Hi!
The HtmlFileUploadRenderer seems to have some problems with empty Strings as
value of the value attribute of the inputFileUpload tag. When I set this
value to null, it works fine, but when I use an empty String, I get the
following runtime error (MyFaces Nightly 20051130):
java.lang.ClassCastException
