Workflow and Exchange 2010 Tasks

Has anyone gotten Altiris to manage Exchange 2010 tasks? I am creating a project that allows departmental managment of teams and their tasks. I have gotten a lot done, but i am trying to allow individuals to delete their tasks from within the workflow project. When i execute the LogicBase.Components.MicrosoftExchange.Exchange2007.DeleteTaskComponent I get the error "AffectedTaskOccurrences attribute is required for Task items.". I understand that exchange needs the AffectedTaskOccurrences variable to determine if i want to delete all occurrences or just one instance, but i can't find where to set this in the component. Any help would be appreciated.
