task.setAssignee() does not affect ACT_HI_ACTINST

Hi all,

it seems that when doing task.setAssignee(), the new assignee is only updated in ACT_RU_TASK and ACT_HI_TASKINST, but not in ACT_HI_ACTINST. This is an excerpt from

  public void setAssignee(String assignee) {
    if (assignee==null && this.assignee==null) {
    if (assignee!=null && assignee.equals(this.assignee)) {
    this.assignee = assignee;

    CommandContext commandContext = Context.getCommandContext();
    if (commandContext!=null) {
        .setTaskAssignee(id, assignee);
      // if there is no command context, then it means that the user is calling the
      // setAssignee outside a service method.  E.g. while creating a new task.
      if (commandContext!=null) {

It's obvious that the HistoricTaskInstance is updated, but why not also the HistoricActivityInstance? Am I doing something wrong? This is happening in a process where the first user task comes right after the process start and has only a candidate set, no assignee. So I claim it manually (via CDI BusinessProcess bean).

Why I need this: I would like to know who made updates to process variables, and since there's no link from ACT_HI_DETAIL to ACT_HI_TASKINST, I have to rely on the information from ACT_HI_ACTINST), see also this thread.

Thanks for your input :-)
