I'm trying to change an application that uses Visual Extend and SDT. I have no documentation on the framework, and have run into a problem after deleting a fields. I added a field to a table, put it on a form and was playing around and testing. The next day, I decided to remove the field from the form and delete it from the table. At this point the application halts when accessing the form, and complains about the missing field.

I'm guessing that at run time, it puts some information about that field possibly in one of the SDT tables, and is now confused.

IF I had the field back in the table, then it runs ok
