As Hilmar said, should be something in the SQL of the view - depending on how you defined that field. Just make sure it's something that has a fixed length, and yields the same length when you USE ... NODATA.

Though, if its width may be changing, you should be getting error 1496 (or something like that) - view definition has changed.

My trick to catch such things was to open the view with NoData, List Structure. Then open it with data, list structure again, and compare. If everything's the same, you should be fine. If not - blame the fields which have different structure.
