Currently if I have a workflow task and I create a field in the dialog that is set to user of a group and multi-select and I have specified a group for the task assignment to display a list of users. I have found that if the group contains a role that the members of the role do not display in the list of user for the workflow field defined as user of a group. Only the individual users assigned to the group NOT the users assigned to the Role that is listed as a member of the group are displayed. All users including those users that are part of the group via being in the Role that is assigned to the group should be displayed.
