This is an error I encountered recently specifically when you run into the error pointing to the "process for Initializing form", and for the life of mean I couldn't figure why it all of a sudden came up as the error did not a appear on other similar pages with similar logic. It turns out when I went to “DELETE” a record from a FORM, it needed to process the delete via a “Processing” process but also a BRANCH to go to another page after all was said and done.
IF it did not have this branch it would revert back to the same page that I did the delete and try to re-query the record I just deleted hence the “NO DATA FOUND” error!
Lesson learned.
