System

If I call the methods that add files, comments, variables, etc to a WFworkflow or WFtask, do I have to call Refresh to ensure that that data is returned if I subsequently call GetFiles, GetVariables, etc. or is that taken care of for me? It wouldn't need to re-retrieve the XML, just have those methods update the in-memory XML. Seems like it should at least be an option to the add methods (-refresh => 1 or something), but I don't see it in the code or docs.
