LiveCycle ES: duplicate user queues appearing in Workspace ES

Issue

Users have duplicate queues in Workspace in Adobe LiveCycle ES 8.2.1. The first queue is the user’s personal queue (in blue below), and the second seems to be a shared queue (in red below).

 

Reason

Duplicate queues can appear if you had a custom application in LiveCycle 7 that created more than one queue per user. By default, LiveCycle doesn’t create more than one queue per user. LiveCycle clients, like Workspace (LC ES) and FormManager (LC 7) do not support multiple queues for the same user. The workflow engine in the background does support multiple queues per person, but this functionality is rarely used.

When there are multiple queues for a user, each queue has a row with a unique ID in TB_QUEUE. The ID in the default_queue_id column is the ID of the queue that workspace always uses for that user.

Solution

Remove the duplicate (shared) queue from the TB_QUEUE table. Before deleting the queue, run the following query to ensure that there are no assignments referencing the shared queue:

Select count(*) from tb_assignment where queue_id = xxx

Where xxx is the queue ID of the queue that is not the user’s default queue. That is, the queue ID not listed in the default_queue_id column.

LiveCycle ES: Workspace Group queue does not refresh automatically to show new tasks

Issue

If you are using group queues in Workspace ES you may notice that new tasks assigned to one of your group queues are not showing up automatically.  The user queues always refresh and show the new tasks automatically, but the group queues do not.

Solution

This issue has been fixed in ES 8.2.1.3 and later versions.  A patch is available to fix this issue in LiveCycle 8.2.1.2. Contact support if you require this patch, to ensure that it is compatible with your environment.

Additional information

If the patch does not fix the issue, check the server log for JGroups messages for more information about the possible root cause.

Also check the Global Workspace admin settings:

in LiveCycle Administration Console, click Services > LiveCycle Workspace ES > Global Administration. Under Export global settings, click Export.

Check the properties defined under server_remoteevents_JChannelConnectionProperties.  These are the connection properties for JGroups that are used to communicate between the server (on which a service event is processed by the RemoteEvent service) and all instances of Workspace ES.

If necessary, change the UDP values for the multicast IP address (mcast_addr), the multicast IP port (mcast_port), and the TTL for the multicast packets (ip_ttl). By default, the multicast IP address and port values are randomly generated and, generally, the values do not need to be changed. However, if your company has any network policies in regard to specific multicast ranges for multicast IP addresses, you sometimes need to change these values.

Note: The TTL must be greater than the number of network switches between the servers in the cluster.  However, if the value is set too high, it can cause multicast packets to travel into subnets, where they are discarded.

Do not change the remaining properties.

LiveCycle ES: Queues in the Workspace To Do view are not sorted

Issue

If you are using the To Do view in Workspace ES, you may notice that the queue list is not sorted. The queues appear in the list in the order in which tasks arrive, which can be confusing and difficult to find when you are a member of many groups and shared queues.

Solution

This issue is fixed in LiveCycle ES2 (9.0.0.0), and later versions, where the queues are now sorted alphabetically, with the group queues appearing above the shared queues as follows:

Personal Queue 

Group QueueA

Group QueueB

Group QueueC

Group QueueD

…..

Shared QueueA

Shared QueueB

…..

This arrangement is the most logical behavior, since the group queues are more commonly shared and usually occur more often for one user. They also tend to change (that is, receive tasks) more often than shared queues.

Additional information

There is a patch available for LiveCycle ES 8.2.1.2, so contact Enterprise Support if you require this patch.
