copied code from a view, then recreated the view, then errors

wwii I think I just encountered this same thing today. It would appear that the field names are tied directly to the table and there is an underlying reference included. What I mean, is that just because the table name is the same, doesn't mean the fields in the visuals will automatically know you put a new replacement table.

As an example: You have a table 'Sales', but it most likely is 'Sales1' and when you delete the first table and re-create the view it is 'Sales2'... so all the fields in your visuals will break because you deleted the 'Sales1' table.

This is purely just observed behaviour when I replaced a table today, and some educated guessing as to why all the visuals fail to work.
