Simone Gianni resolved LABS-194.
--------------------------------
Resolution: Fixed
First step implemented, if a setParam...(FileItem item) is found on a web
handler, the corresponding uploaded file is passed.
This makes handling of uploaded files possible from a web handler.
Now, we need automatic handling of it when the files maps directly to a bean
property, both in input and output. Anyway, this is a very hard topic :
- How to render a file? With a link to download it? Being ShowBean a producer
and not a handler, where should this download link point to? This could be
easily solved if unification of producers and handlers were in place (see
LABS-192).
- How to handle a file upload in a stateless environment? While string values
are "stored" on the client and passed each time the form is submitted, we don't
want (and cannot have) this happening for files, so they must be stored
somewhere on the server in a stateful manner, which then involves cleaning it
up.
- In both cases, in a bean, we will want to store the raw data (as an input
stream probably), but filename and mime-type are useful informations we want to
store somehow, and reuse for output.
I'm going to defer automagic handling of files since currently not enough use
cases have emerged to understand properly where the "pareto line" lays.

>
> Using commons-fileupload and permitting a setParam with a java.io.File
> argument could be a starting point.
> Then, also provide infrastructure in foundation beans to denote a bean field
> taking a file (or a stream + metadata), in foundation validation for
> validating it (maximum size, accepted mime types etc..), and in forms and
> showbean to properly display and handle it.
> Also, it should be able to use a file as an image, displaying it during the
> showbean.
