Would you try something for me?  Stick a routine in that class, call it
getCurrentSheets(), with exactly the same code as the _v_currentSheets
method, then call it from your code in place of iterating through
propertysheets?  I have a feeling it'll provide a clearer error message.
(That's the only problem with ComputedAttributes - errors that break them
manifest as AttributeErrors, hiding the true error.)  Thanks.
