Hi Viv,

 

Please try below :-

 

 

List<GroupMember>gpm=[SELECT Id,UserOrGroupId,groupId FROM GroupMember where UserOrGroupId=<Some id>];

List<Id> UserIds = new List<Id>();

for(GroupMember fm : gpm){
UserIds.add(fm.UserOrGroupId);
}

delete gpm;

Group gp = new Group(Name='ABC',Type = 'Regular');
insert gp;

List<GroupMember> gpmnew = new List<GroupMember>();
for(integer i=0;i<UserIds.size();i++){
for(Id idd:UserIds){
GroupMember gm =  new GroupMember(GroupId=gp.id,UserOrGroupId=idd);
gpmnew.add(gm);
}
}

insert gpmnew;

Error: Invalid Data.
Review all error messages below to correct your data.
Apex trigger createUser caused an unexpected exception, contact your administrator: createUser: execution of AfterInsert caused by: System.DmlException: Insert failed.

Viv,

 

You can create a Handler class for the Trigger and there you can have two methods one future and other synchronous.Then,you won't hit this error as you will be updating in different context.
