[Haskell-cafe] Question Formlets, file upload

Dear all, I am using the library Text.XHtml.Strict.Formlets to build a validating form. I use the function "file" to get a file upload widget. The encoding is set to multipart. I want to check, if the user entered something or left the widget empty. However, when entering nothing, instead of an empty string, I always get a string like "/tmp/12101" which corresponds to an empty file. It would be nice, if I could check for the empty string to see, weather the user entered something or not into the upload widget. I appreciate any hints to achive this and wish you a good day, Heinrich -- -- hoerdegen@funktional.info www.funktional.info --
