We have a use case where we will need to set the event dates of a record folder using a Workflow SDK Script activity.  We have are at a stage where we have the required dates and event IDs stored in a C# Dictionary entry, but are having trouble setting and saving the event dates.  This is the code section that we are currently working with:

foreach (KeyValuePair<int, DateTime> eventDate in AssignedEvents) {
        ei.GetParentFolder().GetRFProperties().SetEventDate(eventDate.Key, eventDate.Value);
}
ei.GetParentFolder().GetRFProperties().Save()

where:

EntryInfo ei = this.BoundEntryInfo;

and:

Dictionary<int, DateTime> AssignedEvents = new Dictionary<int, DateTime>();

Are we missing any required lock/unlock statements, or possibly misusing the SetEventDate() method?  Any help is appreciated.
