Hi,

I need to recuperate a document from one process and show this document in other form of other process.

I have two process:

This is the first process with the document. It call to 'activiti call'.

The second process need to recuperate the document and show it in the form:

With Java i can recuperate the document object but i can't put it in the second process:

@Autowired
    FormService formService;        
@Autowired
RelatedContentService relatedContentService;

@Override
    public void execute(DelegateExecution execution) throws Exception {
        System.out.println("*******************  RetieveAttachment  *******************" );
        
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        TaskService taskService = processEngine.getTaskService();        
        
         List<RelatedContent> contentList = relatedContentService.getFieldContentForProcessInstance(execution.getVariable("varGlo_idProceso").toString(), "form_scfhq_marcos_ini_englishframeworkversion", 1, 0).getContent();

//Show results

 if (contentList != null) {

               for (RelatedContent relCon : contentList) {
                   System.out.println("Content file: " + relCon.getName() + ", created: " + relCon.getCreated());
                   ContentObject co = relatedContentService.getContentStorage().getContentObject(relCon.getContentStoreId());
               }
        }
        
    }

Can anyone help me?

regards,
David

I implemented something in that direction for a customer of mine this year. This was required for passing a document from one process into another (child). For that I developed an execution listener in the child process that would use the process instance ID (and other parameters) provided by the parent process via variable mapping, look up the related contents and re-create them for itself.

The RelatedContentService and RelatedContentStreamProvider is all you should need for this. You look up the document via the related content service (like you already do), obtain its stream from the stream provider, and can then create a new related content again via the related content service. Once stored in as a related content for another process you can then show it in a form of that process with the typical attachment form field.
