Cannot find activity in ProcessDefinition

kikyou1986 — Tue, 31 Mar 2015 03:07:55 GMT

Hi,I want to find a certain activity in a ProcessDefinitionImpl object using method #findActivity(activityId), but it returns null every time. Below is the process picture. It is a simple Manager approval process. the applicant fills the application form first, then the manager approves it or reject

Try using the method on the repositoryService.getBpmnModel() to get the BpmnModel, which you can then use to get information about your activity

Hi jbarrez, how can I get the ActivityImpl ojbect with certain activityId from the BpmnModel object?

ok. I solved this by getting ProcessDefinitionImpl object with the following code:
<java>
ProcessDefinitionImpl pd = (ProcessDefinitionImpl) ((RepositoryServiceImpl) repositoryService)
    .getDeployedProcessDefinition(processDefinitionId);
</java>
This ProcessDefinitionImpl object will have all activity infomation in it.

I reckon that with the former approach, it is designed to have no activity infomation in it. The former approach I was using is:
<java>
ProcessDefinitionImpl pd = (ProcessDefinitionImpl) repositoryService
   .createProcessDefinitionQuery()
   .processDefinitionId(processDefinitionId).singleResult();
</java>

Correct. RepositoryService.getProcessDefinition() would do the same, and does not need the cast.
