dmcheng Errors when inserting TaskRelation records
I have a client who wants the ability to clone a task that has multiple contacts. They would make slight changes to the cloned task (Assigned To, etc) but the multiple contacts would remain the same.
I'm getting a DUPLICATE_VALUE error when I tried to insert the cloned TaskRelation records and I can't figure out why. Do I need to create the task relation records in a different way?
Here's what I'm doing:
I retrieve the TaskRelation records for the original task, use the clone() list method, then insert the cloned Task, then replace the TaskId with the cloned task Id, and attempt to insert the cloned taskRelation records.
The error detail is:
System.DmlException: Insert failed. First exception on row 0; first error: DUPLICATE_VALUE, duplicate value found: duplicates value on record with id: : []
Here are the code snippets:

Here are the code snippets:
originalRelations = [SELECT RelationId, TaskId, IsWhat FROM TaskRelation
WHERE TaskId = :originalTask.Id AND IsWhat = false];
// Don't preserve Id, deep clone.
cloneTask = originalTask.clone(false, true);
cloneRelations = originalRelations.deepClone(false);
...
...
insert cloneTask;
for (TaskRelation relation : cloneRelations) {
relation.TaskId = cloneTask.Id;
}
insert cloneRelations;
When I construct the clone TaskRelation list in a loop and skip the existing Task.WhoId, then it works.
