I’m trying to get all historic task instances filtered by candidate group but i cannot get any result.  
The same request for runtime task instance is working.  
After digging in database, i can see that ACT\_HI\_IDENTITYLINK is never populated while ACT\_RU\_IDENTITYLINK is.  
Do you know when historic identity link is supposed to be populated ?

I used this method for getting historic task instances (no result) :

```
List<HistoricTaskInstance> hrTasks = cmmnHistoryService.createHistoricTaskInstanceQuery()
            .taskCandidateGroupIn(Arrays.asList("group1","group2"))
            .caseInstanceId(caseInstanceId)
            .list();

```

And this one for getting task instances (one result) :

```
    List<Task> tasks = cmmnTaskService.createTaskQuery()
            .taskCandidateGroupIn(Arrays.asList("group1","group2"))
            .caseInstanceId(caseInstanceId)
            .list();

```

Thank you
