Ok, I finally figured this out. I had to edit the UUI file using notepad++. If you search for TSuperTrendMgr, you will see a SOH character followed by 11 characters…most of which are NUL. One of them is not. I changed that to a NUL character as well…and bam. The next time I opened my project and added a new Supertrend, it was given a 0 id. Now I just have to recreate all 40+ of my supertrends…but at least I found a solution!
