NSOutlineView setAutosaveExpandedItems

Im trying to get my outline view to work with 
setAutosaveExpandedItems, using the code listed below

[item timeStamp] returns a unique NSString (used extensively 
throughout my app)

both datasource methods are called and I have verified that the 
timestamps are properly archived and unarchived.... however the 
outlineviews expanded state is not restored.

incidentally if i archive and unarchive the actual items, rather than 
the items timestamps i get the same issue, I would not want to do 
that as the items are complex and my would be inefficient, however I 
am led to believe by the docs that it should work.

Any ideas? I can find no sample code with this working.

Thanks in advance

Nick
