Cannot fetch 'My Tasks' when the user is in pooled task

[amitev]

Hi all! I have the following case:
A task where users are added to a pool review task. When the adding task is done, tasks are assigned to the selected users. When one of these users opens Alfresco Share an error message "Error loading items" in "My Tasks" dashlet.

The following exception is printed in the console:

I debugged the code and in WorkflowServiceImpl.isUserInPooledActors() there are the following lines:

final Collection<?> actors = (Collection<?>)task.getProperties().get(WorkflowModel.ASSOC_POOLED_ACTORS);        if (actors != null && !actors.isEmpty())        {            for (Object actor : actors)            {                // retrieve the name of the group                Map<QName, Serializable> props = nodeService.getProperties((NodeRef)actor);                String name = (String)props.get(ContentModel.PROP_AUTHORITY_NAME);                …..‍‍‍‍‍‍‍‍‍‍‍

In my case the cm:authorityName (ContentModel.PROP_AUTHORITY_NAME) attribute is null and this causes the exception. What is wrong with this and how to fix it?

Looks like the pooledreview is not meant to work with list of assignees instead of list of group assignees. Is that true and could that be changed?

[amitev]

I implemented my own version of WorkflowServiceImpl where I allow adding users as actors to a pooled review. If someone needs the code I can provide it.

I have the same problem. Could you put here your code?

Thanks!!
