execution.getVariable("mswf_package"));
 }
}

</code>
 </pre>
  
    这解决了我的问题。
