heh, I smiled when I saw what you did with the if-then-else to handle the first item in the list. I had exactly the same challenge in my Global Announcement tracking demo. I solved it in a similar (but not identical) way:
- Read By: Text column containing a comma separated list of User ID’s (my “items” list)
- tp-first-user: Template containing the current User ID
- tp-subsequent-users: Template containing the current contents of Read By, plus a comma, plus the current User ID
- ite-new-read-by: if-then-else to determine which template column to use. If Read By is empty, use the first one. Else use the second one.
One thing I hadn’t figured out was a good way to remove items (users) from the list, so was particularly interested in what you did there. Very clever and will definitely be making use of that. Thanks!
