We have a process that has a User Step where the initial user selection is assigned to a LC group. If that group contains more than 10 users, the workspace is not refreshing for any of the users after the first 10 when we invoke a process route. The task will disappear from workspace after the route has been invoked, but it will not reappear in the group queue. It works fine for the first 10 users in the group. The order of the users in the group seems to be determined by the user name.
Sounds like a bug. The default behaviour when querying for a list of users (in a group or otherwise) is to limit the response to 10 items.
What version are you running?
I am using Version 8.2.
Is there any way we can change the size of the query result?
No, it is baked into the service code we use to generated server side pushing of new tasks to Workspace users. You will need to report the issue to support to get a fix.
