Vpl,
I want to second what Mark is asking. I suspect you are a long way down a
solution path, yet the problem is most likely a conceptual one at a higher
level.
Personally I no longer set status flags/tags or fields because when they
change you have to remove previous values. Instead I prefer to determine
the status at any point in time using other information on a tiddler.
For example I have item-started item-completed and item-cancelled on each
task tiddler. Each of these fields can be date/time stamped when started
completed or cancelled
- It is new if item-started exists without a value (and not
completed/cancelled)
- It is work in progress if it item-started is date stamped (and not
completed/cancelled)
[all[current]has[item-started]!has[item-completed]!has[item-cancelled]]
- It is inactive it date stamped completed/cancelled
I have now taken this much further such as allowing item-started at a
future date to schedule its start later and a lot more.
PS The "has[fieldname]" operator asks if a field is present and has a
value, and the "has:field[fieldname]" asks if a field is present (can be
empty)
Regards
Tony
