I'm getting a 1320288991: File name is invalid exception - could be related...

Solution seems to be setting the type of the field to "file" - there is a problem in using FAL references. The precise problem appears to be resolving the name of a FAL file reference when resolving it from inside a flex form structure; resolving the actual filename works but for some reason it is not being used as label for the corresponding option.
