For some reason, everytime I edit the iview id, the delta link in the page will be broken.
After I changed the iview id, the iview id that I added as delta link in portal page remain same, and seems like become a separate copy , rather than the original delta link.
This frustracted me as I have to remove the old iview , and add the new edited iview into the page again.
Why is this happen? (I am very sure I didn't accidentally add the iview as copy, instead of delta link)
By the way, I am in NW04s SP9.
Thanks for help.
