Igor, It has come up a couple of times on the user list, but in 1.4rc1 there was a change to FileUploadField to make it always use a model. Now, the new FileUploadField("id") constructor is practically useless, and I would venture to say that tons of apps out there (like mine do in numerous places), have always just used the ID constructor since nothing else was needed.
Why the change? At the very least, could we make the ID-only constructor call super(id, new Model<FileUpload>()) ?? Thanks! -- Jeremy Thomerson http://www.wickettraining.com
