I created a Public Group and added Roles as members. When I am querying the GroupMembers of that Group, I am getting the Ids for the Groups with Type Role. But when I am trying to query the Users/GroupMembers from the returned Group of type Role, no records are being returned.Here I have shared the class used to query members of a group and the result when we are passing a set of Ids of Groups with Type Role.

      Public class PublicGroupUtil{
      public static Set<Id> findUsersFromGroup(Set<Id> PublicGroupSet) {
         set<Id> userSet = new set<Id>();
         Set<Id> groupIdSet = new Set<Id>();
         String userType = Schema.sObjectType.User.getKeyPrefix();
         Map<Id,Group> groupMap = new Map<Id,Group>([select Type from Group where id in:PublicGroupSet]);
         for(GroupMember member : [select UserOrGroupId from GroupMember where groupId =:PublicGroupSet]) {
            if(((String)member.UserOrGroupId).startsWith(userType)) {
         if((groupIdSet.size() > 0) && (Limits.getLimitQueries() > Limits.getQueries())) {
        return userSet;

I have then passed a set of Group Ids whose type is Role to the method:

Set<Id> lstOfGroupIds = new Set<Id> ();
for(Group g: [SELECT Id FROM Group WHERE Type = 'Role']){
System.debug('Role Type Groups size = '+lstOfGroupIds.size());
Set<Id> lstOfGroupMembers = new Set<Id> ();
lstOfGroupMembers = PublicGroupUtil.findUsersFromGroup(lstOfGroupMembers);
System.debug('GroupMembers size = '+lstOfGroupMembers.size());

The debug log gives the following result:

Execute Anonymous: Set<Id> lstOfGroupIds = new Set<Id> ();
Execute Anonymous: for(Group g: [SELECT Id FROM Group WHERE Type = 'Role']){
Execute Anonymous: lstOfGroupIds.add(g.Id);
Execute Anonymous: }
Execute Anonymous: System.debug('Role Type Groups size = '+lstOfGroupIds.size());
Execute Anonymous: Set<Id> lstOfGroupMembers = new Set<Id> ();
Execute Anonymous: lstOfGroupMembers = PublicGroupUtil.findUsersFromGroup(lstOfGroupMembers);
Execute Anonymous: System.debug('GroupMembers size = '+lstOfGroupMembers.size());

Why does the query not return any records?

  • I'm wondering if this is a recent change in behaviour within Salesforce. I'm discovering the same thing today, but various guidance out on the web indicates that this should work. Did you discover a workaround?
