Thanks for the workaround, Jason. However, I encountered another problem as noted below:
To test out your recommendation, I created just a simple form using FB where I had just a few form elements including one file form element. As expected, FB was forcing validation on the file form element. I was not requiring validation on any of the other elements.
I then went into the server behavior panel per your instructions and deleted the validation rule associated with the file form element (using the minus sign). I then clicked the Ok button to close the dialog window but I immediately got the following error message: "You must specify at least one Server Variable to validate". My only other option, from what I could tell, was for me to click Cancel and I am therefore unable to delete the validation rule on the file form element.
However, if I do make at least one of the other form elements requiring validation, I then have two validations rules and I can delete the one associated with the file form element. But then again, I now have required validation on a different form element where I don't want it either.
Not sure this is another bug or not, but thought I would pass this information on to you.
In any case, you can mark my original issue as RESOLVED BY WORKAROUND, sort of. Thanks.
